#BreakingNews! 🚨 #LandBack in #Maine!

Land returned to #MikmaqNation will double tribe’s territory

Nearly 3,400 acres have been returned to the Aroostook County-based tribe.

by Reuben M. Schafir, June 22, 2026

"The #Mikmaq Nation is expanding. The tribe on Friday obtained title to #MesgilgMaqamigew, a nearly 3,400-acre parcel near #BridgewaterME. The land return is so large it will more than double the tribe’s holdings.

" 'For decades the Mi’kmaq citizens have seen their traditional hunting and gathering grounds disappear to development or private ownership not allowing access,' Chief #SheilaMcCormack said in a news release. 'This property will give our people a place for outdoor recreation, a place to teach our children how to hunt and fish, and a place we can pass down the traditions of our ancestors before they are forgotten.'

"Of the four #Wabanaki tribes, the Mi’kmaq Nation received federal recognition last, in 1991. It and the #HoultonBand of #Maliseet Indians hold far less land in Maine than the #PassamaquoddyTribe and #PenobscotNation, which each have more than 150,000 acres.

"#TheConservationFund negotiated a below-market value sale and purchased the parcel last year from #forestry company #HCHayne, then held it on behalf of the tribe. The organization worked with an alliance of tribes known as the Wabanaki Commission on Land and Stewardship, and #FirstLight, a group of non-native, land-based organizations, to secure $1.9 million for project.

" 'Indigenous land return projects are a cornerstone of our conservation efforts,' Tom Duffus, Northeast representative for The Conservation Fund, said in a statement. 'I’m thrilled that this special place is once again managed by the Mi’kmaq Nation, whose citizens have stewarded this landscape since time immemorial.'

"Mesgilg Maqamigew means 'big land,' a name chosen in recognition of the significance to the tribe of a parcel so large, contiguous and lush with resources.

"The property contains #forests, #wetlands and more than three miles of #NorthWhitneyBrook, a stream with a thriving #BrookTrout population, according to Mi’kmaq Environmental Health Director Shannon Hill.

"The tribe has already located #fiddleheads there, and Hill said they plan to use the land for #hunting, #fishing, gathering and timber. Snowmobile and ATV trails are available for public use.

"#RichardSilliboy, a basket maker and former Mi’kmaq vice chief who sits on the commission, is hopeful the parcel has #BrownAsh for weaving — but expects, at least, 'some decent fishing.'

"#MesgilgMaqamigew is the sixth to be completed in a series of projects spearheaded by the commission that are collectively known as the tributary land returns. The tributary returns comprise 52,000 acres in 11 discrete projects involving all five tribal governments in Maine at an estimated cost of $52 million."

Capped Langur Trachypithecus pileatus

Capped Langur Trachypithecus pileatus

IUCN Red List Status: Vulnerable

Location: India, Bhutan, Bangladesh, Myanmar

This species inhabits subtropical and tropical dry forests, primarily in the foothills and highlands south of the Brahmaputra River and across fragmented patches in northeastern South Asia.

The capped #langur (Trachypithecus pileatus) is a graceful and beautiful leaf #monkey found across northeastern #India, #Bhutan, #Bangladesh, and #Myanmar. Sadly, they are listed as #Vulnerable on the IUCN Red List due to rapid population declines from #deforestation, logging, agriculture, and the devastating impacts of #palmoil plantations. Once widespread, their numbers have nearly halved in some regions like Assam due to the accelerating loss of native forest cover. Directly threatened by palm oil and monoculture expansion, this species is now confined to small, isolated forest fragments. Take action every time you shop and #BoycottPalmOil #Boycott4Wildlife

The intelligent and social Capped #Langur 🙉🐒🐵 is under pressure from #palmoil #deforestation and hunting in #India 🇮🇳 Troops are interbreeding with Phayre’s #langurs to survive. Fight for them and #Boycottpalmoil 🌴☠️❌ #Boycott4Wildlife @palmoildetect https://palmoildetectives.com/2026/01/11/capped-langur-trachypithecus-pileatus/

Appearance & Behaviour

With their black-tufted crown, pale fur, and soulful eyes, capped langurs are among the most visually distinctive primates in the Eastern Himalayas. Their fur ranges from silver-grey to golden orange, with darker limbs and a black cap that gives them their name. They move gracefully through the canopy, rarely descending to the forest floor except for play or social grooming.

Capped langurs live in unimale, multifemale groups with sizes ranging from 8 to 15 individuals. They spend most of their time feeding (up to 67%) or resting (up to 40%), engaging in complex social grooming and vocal communication. Daily movements range from 320–800 metres across fragmented habitats of 21–64 hectares. Grooming is an important social activity, with females often taking turns in allomothering behaviour.

Threats

Palm oil, teak and rubber monoculture plantations

The spread of oil palm and other monoculture crops such as teak and rubber is destroying the capped langur’s native forests at an alarming rate. These industrial plantations eliminate the diverse tree species that capped langurs rely on for food and shelter, leaving them with little to survive on. Once a landscape is cleared and replaced with palm oil or other single crops, it becomes a green desert devoid of biodiversity, pushing the species closer to extinction. In regions like Assam and Bangladesh, palm oil is a major driver of habitat fragmentation and degradation, especially in forest corridors that once connected populations.

Timber deforestation

Widespread illegal logging, often fuelled by demand for timber and firewood, is rapidly eroding the capped langur’s habitat. Fruiting and lodging trees that are vital to their survival are cut down, leaving forests patchy and disconnected. As their home ranges shrink, capped langur groups are forced into smaller fragments, increasing their vulnerability to predators, food shortages, and inbreeding. In some areas, this pressure has led to local extinctions or the collapse of entire populations.

Slash-and-burn agriculture

Slash-and-burn agriculture destroys habitat for capped langurs and often brings them into closer contact with human settlements, increasing conflict and risk of hunting or roadkill. Forest recovery from this can take decades—time the capped langur simply doesn’t have.

Hunting and the illegal pet trade

Capped langurs are hunted for their meat, pelts, and for sale in the illegal pet trade. In many tribal and rural areas of Assam, Arunachal Pradesh, and Manipur, they are still targeted despite legal protections. Their pelts are used to make traditional knife sheaths, and infants are often captured after killing their mothers, then sold as pets. This exploitation causes severe suffering and has a devastating impact on group structures, leading to long-term population decline.

Roads cut into rainforests for mines and tea plantations

As forests are cut into smaller patches for roads, mining, tea plantations, and settlements, capped langur populations become increasingly isolated. Small, disconnected populations face higher risks of inbreeding, loss of genetic diversity, and eventual extinction. In some regions, such as Tinsukia and Sonitpur, populations have already disappeared due to this fragmentation. The collapse of corridors also disrupts daily movement, feeding patterns, and access to mates—placing enormous stress on surviving individuals.

Hybridisation with other species

Due to the rapid degradation of natural habitats, capped langurs are increasingly forming mixed-species groups with the closely related Phayre’s langur (Trachypithecus phayrei). Recent studies in northeast Bangladesh confirm genetically that hybridisation is occurring, which could result in the eventual cyto-nuclear extinction of the capped langur lineage. Although hybridisation can happen naturally, in this case it is being driven by human-induced fragmentation, forcing species into overlapping territories with fewer options for mates. This phenomenon is both a symptom and a driver of their decline, complicating conservation efforts.

Mining, infrastructure, and political conflict

Open-cast coal mining, limestone extraction, and petroleum exploration have all contributed to the destruction of capped langur habitat across Assam and Nagaland. Infrastructure projects, such as highways and border fences, not only destroy habitat directly but also block animal movements and isolate populations. In border regions, armed conflict and territorial skirmishes have already extirpated capped langurs from several reserves, such as the Nambhur and Rengma forests. Weak law enforcement allows habitat destruction to continue unchecked in many regions.

Geographic Range

Capped langurs are found in northeastern India (Arunachal Pradesh, Assam, Meghalaya, Nagaland, Manipur, Mizoram, and Tripura), Bhutan, northwestern Myanmar, and northeastern and central Bangladesh. They occur at elevations from 10 to 3,000 metres across hill forests, riverine reserves, and protected areas. However, their range is now severely fragmented by human development, with some populations disappearing from former strongholds due to mining, conflict, and agricultural encroachment.

Diet

Primarily folivorous, the capped langur’s diet includes mature and young leaves, petioles, seeds, flowers, bamboo shoots, bark, and occasionally caterpillars. They forage on more than 43 plant species, with favourites including banyan (Ficus benghalensis), sacred fig (Ficus religiosa), Terminalia bellerica, and Mallotus philippensis. Seasonal availability influences their feeding patterns, but they consistently prefer fruiting and flowering trees.

Mating and Reproduction

Breeding usually occurs in the dry season, with birthing concentrated between late December and May. The gestation period lasts about 200 days, and the interbirth interval is approximately two years. Only parous females participate in allomothering, allowing new mothers time to forage and recover, a behaviour rare among langurs and considered a form of altruism.

FAQs

How many capped langurs are left in the wild?

Exact numbers are uncertain, but estimates suggest the population in Assam has declined from 39,000 in 1989 to approximately 18,600 between 2008 and 2014 (Choudhury, 2014). This halving reflects habitat loss and increasing fragmentation, particularly in Upper Assam and the Barak Valley.

What is the average lifespan of a capped langur?

While data is limited, langurs of this genus generally live 20–25 years in the wild. Captive lifespans may extend slightly due to the absence of predators and constant food supply, though such conditions often lead to stress.

Why are capped langurs under threat?

Their decline is due to relentless deforestation, palm oil and monoculture plantations, illegal logging, and road-building. Slash-and-burn agriculture and mining also play a major role. Capped langurs are hunted in some regions for meat, pelts, and as pets, particularly in Assam, Arunachal Pradesh, and Nagaland.

Do capped langurs make good pets?

Absolutely not. Capped langurs are intelligent, social beings that rely on complex forest habitats and close-knit family groups. Removing them from the wild fuels extinction and causes immense trauma. Many die during illegal capture and transport. Keeping them as pets is a selfish act that destroys lives. If you care about capped langurs, never support the exotic pet trade!

What are the major conservation challenges for capped langurs?

The biggest issues are hybridisation with other primate species, habitat fragmentation, palm oil expansion, and human-wildlife conflict. The 2018 study in Satchari National Park found that local attitudes toward conservation vary by occupation, education, and gender, which means education and outreach are crucial. A big challenge is the rise in hybridisation with sympatric Phayre’s langurs, driven by habitat degradation—this poses long-term genetic risks (Ahmed et al., 2024).

Take Action!

Capped langurs are vanishing before our eyes, driven to the brink by out-of-control palm oil expansion, deforestation, and development. You can help save them.

Refuse to buy products made with palm oil. Support indigenous-led conservation in northeast India and the Eastern Himalayas.

Saola Pseudoryx nghetinhensis

Saola Pseudoryx nghetinhensis

IUCN Red List Status: Critically Endangered (CR)

Location: Vietnam and Laos

The Saola is an extremely rare #antelope species is restricted to the Annamite Mountains along the border of Laos and Vietnam. In Vietnam, they occur in Nghe An, Ha Tinh, Quang Binh, Quang Tri, Thua-Thien Hue and Quang Nam provinces. In Laos, they have been recorded in Xieng Khouang, Bolikhamxay, Khammouan, Savannakhet and Xekong provinces, generally within remote wet evergreen forests.

The elusive #Saola is one of the rarest and most mysterious animals on Earth. Described as Southeast Asia’s ‘unicorn’, this Critically Endangered #antelope is facing imminent #extinction due to indiscriminate snaring, illegal hunting, and #deforestation. No Saolas survive in captivity, and their numbers in the wild are estimated at fewer than 100. They are collateral victims of the region’s rampant #bushmeat and illegal wildlife trade, with their decline accelerated by roads, logging and expanding human access. Use your wallet as a weapon. To help the world’s rarest antelope and make sure you avoid all wildlife products, be #Vegan and choose #palmoilfree items. #BoycottPalmOil #Boycott4Wildlife

Appearance & Behaviour

The Saola is a curious looking #ungulate often described as being antelope-like in appearance, yet they are more closely related to wild cattle. They have a sleek, chocolate-brown coat, with striking white markings on the face and long, gently curved horns that can grow up to 50 centimetres for both sexes. These parallel horns have earned them the nickname the ‘Asian Unicorn.’

Highly secretive and shy, Saolas are rarely seen even by local indigenous people, and much of what we know comes from a handful of camera-trap images and village interviews. Saolas are solitary ungulates or found in small groups and may use scent glands to mark their territories. Saolas appear to favour lower altitudes during the dry season and may migrate with seasonal changes in water and vegetation.

Threats

Widespread snaring and indiscriminate hunting

The primary threat to Saola survival is indiscriminate snaring across their forest habitat. These wire snares are set to catch a variety of animals like wild pigs, civets and muntjacs, but Saolas are frequently caught as bycatch. Because Saolas are not specifically targeted, their deaths often go unnoticed or unreported. The sheer density of snares—sometimes thousands per square kilometre—means that even extremely rare species like the Saola are at constant risk of entrapment.

Bushmeat and traditional medicine trade

Despite not being valued specifically for their meat or body parts, Saolas are still victims of Southeast Asia’s booming wildlife trade. They are often killed and consumed locally or caught up in snares set for animals more widely traded or consumed for bushmeat and medicinal purposes. The expansion of disposable income and demand for wild meat and medicinal wildlife products in Vietnam and China is driving this crisis. Villagers report a sharp drop in sightings, indicating Saolas are being wiped out as collateral damage in this unregulated trade.

Road construction and increased human access

The rapid expansion of roads such as the Ho Chi Minh Road and the East-West Economic Corridor has fragmented Saola habitat and created unprecedented access for poachers. These roads allow motorbikes and trucks to transport wildlife quickly to urban markets, making illegal hunting more efficient. The increased accessibility also brings in thousands of forest product collectors who opportunistically snare wildlife. Road development directly and indirectly fuels the extinction of Saolas by opening up remote refuges once safe from exploitation.

Deforestation for monocultures like palm oil

Although hunting is the most immediate threat, habitat loss is an intensifying danger due to shifting agriculture, logging, mining and hydropower development. The Annamite forests are being carved up into ever smaller fragments, making it harder for Saola populations to remain connected. Forest blocks under 100 km² are likely uninhabitable for Saolas, who depend on large tracts of wet evergreen forest with low human disturbance. As development pressures mount, remaining habitat is also degraded by noise, pollution and human presence.

Ineffective protected area management

While Saolas occur in several designated protected areas, most of these offer little real protection from hunting. Enforcement is weak or absent, and many parks are under pressure from the same road construction and development projects that threaten unprotected forests. In some cases, protected areas themselves have become conduits for illegal activities like poaching and logging. Without strong enforcement and dedicated anti-snare patrols, protected status does little to ensure Saola survival.

Population isolation and low genetic diversity

Saola populations are now so small and fragmented that individuals may be isolated from one another for breeding. The species’ naturally low densities and secretive behaviour are further compounded by habitat fragmentation and snaring. This isolation increases the risk of inbreeding and local extinctions. If individuals can no longer find mates or suitable territory, the population could collapse without ever being noticed.

Climate and ecological constraints

Saolas are highly specialised to wet evergreen forests, which are rare and shrinking. Their apparent absence from degraded or secondary forests suggests they may be intolerant of even moderate ecological change. Unlike more adaptable species such as pigs or muntjacs, Saolas do not seem able to survive in altered landscapes. As climate patterns shift and dry seasons become more severe, even their last refuges may become inhospitable.

Rising wealth fuelling wildlife demand

Contrary to assumptions that poverty drives biodiversity loss, it is rising wealth and urban demand that most endanger Saolas. Affluent consumers in Vietnam and China are fuelling the demand for exotic meats and traditional medicine, spurring illegal hunting. The status-driven consumption of wildlife products—rather than subsistence need—is a primary force behind the escalating poaching crisis. Until demand is curbed at the source, rare species like the Saola will continue to vanish.

Geographic Range

The Saola is found exclusively in the Annamite Mountains along the border of Laos and Vietnam. In Vietnam, they are recorded from Nghe An to Quang Nam provinces. In Laos, they occur in Xieng Khouang, Bolikhamxay, Khammouan, Savannakhet and Xekong provinces.

Their historical range has shrunk drastically, and they are now believed to be confined to fewer than 10 forest blocks, with an estimated area of occupancy likely under 1,000 km². They are absent from small forest fragments and likely restricted to remote, difficult-to-access areas with lower hunting pressure.

Diet

The Saola is a #herbivore and a browser, feeding mainly on tender leaves, shoots, and possibly fruit. Their diet likely consists of foliage from forest understorey plants, but detailed studies are lacking due to the species’ extreme rarity and secretive nature.

Mating and Reproduction

Very little is known about Saola reproduction. Local reports suggest they give birth to a single calf, and births may occur in the summer. Their generation time is thought to be longer than that of sympatric species like muntjacs or pigs, with lower reproductive output. No captive births have ever occurred.

FAQs

How many Saolas are left in the wild?

Estimates suggest there are fewer than 100 individuals remaining in the wild, with a likely number of under 250 mature individuals (IUCN SSC, 2020). No confirmed sightings have occurred since 2013, and the vast majority of reports come from indirect sources such as camera traps or local accounts.

Do Saolas make good pets?

Absolutely not. Saolas are wild, elusive, and cannot survive in captivity. Every individual removed from the wild brings them closer to extinction. Keeping or capturing Saolas is illegal and a direct threat to their survival.

Why are Saolas so rare?

Saolas are not specifically targeted, but they are frequent victims of indiscriminate snaring, which is widespread in their range. The pressure from hunting is compounded by habitat fragmentation, road construction, and increased human encroachment, leaving them with few undisturbed refuges.

What is being done to protect Saolas?

Efforts include the Saola Working Group’s use of camera traps, dung analysis and local knowledge to pinpoint remaining populations. Conservationists are advocating for snare-removal programmes and more effective protected area management, but without a captive breeding programme or large-scale investment, Saolas remain perilously close to extinction (Wilkinson & Duc, 2016).

What type of forest do Saolas live in?

They are found in wet evergreen forests with minimal dry season, primarily on the Vietnamese slopes of the Annamite Mountains. These habitats are cooler, cloud-covered and have high year-round rainfall, creating a niche Saolas are uniquely adapted to. Unfortunately, such habitats are increasingly fragmented and degraded.

Take Action!

Saolas are being driven to extinction by snares and the relentless pursuit of wild meat and medicine. Every product you buy that contributes to forest loss—like those made with palm oil—accelerates their disappearance. Support local communities leading conservation efforts in Vietnam and Laos.

Tucuxi Sotalia fluviatilis

IUCN Red List Status: Endangered

Location: #Brazil, #Peru, #Colombia, #Ecuador

Found throughout the #Amazon and Solimões River systems, including major tributaries and large lakes. Their range spans lowland rainforest areas of Brazil, southeastern Colombia, eastern Ecuador, and southern Peru.

The #Tucuxi, a small freshwater #dolphin of #Peru, #Ecuador, #Colombia and #Brazil now faces a dire future. Once common throughout the Amazon River system, they are now listed as #Endangered due to accelerating population declines. Threats include drowning in fishing nets, deforestation, mercury poisoning from gold mining, #palmoil run-off, oil drilling, and dam construction. A shocking 97% decline was recorded over 23 years in a single Amazon reserve. Without urgent action, this elegant and playful river dolphin could vanish from South America’s waterways.

Appearance & Behaviour

Tucuxis are often mistaken for their oceanic dolphin cousins due to their streamlined bodies, short beaks, and smooth, pale-to-dark grey skin. But these freshwater dolphins are wholly unique—adapted to life in winding river systems where water levels rise and fall dramatically with the seasons.

What sets them apart is their remarkable intelligence and tightly knit social groups. Tucuxis are playful and curious by nature. They leap from the water in graceful arcs, sometimes spinning mid-air.

The Tucuxi, sometimes called the ‘grey dolphin’ due to their uniform colouring, resembles a smaller oceanic dolphin, with a streamlined body and slender beak. Their colour varies from pale grey on the belly to darker grey or bluish-grey along the back.

They travel in small groups of two to six, displaying coordinated swimming patterns. In rare cases, they may form groups up to 26 individuals, particularly at river confluences. Known for their agility, they leap and spin in the water with a grace that belies their size. Tucuxis are particularly drawn to dynamic habitats like river junctions, where waters mix and fish gather.

Threats

• Widespread deforestation from palm oil plantations Palm oil plantations are rapidly expanding across the Amazon, clearing vast tracts of forest that stabilise riverbanks and filter water. This deforestation leads to increased sedimentation in rivers, altering flow patterns and reducing water clarity—conditions that directly disrupt the Tucuxi’s feeding and movement. Run-off from fertilisers and pesticides used in palm oil monocultures also poisons aquatic ecosystems, harming Tucuxis other Amazonian dolphin species and the fish they rely on.
• Toxic mercury pollution from gold mining Artisanal and illegal gold mining in the Amazon releases massive quantities of mercury into the water, contaminating fish and other aquatic organisms. Tucuxis, as top predators, ingest this mercury through their prey, which accumulates in their tissues and causes neurological damage, weakened immunity, and reproductive failure. Mercury exposure is one of the most insidious threats, as it persists in ecosystems long after mining has ceased.
• Incidental drowning in fishing nets Tucuxis are frequently caught and killed in gillnets and other fishing gear as bycatch. Tucuxis and other Amazonian dolphins often inhabit the same confluence zones and productive fishing grounds targeted by local communities, making entanglement almost inevitable. Many carcasses are never recovered, having either been discarded by fishers or lost to river currents, meaning actual mortality rates are likely far higher than reported.
• Deliberate hunting for use as fish bait Though illegal, Tucuxis continue to be targeted and killed in parts of Brazil, especially near the Mamirauá and Amana Reserves, where they are used as bait in the piracatinga (catfish) fishery. This brutal practice involves harpooning or netting dolphins and using their flesh to lure fish, often alongside the killing of Botos. Despite a national ban, weak enforcement and ongoing demand mean this threat persists in remote and lawless regions.
• Illegal fishing with explosives and toxins In certain areas, particularly in Brazil and Peru, fishers use home-made explosives and poisoned bait to stun or kill fish en masse. These destructive methods harm or kill Tucuxis who are attracted by the sudden appearance of dead or stunned prey. The concussive force of explosions and the ingestion of poisoned prey result in slow, agonising deaths for affected dolphins.
• Construction of hydroelectric dams Dams fragment Tucuxi populations by blocking their movement along river corridors, reducing access to feeding and breeding grounds. These projects alter seasonal water flow, raise water temperatures, and flood critical habitats—conditions that significantly disrupt dolphin ecology. Brazil alone has 74 operational dams in the Amazon basin, with over 400 more planned, posing a long-term existential threat to freshwater cetaceans.
• Run-off and contamination from palm oil, soy and meat agriculture In addition to habitat loss, palm oil and soy plantations along with cattle ranching generates enormous volumes of chemical-laden waste, which enters waterways and poisons aquatic life. This pollution affects Tucuxis both directly and indirectly—exposing them to harmful substances and killing off sensitive fish species. As plantations replace biodiverse forests, the ecosystem becomes less resilient, accelerating the decline of species like the Tucuxi.
• Bioaccumulation of heavy metals and industrial pollutants Tucuxis, like many river dolphins, suffer from exposure to persistent organic pollutants such as PCBs, DDT, and flame retardants, as well as heavy metals like lead and cadmium. These toxins accumulate in dolphin tissues over time, weakening their immune systems, interfering with reproduction, and making them more vulnerable to disease. Contaminants originate from industrial waste, agriculture, and mining, and are now widespread across the Amazon basin.
• Habitat fragmentation from infrastructure and oil development Roads, oil pipelines, and shipping corridors criss-cross many parts of the Tucuxi’s range, slicing through their habitat and increasing the risk of collisions with boats. These developments also bring noise pollution, which can interfere with echolocation and communication. Fragmentation leads to isolated subpopulations, reducing genetic diversity and making recovery more difficult.

Geographic Range

The Tucuxi inhabits the Amazon River basin, spanning: Brazil, Peru, Colombia, Ecuador These river dolphins occur as far west as southern Peru and eastern Ecuador, and as far north as southeastern Colombia. They are notably absent from Bolivia’s Beni/Mamoré system, the Orinoco basin, and upper reaches above major waterfalls or rapids.

Their range includes wide, deep rivers and lakes, avoiding turbulent rapids and shallow areas. Despite overlapping with the Amazon River Dolphin (Inia geoffrensis), Tucuxis do not enter flooded forest habitats and stay closer to main river channels.

Diet

Tucuxis feed on more than 28 species of small, schooling freshwater fish, including members of the characid, sciaenid, and siluriform families. During the dry season, fish are concentrated in shrinking waterways, making them easier to catch. In contrast, flooding season disperses prey into forested areas, beyond the Tucuxi’s reach. They prefer to feed at river junctions and along confluences, where nutrient-rich waters concentrate fish populations.

Mating and Reproduction

Little is known about their mating behaviours. However, individuals appear to remain within familiar ranges for many years, and females likely give birth to a single calf after a long gestation. Calves are dependent for an extended period, learning complex navigation and foraging skills in rapidly changing river systems. The estimated generation length is 15.6 years.

FAQs

How many Tucuxis are left in the wild?

There is no comprehensive global population estimate. However, surveys from 1994–2017 in Brazil’s Mamirauá Reserve show a 7.4% annual decline—amounting to a 97% drop over three generations (da Silva et al., 2020). If this trend reflects the wider Amazon basin, the species could be on the brink of collapse.

How long do Tucuxis live?

Exact lifespans are unknown, but based on reproductive data and life history modelling, their generation length is around 15.6 years (Taylor et al., 2007), suggesting natural lifespans of 30–40 years.

How are palm oil and gold mining affecting Tucuxis?

Out-of-control palm oil expansion results in massive deforestation and run-off, clogging rivers with sediment and toxic agrochemicals. Gold mining adds mercury into aquatic ecosystems, where it bioaccumulates in fish—Tucuxis’ main food source. These pollutants cause reproductive harm, neurological damage, and immune system failure in dolphins.

Do Tucuxis make good pets and should they be kept in zoos?

Absolutely not. Tucuxis are intelligent, wild animals. Keeping them in captivity is deeply cruel and has no conservation benefit. Wild capture destroys families and can devastate local populations. If you care about these dolphins, say no to the exotic pet trade and the cruel zoo trade.

What habitats do they prefer?

Research in Peru’s Pacaya-Samiria Reserve shows that Tucuxis prefer river confluences and wide channels, particularly during the dry season when fish density is higher (Belanger et al., 2022). Feeding activity is especially concentrated in areas where whitewater rivers meet blackwater tributaries, creating nutrient-rich hotspots.

Take Action!

The Tucuxi is vanishing before our eyes. To protect them:

• Boycott palm oil and gold products linked to Amazon destruction.

• Choose fish-free and vegan products to reduce pressure on river ecosystems.

• Support indigenous-led conservation across the Amazon.

• Campaign for a ban on destructive dams, and the end of illegal fishing.

Ecuadorean Viscacha Lagidium ahuacaense

Ecuadorean Viscacha Lagidium ahuacaense

IUCN Status: Critically Endangered

Location: Ecuador’s Cerro El Ahuaca

High in the remote granite outcrops of Cerro El Ahuaca, #Ecuador the Ecuadorean #Viscacha Lagidium ahuacaense is plump and fluffy #rodent sporting sage-like long whiskers. From their high perch they look down upon the world below with a permanent expression of what could interpreted as disappointment. Ecuadorean Viscachas were first spotted in 2005 and formally described in 2009, these mountain-dwelling large #rodents are the northernmost member of the Lagidium genus, marooned over 500 kilometres from their closest relatives in #Peru. Few creatures are as elusive or fascinating— tragically, only a handful of them remain alive.

Fires, #beef agriculture, and #deforestation for monoculture are carving away at their already fragile existence, pushing them ever closer to the brink of #extinction. Help them by sharing their story to social media. Join the #Boycott4Wildlife.

Appearance & Behaviour

Built for survival in one of Ecuador’s harshest landscapes, the Ecuadorean Viscacha is a sturdy and big rodent with a compact body covered in thick, grey-brown fur. Their dense, woolly fur shields them from the biting Andean winds, while their long, silvery tails provide balance as they scale sheer rock faces. Their large, dark eyes scan the terrain for danger, and their long, sensitive whiskers twitch as they pick up the faintest vibrations in the wind.

Long and distinguished whiskers provide them with sensitive and deep understanding of their environment. A black dorsal stripe runs the length of their back, this disappears into the dense coat that keeps them warm against the mountain’s chill.

Most active at dawn and dusk, their every movement is deliberate. They bound effortlessly between jagged outcrops, using their powerful hind legs to launch themselves across treacherous gaps. Unlike burrowing rodents, they take refuge in narrow rock crevices, where they remain hidden from predators.

Threats

Once secure in their isolated stronghold, the Ecuadorean Viscacha now faces a gauntlet of human-driven threats. Their already tiny population is being squeezed into an ever-smaller fragment of land, where survival is becoming increasingly precarious.

Deforestation for eucalyptus and pine monoculture plantations

For generations, wildfires have been used to clear land for agriculture and livestock grazing, but in recent decades, these fires have intensified, spreading further into the Viscacha’s habitat. Each blaze devours critical vegetation, stripping away the food sources they rely on and forcing them into ever-smaller pockets of surviving habitat.

Farmed Animal Agriculture

Grazing cattle have become an unrelenting force in the region, trampling vegetation and outcompeting the Viscacha for food. Their presence has disrupted the delicate balance of this fragile ecosystem, leaving fewer resources for native wildlife.

Climate Change-related Environmental Shifts

With their entire known population confined to a single mountain, the Ecuadorean Viscacha is especially vulnerable to even the smallest environmental shifts. Changing rainfall patterns, prolonged droughts, and temperature fluctuations could alter the availability of food and water, placing further stress on their already limited numbers.

Population Fragmentation and Isolation

Trapped within a tiny range with no known neighbouring populations, the Viscacha is cut off from potential mates and genetic diversity. Without intervention, this isolation could lead to inbreeding, weakening the species’ ability to adapt and survive.

Geographic Range

The Ecuadorean Viscacha is found only in a single location—Cerro El Ahuaca, a rugged granite mountain in southern Ecuador. They inhabit steep, rocky surfaces at elevations between 1,950 and 2,480 metres, a world of exposed rock faces and sparse vegetation. No other known populations exist, making them one of the most geographically restricted mammals on the planet.

Though their habitat once stretched further, fires and deforestation have steadily chipped away at the fringes of their territory. Today, their entire known range spans just 120 hectares—an area smaller than many urban parks—leaving them with little room to escape the pressures of a changing world.

Diet

These high-altitude specialists are herbivores, feeding primarily on native grasses, shrubs, and small herbs that cling to the mountainside. Signs of their feeding are visible throughout their habitat—freshly grazed plants and stripped vegetation mark the places where they have foraged. Their diet is shaped by scarcity, forcing them to survive on whatever plant life they can find in their isolated, rocky home. Their close relatives Mountain Viscacha of Peru are preyed upon by Andean Mountain Cats.

Mating and Reproduction

Little is known about the reproductive habits of the Ecuadorean Viscacha, but they likely follow a pattern similar to their relatives in the Lagidium genus. Mountain Viscachas generally give birth to a single offspring after a long gestation period, ensuring that each newborn has a better chance of survival in the unforgiving terrain. Born with fur and open eyes, young Viscachas are relatively well-developed, an adaptation that allows them to quickly learn the skills needed to navigate their hazardous mountain environment.

FAQs

Are Ecuadorean Viscachas related to rabbits or chinchillas?

Despite their rabbit-like appearance, Ecuadorean Viscachas belong to the Chinchillidae family, making them closer relatives of chinchillas than rabbits. Their long whiskers, dense fur, and powerful hind legs are adaptations seen in other members of this family, allowing them to thrive in rocky, high-altitude environments.

How are Ecuadorean Viscachas different from other Mountain Viscachas?

Ecuadorean Viscachas are the northernmost species of the Lagidium genus, separated by more than 500 kilometres from their closest relatives in Peru. Genetic studies show that they diverged significantly from other Mountain Viscachas, with at least 7.9% DNA sequence differences. Morphologically, they have a more compact body, a distinct black dorsal stripe, and a tail that shifts in colour from grey-brown to reddish-brown. Their isolation and unique adaptations to the Cerro El Ahuaca environment make them a distinct species.

How do Ecuadorean Viscachas survive in their rocky habitat?

Perfectly adapted to life among sheer cliffs and granite outcrops, Ecuadorean Viscachas use their powerful hind legs to leap between rocks, navigating the treacherous terrain with ease. Their thick, woolly fur provides insulation against the cold, and instead of burrowing, they take refuge in rock crevices where they remain hidden from predators.

What do Ecuadorean Viscachas eat?

These herbivores feed on native shrubs, grasses, and small herbs found in their mountainous habitat. They leave behind distinct feeding traces, such as grazed vegetation and stripped plants, which provide insight into their foraging habits. Their diet is dictated by the limited plant life available in their isolated environment.

How many Ecuadorean Viscachas are left in the wild?

The total known population is alarmingly small, possibly consisting of only a few dozen individuals confined to a 120-hectare area on Cerro El Ahuaca. No other populations have been discovered, making them one of the most critically endangered rodents in the world.

What are the biggest threats to the Ecuadorean Viscacha?

Their biggest threats include:

• Habitat destruction – Uncontrolled fires and land clearing for eucalyptus and pine monoculture and cattle grazing are steadily erasing their already limited habitat.

• Livestock competition – Grazing cattle trample vegetation and outcompete Viscachas for food.

• Climate change – Shifting rainfall patterns and temperature fluctuations could further disrupt their delicate ecosystem.

• Genetic isolation – With only a single known population, they face the risk of inbreeding, which could weaken their resilience.

Why are they only found in one place?

Ecuadorean Viscachas are highly specialised mountain dwellers, perfectly suited to the rocky terrain of Cerro El Ahuaca. They may have once had a wider range, but habitat destruction and fragmentation have left them stranded in this isolated stronghold. Unlike more adaptable rodents, they cannot easily move to new areas due to their specific habitat needs.

Are Ecuadorean Viscachas protected?

The Ecuadorean Vischaca was only recently discovered and are considered a forgotten species. However conservation efforts have begun, there is no targeted species-wide protection in place. However, local conservation initiatives have helped establish protected areas that include their habitat. Researchers continue to push for stronger conservation measures to ensure their survival.

How can I help save the Ecuadorean Viscacha?

You can make a difference by:

• Supporting conservation organisations working to protect their habitat.

• Raising awareness about the threats they face by sharing this post and joining the #Boycott4Wildlife

• Advocating for stronger environmental policies in Ecuador to prevent further deforestation and habitat loss.

Without immediate action, these rare and remarkable mountain survivors could disappear forever.

Take Action!

The Ecuadorean Viscacha is teetering on the edge of extinction, but there is still time to act. Conservationists have already taken steps to protect their habitat, securing key areas under municipal conservation agreements. However, long-term survival depends on preventing further destruction of their fragile mountain refuge.

You can help by:

• Supporting organisations working to protect Ecuador’s high-altitude ecosystems.

• Spreading awareness about the threats facing the Ecuadorean Viscacha and the urgent need for conservation.

• Demanding stronger environmental protections to prevent further habitat loss in Loja Province.

Every effort counts. Without immediate action, these extraordinary mountain survivors could disappear forever.

Encountering the World’s Most Endangered Kangaroo: The Wondiwoi Tree Kangaroo

Encountering the Wondiwoi tree kangaroo, the world’s most endangered kangaroo, in West Papua’s lush forests is a bittersweet tale. Rediscovered in 2018 by British botanist Michael Smith, this rarest kangaroo, with soulful eyes and burnt umber fur, symbolises tranquillity amidst severe threats like palm oil deforestation and hunting. Less than 50 kangaroos remain alive, underscoring the urgent need for conservation efforts prioritising indigenous sovereignty. To help save these remarkable creatures, join the #Boycottpalmoil and #Boycott4Wildlife and take action via this website.

A Bittersweet Rediscovery of the Rarest Kangaroo Alive

In the dense, emerald heart of the Wondiwoi Mountains, in West Papua the trees echo with the haunting refrains of the vogelkop superb bird-of-paradise. Underfoot, the ground is soggy and dense with mossy herbaceous fragrances and the scuttling of an eastern long-beaked echidna as she burrows into her subterranean domain. In 2018, an extraordinary moment was captured forever on camera in 2018. High in the treetops, amidst the thick moss-covered branches, a shy Wondiwoi tree kangaroo lay in quiet repose, a symbol of sturdy, plump beauty. This creature was believed to be extinct for nearly a century. Yet a chance encounter by British amateur botanist Michael Smith in 2018 has thrust this creature back into the spotlight.

Wondiwoi tree kangaroos Dendrolagus mayri have an odd combination of kangaroo and monkey qualities. Large and soulful eyes blink from behind long eyelashes and thickly furred paddle-like arms culminate in strong sharp claws fit for grasping tree branches. Their bodies are the colour of burnt umber and terracotta and embody the tranquillity of Papua’s majestic montane forests where they blend into the painter’s palette of the jungle.

Smith’s serendipitous discovery of Wondiwoi tree kangaroos, known as the world’s rarest and most endangered kangaroo, highlights their precarious existence due to human-related threats like palm oil deforestation, rare mineral mining and hunting throughout their range.

A Journey Fuelled by Passion and Curiosity

Michael Smith is an amateur botanist from England. He spends a lot of his free time traversing remote locations like Indonesia, Pakistan and Kurdistan in the faint hope of encountering the rarest species on earth.

“I want these animals to be the poster children for seriously threatened and ancient habitats. I’m trying to get evidence of something interesting – and in terms of getting people involved and excited about conservation, it seems to be effective.”

Michael Smith, interview in the Guardian, 2023.

He understands that time is of the essence to save these animals and many others from the relentless growth of palm oil deforestation.

It’s hard to know if things will change fast enough for there to be anything left. In the 1990s, Papua New Guinea was just a big forest, with a few people. Now it’s still 80% or 90% forest, but there is huge pressure from people and investors who want to make palm oil.” 

Michael Smith, interview in the Guardian, 2023.

The Enigmatic Wondiwoi Tree Kangaroo

The bittersweet rediscovery of the Wondiwoi tree kangaroo underscores their gravely precarious position as the rarest kangaroo in the world. Originally they were discovered in 1928 by Ernst Mayer and known only by a single specimen. Papuan non-profit Tenkile Conservation Alliance estimates that less than 50 individuals remain alive.

The Wondiwoi tree kangaroo’s habitat is under severe threat from palm oil deforestation and the extraction of rare minerals such as mica and gold. The forests of West Papua, once a haven for diverse wildlife, are being decimated in silence.

The Guardians of the Forest

The survival of the Wondiwoi tree kangaroo is intricately linked to the sovereignty, and land stewardship of the Papuan indigenous peoples. Their deep spiritual and ancestral connection to the land and its human and more-than-human inhabitants stands in stark contrast to the destructive policies of the colonialist Indonesian government. Conservation efforts must prioritise indigenous rights and knowledge, recognising that true protection of these animals lies in the hands of those who have lived in harmony with the forest for many millennia.

Tenkile Conservation Alliance have a range of programmes helping indigenous peoples to understand the importance of conserving rather than hunting tree kangaroos and providing them with ways to harvest alternative sources of food. They have developed tree kangaroo hunting moratoriums as well alongside village communities.

The Jungle Kingdom of Dendrolagus: Tree Kangaroos

The genus Dendrolagus, more enchantingly known as tree kangaroos, embody arboreal grace and irresistible chubby cuteness. These marsupials are lesser known than their iconic ground-dwelling cousins further south in Australia and possess a range of distinctive traits making them masters of the jungle canopy.

Their exceptionally long, pendulous tails act as elegant counterbalances, helping with every leap and bound. Strong forelimbs, paired with shorter and broader hind feet, provide them with superior strength and agility. Long curved claws and spongy paws enhance grip, like natural bouldering shoes, allowing them to climb and cling effortlessly to branches.

Females possess a forward-opening pouch (marsupium) containing four teats. These provide a nurturing haven for their developing young. Their teeth are adapted for shearing leaves, reveal their dietary preference for the verdant foliage of the treetops.

The almost ‘bears’ and barely there Dendrolagus genus:

• Doria’s Tree Kangaroo Dendrolagus dorianus: With their robust build and dark brown fur and are listed as Vulnerable on the IUCN Red List. Learn more.
• Lowlands Tree Kangaroo Dendrolagus spadix: Known for their reddish-brown fur, gentle demeanour andd striking striped tails, these kangaroos are also listed as Vulnerable. Learn more.

• Grizzled Tree Kangaroo Dendrolagus inustus: Distinguished by their grey fur and gentle eyes, these kangaroos are classed as vulnerable. Learn more.

Taking Action: How You Can Help

The rediscovery of the Wondiwoi tree kangaroo underscores the urgent need for consumer action. Here’s how you can make a difference:

1. Boycott Palm Oil: Reject RSPO greenwashing and avoid products containing “sustainable” palm oil. Use your purchasing power to demand palm oil free in the supermarket. Join the #Boycottpalmoil and #Boycott4Wildlife movement on social media.
2. Raise Awareness: Share posts on social media and engage in supermarket sleuthing to expose brands that use palm oil. Highlight the ongoing deforestation and animal cruelty.
3. Support Indigenous Sovereignty: Advocate for the rights and sovereignty of Papuan indigenous peoples, recognising their crucial role in conserving rainforest habitats and as guardians of rare species.
4. Donate: Support the ongoing advocacy of Palm Oil Detectives and the non-profit Tenkile Conservation Alliance, who work tirelessly to protect indigenous peoples, endangered species and their environments.
5. Get Involved: Participate in local and global conservation efforts. Whether through social media activism, community education, or direct action, every effort counts.

By taking these steps, you can help ensure that the Wondiwoi tree kangaroo and other endangered species in Papua have a fighting chance to survive and thrive.

The fight to protect the Wondiwoi tree kangaroo is a testament to the resilience of nature and the enduring spirit of people all over the world who strive to safeguard it. Together, we can shine a light on the darkness of deforestation and exploitation, ensuring a brighter future for these remarkable creatures and their forest home.

Bougainville Monkey-faced Bat Pteralopex anceps

Red List Status: Endangered

Extant (resident): Papua New Guinea; Solomon Islands

In the verdant, high-altitude forests of Bougainville Island, Papua New Guinea, and Choiseul Island, Solomon Islands, lives an intriguing creature—the Bougainville Monkey-faced bat or, as some call them, the Bougainville Flying Monkey. These bats are the titans of their family, boasting arm spans stretching impressively between 14.1 to 16 cm. They are endangered, mostly from palm oil and gold mining deforestation and hunting. Help them to survive every time you shop and #Boycottpalmoil #Boycott4Wildlife

Appearance & Behaviour

During the night time, their captivating eyes that glow red or orange under the night sky, much like their kin.

They wear a mantle of thick, black fur that shrouds their heads and backs, whilst a contrasting splash of white or yellow graces their chests, making them a sight to behold. Unlike their relatives, the Guadalcanal Monkey-faced bats, their legs are enshrouded with a full coat of fur. During the night time, their captivating eyes that glow red or orange under the night sky, much like their kin. Tailless and intriguingly equal in size whether male or female, these bats certainly stand out in the animal kingdom.

Threats

Habitat Destruction:

• Bougainville Monkey-faced bats predominantly depend on mature, upland forests.
• Significant habitat destruction from agricultural activities and forest conversion.

Hunting Pressures

• They are regularly hunted for bushmeat: Hunting practices often involve burning the bats’ roosting trees, thereby destroying their habitats.
• Increased hunting pressure was partly due to civil tensions in Bougainville from 1987 to 2000.

Population Decline:

• Bougainville Monkey-faced bats were feared extinct in 1992 due to a lack of sightings.
• Tragically, their population is estimated to have declined by at least 50% from 1997-2017.
• Despite suggestions for a captive breeding program in 1992 to curb population decline, no such program exists as of 2017.

Conservation Efforts:

Bougainville Monkey-faced bats are listed as an Endangered species on the IUCN Red List. Bat Conservation International included them in its worldwide priority list for conservation in 2013.

Conservation strategies involve collaborations with local communities and organisations, identifying alternative protein sources, reforestation, managing conflicts between the bats and farmers, and promoting conservation dialogue.

Habitat

Found high above sea level in cloud forests over 1,100 metres, the Bougainville Monkey-faced bat enjoys the tranquillity and freshness of higher altitudes. After vanishing from sight on Bougainville Island since 1968, they made a surprise reappearance in 2016. On Choiseul Island, though, they’ve been conspicuously absent since 2008. These bats have a penchant for mature, highland tropical forests and aren’t picky about roosting spots, be it in hollow trees or hanging off fig tree branches. There’s even talk about these bats gouging trees for sap—a unique adaptation indeed!

Diet

While the exact diet of these bats remains a mystery, the significant wear on the teeth of museum specimens provides a clue. This condition points to the possibility of them consuming hard, rough-textured fruits.

Mating and breeding

Many aspects of the biology and behaviour of this bat, like many other megabats, remain understudied due to their inaccessible habitats and their elusive, secretive natures.

Sunda #pangolins, also known as the Malayan or Javan pangolins, possess quirky traits that make them truly intriguing. They are capable swimmers and have a remarkable defense mechanism of curling into a protective ball, walk in an upside-down manner, and communicate through scale vibrations. As consummate insectivores, they rely on their long, sticky tongues to extract ants and termites from mounds. These pangolins have a slow metabolism, lack teeth but have a gizzard-like structure, and feature a specialised digestive system. To protect these unique creatures and their habitat, it’s crucial to take action. Join the movement and raise awareness about their primary threat #poaching and also by boycotting palm oil, which is also contributing towards their demise and putting them at risk of extinction.

Sunda pangolins use a fascinating behaviour called “scale vibrations” to communicate with each other. By contracting and relaxing their muscles, they create subtle vibrations that can be sensed by other pangolins through their scales. These vibrations likely play a role in social interactions and mate selection.

Appearance & Behaviour

Here are some quirky facts about Sunda Pangolins which demonstrate their reign as one of the most fascinating creatures in the entire animal kingdom:

• Walking on the ceiling: Sunda pangolins have an interesting way of moving about. When they are on the ground, they walk on their hind legs with their forelimbs curled upwards. This peculiar method of locomotion is commonly referred to as the “upside-down walk.”
• Defensive and protective curl: When Sunda pangolins feel threatened, they have a unique defense mechanism. They curl up into a tight ball, using their scales as a protective armor. This posture makes it incredibly challenging for predators to attack them effectively.
• Consummate Insectivores: Sunda pangolins have an exceptionally specialised diet. They are insectivores, primarily feeding on ants and termites. Their long, sticky tongues, which can be longer than their body length, allow them to probe deep into termite mounds and anthills to extract their prey.
• Their scales vibrate: Sunda pangolins use a fascinating behaviour called “scale vibrations” to communicate with each other. By contracting and relaxing their muscles, they create subtle vibrations that can be sensed by other pangolins through their scales. These vibrations likely play a role in social interactions and mate selection.
• They have no teeth: Unlike most #mammals, Sunda pangolins lack teeth. However, they possess a muscular stomach and a unique adaptation known as a gizzard-like structure. They swallow small stones or grit, which aids in grinding up their insect prey within the digestive system.
• They have a slow Metabolism: Sunda pangolins have a relatively slow metabolism, which contributes to their low energy requirements. This metabolic trait allows them to survive on a diet consisting mainly of insects, which provide them with the necessary nutrients and energy.
• Their unusual digestive system: The digestive system of Sunda pangolins is adapted to handle their specialised diet. It features a long and complex intestine to maximize nutrient absorption, enabling them to extract as many nutrients as possible from the insects they consume.

Threats

Sunda Pangolins are heavily threatened and are now critically endangered. Their main threat is from hunting and poaching for local and international use. Their secondary threat is habitat destruction across their range for palm oil, timber and other crops.

• Demand comes from China and Vietnam: this drives the illegal trade in poaching, involving large quantities of live and dead animals, meat, and scales. Sophisticated trade routes exist over land and sea, contributing to the decline of Sunda Pangolin populations.
• Palm oil deforestation in Indonesia and Malaysia: accelerates poaching with increased access to animals from deforestation activities.
• Indonesia is a major source of illegal exports: involving live pangolins and meat, especially since 2000.
• Pangolin meat is consumed as a luxury product: in high-end urban restaurants, and scales are used in traditional medicine.
• Illegal trade is supported by insufficient legal protection in SE Asia.
• Snaring, accidental mortality, and injuries pose risks due to pervasive hunting practices in South East Asia.

Take action to protect the Sunda Pangolin and their habitat and #Boycottpalmoil #Boycott4Wildlife in the supermarket.

Habitat

Sunda pangolins (Manis javanica) are found across Southeast Asia. Their range includes countries such as Myanmar, Thailand, Cambodia, Laos, Malaysia, Singapore, Vietnam, and the islands of Borneo, Java, Sumatra, and the Lesser Sunda Islands.

In terms of habitat, Sunda pangolins prefer forested environments, including primary, secondary, and scrub forests. They can also be found in plantations such as rubber and palm oil plantations. These pangolins have adapted to spend a significant portion of their lives in trees, making use of their prehensile tails for climbing.

Diet

Sunda pangolins primarily feed on ants and termites, making them insectivores. Their diet consists mainly of these small invertebrates. They use their long, sticky tongues to probe into termite mounds and ant hills, collecting the insects as their main source of sustenance. The lack of teeth in pangolins is compensated by their specialised tongues and digestive system, which are well-adapted to consuming large amounts of ants and termites. This diet of ants and termites provides the necessary nutrients and energy for Sunda pangolins to thrive in their natural habitats.

Mating and breeding

Pangolins are fascinating creatures that give birth to one or two offspring annually. Their breeding season takes place in autumn, and females carefully select winter burrows where they give birth. They prefer mature forest tree hollows for added fortification and stability during the birthing and nurturing process.

Parental care lasts for about three months, during which the mother’s range significantly decreases as she travels and forages alongside her young. Only in the weeks before the offspring becomes independent, brief bursts of diurnal activity may be observed. Pangolins are typically solitary and nocturnal, using their ability to roll into protective balls to safeguard their vulnerable underparts when feeling threatened.

They are skilled diggers, creating burrows lined with vegetation near termite mounds and ant nests for insulation. Sunda pangolins are believed to engage in polygynous breeding, with males mating with multiple females.

The gestation period lasts around 130 days, and newborn pangolins have soft scales that harden shortly after birth. Weighing between 100 to 500 grams, the young are nursed by the females for three months, who display strong protective behaviour. During their travels and foraging, the baby pangolins often ride on their mother’s tail, and when danger looms, the mother instinctively curls up into a tight ball, providing a secure haven for her young.

Barasingha Cervus duvauceli

Barasingha (Swamp Deer) Cervus duvauceli

Red List Status: Vulnerable

Extant (resident): India; Nepal

Extinct: Bangladesh; Pakistan

Presence Uncertain: Bhutan

Barasinghas Cervus duvauceli also known as Swamp Deers, are instantly recognisable for their enormous handsome antlers. They can have as many as 12 antlers and their namesake Barasinghas means ’12 antlered deer’ in Hindi. They are now one of the most endangered deer species in the world due to habitat fragmentation for palm oil and beef, along with human persecution and hunting. The only remaining population live in protected sanctuaries in India and Nepal. The herd will be led by a single female and then followed by other females in a procession and then the males follow along at the rear of the group. Despite this, females are not dominant over the herd. These resilient, tough and majestic deer species are classified vulnerable on IUCN Red List. If you want to help them, adopt a #Vegan lifestyle and #BoycottPalmOil #Boycott4Wildlife in the supermarket!

Appearance & Behaviour

Barasinghas are a highly social and strongly matriarchal deer species. They typically gather in herds of 10-2o individual deers.

Herds are mostly made up of deer of similar age. Although herds may sometimes be mixed in age and gender. The herd will be led by a single female and then followed by other females in a procession and then the males follow along at the rear of the group. Despite this, females are not dominant over other members of the herd. Males are known to move between herds, whereas females are more loyal to their own herd. Like many other deer species, males are generally referred to as ‘bucks’ and dominant males a ‘stags’.

They are naturally diurnal and active throughout the day. They will typically rest during the heat of midday and spend the dawn and dusk grazing.

Juvenile males will sport smaller antlers that are an extension to their bones and have blood vessels inside of them. This coating of blood vessels or ‘felt’ is lost over time, as the young deers will rub the antlers against trees to toughen the antlers up.

Threats

There are three sub-species of Barasinghas and in total IUCN Red List estimates that there are only 3,500 to 5,100 left alive. They are classified as Vulnerable. Only a small number of Barasinghas live in protected zones, including:

• 350-500 animals in Kaziranga National Park
• 300-350 animals in Kanha National Park

Barasinghas face multiple human-related threats:

• Palm oil deforestation: A significant part of their range is being destroyed for palm oil. They rely on mangroves and swamps and these are drained and destroyed to make way for palm oil.
• Hunting: Hunters often deliberately seek out these deer for their extraordinary antlers.
• Livestock deforestation: Livestock grazing and other agricultural expansion.
• Competition with other animals for food in a shrinking range.
• Diseases: passed on from domestic cattle to the deer.

Habitat

The Barasingha is faces multiple anthropogenic threats which has heavily fragmented their range in north and central India and south west Nepal. They prefer riparian and riverine habitats close to floodplains, wetlands, mangroves and swamps as well as riversides. They are also fund in woodlands and deciduous forests.

Diet

Barasinghas are herbivorous mammals and they provide a vital ecosystem service by ensuring that plants are kept under control with their grazing habits. They generally stick with a diet of foliage, leaves and grass. Some Barasinghas living in wetlands will supplement this diet with algae and aquatic vegetation.

Mating and breeding

Dominant males in herds will mate with a group of females known as a harem. Males in herds will engage in bloody and violent conflicts with each other for mating rights during the rutting season. Male ‘bucks’ call for female ‘does’ using a series of bugling and barking sounds to indicate their readiness to mate. Mating season is between October and February.

Females give birth typically to only one fawn after around eight months of pregnancy. Occasionally twins occur. The fawn is weaned by six to eight months, and after two years, young females reach sexual maturity.

Tana River Mangabey Cercocebus galeritus

Tana River Mangabey Cercocebus galeritus

Red List: Critically Endangered

Location: Kenya

This species is found only along a fragmented 60 km stretch of floodplain forest near the lower Tana River in south-eastern Kenya.

The Tana River Mangabey Cercocebus galeritus is a long-faced and slender old world monkey of #Kenya listed as Critically Endangered due to ongoing habitat destruction, dam construction, logging, and the degradation of floodplain forest ecosystems. Once protected by the Tana River #Primate Reserve, these #monkeys despite being key seed dispersers in their ecosystem are now more vulnerable than ever after the legal de-gazetting of their habitat. With only around 1,000 individuals remaining, this highly social and adaptable primate faces a devastating future unless urgent action is taken. Use your wallet as a weapon to end the destruction of their home. #BoycottPalmOil #Boycott4Wildlife #Vegan #BoycottMeat

Appearance and Behaviour

Tana River Mangabeys are medium-sized monkeys with long, light grey fur and cream-coloured underparts. Their forearms and hands are darker, and their dark grey face is framed by a prominent crest of fur parted down the centre. Their distinctive white eyelids contrast against their darker skin, playing a key role in their complex communication.

These monkeys are diurnal and semi-terrestrial, often seen foraging on the ground, though they sleep high in tree canopies for safety. Social groups are large and structured, with up to 36 individuals living together in mixed-sex groups. Males often perform territorial calls in the early morning, and loud “whoop-gobble” vocalisations can carry over a kilometre, helping to space out neighbouring groups. Their behaviour is deeply affected by food availability: in times of plenty, groups interact peacefully, while in lean months, they grow more territorial.

Diet

Tana River Mangabeys are primarily frugivorous monkeys but display great dietary flexibility. Around 46% of their annual diet consists of seeds, with another 25% made up of fruit. They also consume stems, young leaves, fungi, and insects. During the dry season, when food is scarce, they range further and diversify their diet.

They rely heavily on trees like Ficus sycomorus and Phoenix reclinata for food, both of which fruit at times when other resources are limited. Their powerful jaws and thick molar enamel allow them to crack tough seeds and nuts, and their shortened faces provide increased bite force—an adaptation that suits their opportunistic feeding strategy.

Reproduction and Mating

Tana River Mangabeys live in polygynous groups of monkeys, where one dominant male typically has access to multiple females. Females display conspicuous monthly estrous swellings to signal fertility, and many also exhibit post-conception swellings. These false signals may confuse males and encourage multiple males to invest in infant care, increasing the infant’s survival chances.

Gestation for these monkeys lasts around 180 days, with births most common between August and April. A single infant is born, and the mother is initially left undisturbed by the group. After two months, infants begin to explore and socialise with others. Females likely reach sexual maturity around age three and begin breeding between six and seven, while males mature slightly later.

Geographic Range

Tana River Mangabeys are endemic to Kenya, confined to around 27 forest fragments along a narrow corridor of floodplain forest near the lower Tana River. This range spans from Nkanjonja in the north to Hewani in the south, across an altitudinal range of just 20–40 metres above sea level.

Historically, this species may have had a broader distribution. However, fragmentation due to deforestation, dam construction, and agriculture has severely restricted their movement and isolated populations. Forest corridors are no longer structurally connected, although some functional connectivity remains through limited travel between fragments.

Threats

Tana River Mangabeys live in the flood-plain forest, riverine gallery forest, and the adjacent woodland and bushland of Kenya (Wieczkowski and Butynski 2013). Their abundance is highly correlated with the spatial characteristics of the forests. They are semi-terrestrial monkeys that can travel up to 1 km through non-forested habitat between forest patches (Wieczkowski 2010).

The rapid decline of Tana River Mangabeys has several causes including: Forest clearance for agriculture.

IUCN red list

• Dam construction and water diversion: The building of hydroelectric dams has altered natural flood cycles and disrupted groundwater levels vital to the mangabeys’ habitat. The upcoming High Grand Falls Dam, one of Africa’s largest, threatens to irreparably damage the ecosystem.

• Deforestation and agriculture: Large swathes of gallery forest have been cleared for farming, drastically reducing the species’ habitat. An estimated 50% of the original forest has been lost in the last 20 years.

• Palm exploitation: Phoenix reclinata, a key food tree, is overharvested by local communities for palm wine, thatching, and mats, threatening both food security and habitat structure for the mangabeys.

• Logging and wildfires: Unregulated cutting of canopy and sub-canopy trees for housing and fuelwood, alongside uncontrolled fires, further degrades the forest and isolates populations.

• Human Persecution: As natural resources diminish, some mangabeys are are seen as pests and are persecuted and hunted for raiding crops—a threat expected to grow with increasing human-wildlife conflict.

• Political instability and poor law enforcement: The de-gazetting of the Tana River Primate Reserve in 2007 removed legal protections, exacerbating habitat destruction and reducing conservation oversight.

Take Action!

The Tana River Mangabey is on the brink. If their fragmented forests are lost, so too is this charismatic and intelligent monkey. Support indigenous-led conservation and agroecology efforts in East Africa. Demand the full reinstatement of protected habitat in Kenya. Boycott palm oil and refuse to support the industries driving deforestation and dam construction in critical floodplain ecosystems. #BoycottPalmOil #Boycott4Wildlife #Vegan #BoycottMeat

FAQs

Why are Tana River Mangabeys endangered?

Their biggest threats are habitat loss and fragmentation, largely due to dam construction, logging, agriculture, and palm exploitation. Political instability and poor conservation enforcement have worsened their chances of survival (Butynski & Mwangi, 1994; Wieczkowski & Butynski, 2013).

What are the predators of the Tana River Mangabey?

Natural predators include African rock pythons (Python sebae), crowned eagles (Stephanoaetus coronatus), martial eagles (Polemaetus bellicosus), and Nile crocodiles (Crocodylus niloticus) (Wikipedia, n.d.).

In which country are Tana River Mangabeys found?

They are found exclusively in Kenya.

What do Tana River Mangabeys eat?

Their diet includes fruits, seeds, leaves, insects, stems, and fungi. They rely heavily on species like Ficus sycomorus and Phoenix reclinata (Homewood, 1978; Maingi, 2019).

Do Tana River Mangabeys make good pets?

Tana River Mangabeys are highly social and intelligent primates. Keeping them as pets is cruel and contributes to their extinction. Trapping them destroys wild populations, causes immense suffering, and breaks apart family groups. If you care about these animals, never support the exotic pet trade—advocate for habitat protection instead.

Blue-billed Curassow Crax alberti

Blue-billed Curassow Crax alberti

IUCN Status: Critically Endangered
Location: Colombia

The Blue-billed Curassow is endemic to Colombia, with remaining populations in the tropical forests of the Magdalena Valley, the Sierra Nevada de Santa Marta, and the Serranía de San Lucas. These birds inhabit lowland humid forests and fragmented secondary woodlands, clinging to survival in one of the world’s most deforested biodiversity hotspots.

The endearing Blue-billed Curassow Crax alberti is a unique bird of #Colombia currently classified as Critically Endangered by the IUCN Red List due to rapid habitat loss for multiple different cash crops and intense hunting pressures. Less than 2,500 mature individuals remain, with many subpopulations highly fragmented and isolated. A shy, ground-dwelling bird, Blue-billed Curassows plays an essential role in forest regeneration through #seeddispersal. But #timber, #meat, #goldmining, #coca plantations, and #palmoil agriculture have devoured more than 90% of their original range. Without urgent conservation action, this #bird faces imminent #extinction. Always choose products that are 100% #palmoilfree and go #vegan BoycottPalmOil, always #BoycottGold #Boycott4Wildlife

Appearance and Behaviour

The Blue-billed Curassow is a striking, turkey-sized bird with glossy black plumage in males and a striking pale blue cere at the base of their bill, from which the species takes their name. Females are distinguished by their rufous-brown underparts and barred tails. Both sexes feature a curled crest of black feathers atop their heads, adding to their dramatic appearance (Shanahan, 2017).

They are shy and elusive birds, preferring to forage alone or in pairs along the forest floor. Observations in El Paujil Bird Reserve noted that they forage by scratching leaf litter for fallen fruit, seeds, invertebrates, shoots, and occasionally carrion or even terrestrial crabs (Urueña, 2008a; Melo et al., 2008). Roosting sites are usually located in tree foliage close to feeding areas and reused for several days (Hirschfeld, 2008).

Diet

The Blue-billed Curassow is an omnivore. Its diet is mainly composed of fruit and seeds, but it also consumes invertebrates such as insects, shoots, and occasionally carrion. A recent survey documented seed consumption from at least 15 plant species, as well as one record of terrestrial crab consumption (Urueña, 2008a; Quevedo et al., 2005).

Reproduction and Mating

Breeding occurs primarily in the dry season, with nests observed between December and March. However, studies in the El Paujil Bird Reserve noted a possible second breeding season from July to September (Urueña, 2008b). Clutches typically contain two to three eggs. As with other cracids, both parents may play a role in chick rearing. In the wild, families with chicks are typically observed during March through August (Cuervo & Salaman, 1999).

Geographic Range

Endemic to Colombia, the Blue-billed Curassow once roamed vast tracts of humid lowland forest throughout the northwestern Andes. Now, it persists only in fragmented patches across the Magdalena Valley, the Sierra Nevada de Santa Marta, and the Serranía de San Lucas (Valencia et al., 2023; IUCN, 2023).

Historically, over 90% of its potential range has been cleared or degraded due to deforestation for agriculture, coca plantations, and ranching (Melo et al., 2008). One GIS analysis estimated a 39% loss in potential distribution between 1986 and 2002 alone, with an annual deforestation rate of 2.4% (Melo et al., 2008).

Threats

• Deforestation for agriculture and livestock is the most significant threat to the survival of the Blue-billed Curassow. Almost 90% of their tropical forest habitat in northern Colombia has been cleared or severely degraded due to cattle ranching, rice cultivation, cotton production, palm oil, soy and coca plantations. These activities have fragmented the curassow’s range into isolated patches too small to support viable populations.

• The illegal pet trade and commercial hunting pose a grave threat. Curassows are hunted for meat and occasionally captured for the illegal pet trade. Surveys in Antioquia reported at least 57 individuals killed between 2002 and 2003, mostly during the breeding season, exacerbating their population decline (Melo et al., 2008). Hunting pressure remains high in rural communities surrounding the few remaining forest patches (Cabarcas et al., 2008).

• Political instability and post-conflict development have further imperilled the species. Ironically, decades of civil conflict prevented large-scale deforestation in some remote regions by limiting access to armed groups. However, peace agreements have led to rapid expansion of agriculture, mining, and logging into formerly inaccessible forests, especially in the Sierra Nevada de Santa Marta and Serranía de San Lucas—key strongholds for the species (Shanahan, 2017; Negret et al., 2017).

• Illegal gold mining and drug production have escalated forest destruction and brought with them roads, settlements, and deforestation. The 1996 gold rush in the Serranía de San Lucas resulted in widespread logging and land clearance for coca production. Subsequent government herbicide spraying has further damaged ecosystems essential for the curassow’s survival (Cuervo & Salaman, 1999; Melo et al., 2008).

• Habitat fragmentation has reduced the availability of forest patches larger than 3 km², which are considered the minimum size needed to support a viable population of Crax alberti (Melo et al., 2008). This has severely disrupted dispersal, gene flow, and nesting success.

• Infrastructure projects, such as highways, act as barriers between populations. For example, the Santa Marta-Riohacha Highway isolates birds in Tayrona National Park from those in the nearby Sierra Nevada foothills, reducing connectivity and increasing local extinction risks (Strewe et al., 2010).

• Low reproductive success in captivity threatens the future of ex-situ conservation. As of 2021, there were only 27 Blue-billed Curassows in Colombian zoos, most of them ageing. Only one male was actively breeding, making captive-breeding efforts challenging and precarious (Dueñas Flórez, 2021).

Take Action!

Help protect the Blue-billed Curassow by refusing to support deforestation-linked products and industries. Boycott palm oil, logging, and industrial meat farming, all of which fuel forest loss. Support indigenous-led conservation efforts in Colombia and ecotourism models that empower local communities while preserving habitat. Take action and use your wallet as a weapon! #BoycottPalmOil #Boycott4Wildlife #Vegan #BoycottMeat

FAQs

How many Blue-billed Curassows are left in the wild?

According to the IUCN Red List, there are estimated to be between 150 and 700 individuals remaining in the wild (IUCN, 2023) they are tragically critically endangered. Other sources suggest the total may be as high as 2,500 mature individuals when including fragmented populations across different reserves and national parks.

What is the lifespan of a Blue-billed Curassow?

In the wild, the lifespan is not well documented due to their elusive nature, but it is thought to be around 15–20 years, similar to other large cracids. In captivity, individuals may live longer depending on conditions and veterinary care (Melo et al., 2008).

What are the predators of the Blue-billed Curassow?

Natural predators include large birds of prey and terrestrial mammals such as jaguars and ocelots. However, human hunting remains the dominant threat, particularly targeting adults during breeding season and young birds for food and captivity (Melo et al., 2008; Cabarcas et al., 2008).

Why is the Blue-billed Curassow critically endangered?

This species has suffered catastrophic declines due to habitat destruction, especially from logging, palm oil agriculture, coca plantations, and mining. Additionally, hunting for bushmeat and egg collection has further reduced population numbers. The fragmentation of remaining populations also increases their vulnerability to extinction (Valencia et al., 2023).

White-thighed Colobus Colobus vellerosus

White-thighed Colobus Colobus vellerosus

IUCN Red List Status: Critically Endangered

Location: Ghana, Côte d’Ivoire, Benin, Togo, Nigeria, Burkina Faso

The White-thighed Colobus is found in the forests of West Africa, including lowland rainforest, semi-deciduous forest, gallery forest, and swamp forest. Key strongholds include the Boabeng-Fiema Monkey Sanctuary in Ghana and Kikélé Sacred Forest in Benin.

The White-thighed Colobus (Colobus vellerosus), also known as the Ursine Colobus or Geoffroy’s Black-and-White Colobus, is a striking primate of West Africa and is currently listed as Critically Endangered on the IUCN Red List. Their numbers have plummeted by over 80% in just three generations due to rampant deforestation driven by logging, agriculture, and expanding palm oil plantations. Intense bushmeat hunting and weakening traditional taboos have further accelerated their decline. With fewer than 1,500 individuals thought to remain in the wild, urgent action is needed to save them. Use your wallet as a weapon—boycott products that contain palm oil and support ethical, indigenous-led conservation. BoycottPalmOil #Boycott4Wildlife #Vegan #BoycottMeat

With complex vocalisations and striking halos of white hair, the White-thighed #Colobus 🐵🐒🩷 are arguably rarest #primates in #WestAfrica 🇨🇮 🇬🇭 Help them to survive when you #BoycottPalmOil 🌴🪔🔥🧐⛔️ #Boycott4Wildlife in the supermarket! @palmoildetect https://palmoildetectives.com/2021/02/15/white-thighed-colobus-colobus-vellerosus/

Appearance and Behaviour

The White-thighed Colobus is instantly recognisable by its black fur offset with bright white patches on the thighs and a halo of thick white fur surrounding their bare black face. Their long, fully white tail and slender body give them a unique silhouette among colobines. Infants are born completely white and darken to adult colouration by around three months.

In both Côte d’Ivoire and Ghana, more than half of the closed forest in the forest reserves has been converted to plantation or farmland, or cleared and left bare (Bitty et al. 2015).

IUCN Red List

These monkeys are highly arboreal, agile, and diurnal, moving through the canopy with grace. Their complex vocal repertoire includes deep roaring calls to defend territories and sharp snorts as alarm signals. Group structure typically includes one territorial male with multiple females and their offspring, though multi-male groups are also observed.

Diet

Primarily folivorous, the White-thighed Colobus feeds on young leaves, seeds, fruits, buds, flowers, and bark. Their diet includes more than 30 plant species and varies with seasonal availability. In Kikélé Sacred Forest, they consume large amounts of leaves (over 60%), followed by fruits and other plant parts. They occasionally supplement their diet with termite clay.

Reproduction and Mating

Groups of these colobuses typically include one or more adult males, several females, and their offspring. Group sizes range from 10 to 25 individuals. Breeding occurs year-round, with a likely peak during the dry season. Infants are closely cared for by mothers and other females, fostering a strong social structure. Males often disperse upon reaching sexual maturity.

Geographic Range

The species is found in Ghana, Côte d’Ivoire, Benin, Nigeria, Togo, and possibly the southernmost tip of Burkina Faso. It has been extirpated from many forest reserves in Ghana and Côte d’Ivoire due to extreme hunting and forest clearance. Populations remain in Boabeng-Fiema Monkey Sanctuary (Ghana), Comoé National Park (Côte d’Ivoire), Fazao-Malfakassa National Park (Togo), and Kikélé Sacred Forest (Benin). It is likely extinct in Burkina Faso.

Threats

The White-thighed Colobus is threatened primarily by hunting and secondarily by habitat loss (McGraw 2005). Accelerated hunting pressure is discernible from reported changes in hunters’ behaviour in the species’ range countries. Thirty years ago, hunters in Ghana and Côte d’Ivoire almost always hunted only larger-bodied animals, but now they are mostly hunting smaller-bodied animals because of the depletion of large primates like C. vellerosus (Decher and Kpelle 2005, Gonedelé Bi et al. 2016).

In Comoé National Park in Côte d’Ivoire, several groups remain, but hunting pressure and mining occur although some patrol is in place.

• Deforestation from logging, agriculture, road building, and palm oil plantations has fragmented and destroyed their habitat.
• Palm oil, tobacco and cocoa expansion and industrial production is a major driver of forest clearance across West Africa, particularly in Ghana and Côte d’Ivoire.
• Hunting for bushmeat is rampant, including in protected areas and sacred groves.
• Collapse of traditional taboos that once protected the species has made them vulnerable to killing by local communities.
• Hydropower development, such as the proposed Adjarala dam on the Mono River, threatens forests in Benin and Togo.
• Infrastructure expansion and human settlement continue to encroach on remaining habitats.

Take Action!

Use your wallet as a weapon. Boycott products that contain palm oil—this is one of the leading causes of deforestation that is destroying the forests of the White-thighed Colobus. Avoid meat and dairy, which drive land clearing for grazing and feed crops. Support indigenous-led conservation and community-based sanctuaries like Boabeng-Fiema. Demand governments halt infrastructure projects in critical habitat areas. Take action every time you shop BoycottPalmOil #Boycott4Wildlife be #Vegan and #BoycottMeat

FAQs

How many White-thighed Colobus are left in the wild?

Recent estimates suggest fewer than 1,500 individuals remain across their entire range (IUCN, 2020). In some places, only a few isolated groups survive, such as in Kikélé Sacred Forest (Benin) and Boabeng-Fiema Monkey Sanctuary (Ghana).

What is the average lifespan of the White-thighed Colobus in the wild?

While specific data are scarce, similar species of colobus monkeys live up to 20 years in the wild. In captivity, they may live slightly longer under optimal care.

How are White-thighed Colobuses affected by palm oil?

Palm oil plantations are expanding rapidly in West Africa, replacing biodiverse forests with monocultures. This directly destroys the colobus monkeys’ food sources, sleeping trees, and corridors between forest patches. Products with palm oil continue to drive this destruction.

What are the biggest threats to the White-thighed Colobus?

Besides palm oil, the main threats include logging, conversion of forest to farmland, hunting for bushmeat, infrastructure development (roads and dams), and the erosion of traditional beliefs that once protected them.

Are White-thighed Colobuses sacred to local communities?

Yes, in areas like Boabeng-Fiema and Kikélé, they are considered sacred and are given burial rites. However, these traditions are fading, and poaching still occurs.

Southern White-cheeked Gibbon Nomascus siki

Southern White-cheeked Gibbon Nomascus siki

Red List Status: Critically Endangered

Location: Central Laos (east of Mekong River), Central Vietnam (Ha Tinh, Quang Binh, Quang Tri Provinces)

In the misty canopies of Southeast Asian forests, where ancient trees reach towards clouded peaks and dawn breaks with haunting melodies, Southern White-cheeked Gibbons swing through their rapidly shrinking world.

Southern White-cheeked #Gibbons stand among Southeast Asia’s most melodic #primates, their haunting territorial songs echoing through evergreen forests at dawn. These remarkable apes face an 80% population decline over three generations as #rubber plantations, agricultural expansion, and #hunting devastate their homeland. #Vietnam has lost 15% of its forest cover in just 15 years and could lose another 45% by 2050, while #Laos faces similar destruction.

Help them and #BoycottPalmOil 🌴🚫 @palmoildetect https://palmoildetectives.com/2021/01/29/southern-white-cheeked-gibbon-nomascus-siki/

Appearance and Behaviour

Southern White-cheeked Gibbons display striking sexual dimorphism that transforms with age. Juveniles begin life as light brown infants, turning black after weaning. Adult males remain jet black with distinctive white patches framing their mouths, while females develop rich brown colouring with delicate white facial edging. Their long, powerful arms span up to 1.5 metres, perfectly adapted for their brachiating lifestyle.

These gibbons begin each day with spectacular duet songs that can be heard up to 2 kilometres away. Mated pairs sing together to defend territories and strengthen bonds, their regional accents distinguishing different populations. Southern White-cheeked Gibbons are strictly arboreal, spending their entire lives in the canopy where they move with breathtaking grace and speed.

Diet

Southern White-cheeked Gibbons are primarily frugivorous, spending 33% of their day feeding on diverse forest fruits that ripen throughout the year. They supplement their diet with tender leaves, young shoots, and flowers, occasionally capturing small prey like lizards or Finlayson’s squirrels. These gibbons provide a critical ecosystem service by being seed dispersers, carrying viable seeds in their digestive systems across vast territories before depositing them in new locations through their faeces. Their feeding activities help regenerate forest biodiversity across their 37.9-hectare home ranges.

Reproduction and Mating

Southern White-cheeked Gibbons form monogamous pairs that mate for life, raising their young together in tight family units. Females typically give birth to their first offspring between seven and eight years of age. Because raising young is extremely demanding, both parents share childcare duties, and mothers wait until their current offspring becomes relatively independent before having another infant. Families consist of two parents, a juvenile, and an infant at any given time. Young gibbons leave their parents’ territory once they reach maturity between three and six years of age.

Geographic Range

Southern White-cheeked Gibbons inhabit a restricted range in central Laos east of the Mekong River and central Vietnam’s mountainous provinces. Their historical distribution extended from the Nam Theun and Rao Nay rivers in the north to the Banghiang and Thach Han rivers in the south.

In Vietnam, populations are heavily fragmented and scattered, while in Laos populations of gibbons remain larger. Key populations survive in protected areas including Phong Nha-Ke Bang National Park and Nakai-Nam Theun National Protected Area.

Threats

Timber, rubber and palm oil deforestation

Agricultural expansion converts primary forests into farmland and human settlements, destroying the tall broadleaf evergreen forests Southern White-cheeked Gibbons require for survival. Logging operations target luxury timber species, selectively removing the largest trees that provide crucial fruiting resources and nesting sites.

Rubber cultivation destroys the fruiting trees that sustain gibbon populations while fragmenting territories below viable thresholds for family groups. The conversion process typically involves clear-cutting entire forest sections, eliminating decades of ecological relationships in mere weeks. In Cambodia’s Virachey National Park, large areas have been cleared for rubber production in recent years, particularly along the eastern borders where gibbons once thrived.

Infrastructure development and roads

Infrastructure development opens previously inaccessible areas to human exploitation, bringing roads, settlements, and hunting pressure into formerly secure habitats. The fragmentation creates isolated forest patches too small to support viable gibbon populations, leading to local extinctions across their range. Agricultural conversion eliminates the continuous canopy connections these strictly arboreal primates need for movement and foraging.

Hunting and wildlife trade

Traditional medicine practitioners highly value Southern White-cheeked Gibbons for their body parts. Opportunistic hunting with firearms targets gibbons alongside other wildlife, often killing entire family groups when hunters encounter them.

The illegal pet trade tears infant gibbons from their families, condemning them to lives of isolation and psychological trauma in captivity. Local communities hunt gibbons for bushmeat, viewing them as readily available protein sources. Gun ownership and hunting access have increased significantly with infrastructure development, bringing previously secure populations within reach of hunters. The small group sizes and territorial nature of gibbon families make them particularly vulnerable to hunting pressure.

Take Action!

Use your wallet as a weapon and #BoycottPalmOil #Boycott4Wildlife every time you shop. Adopt a vegan lifestyle protecting both wild and farmed animals from agricultural expansion. Support indigenous-led protection recognising traditional forest guardianship. Refuse products containing rubber from deforested areas and demand supply chain transparency. #BoycottPalmOil #Boycott4Wildlife #Vegan

FAQs

What sounds do Southern White-cheeked Gibbons make?

Southern White-cheeked Gibbons are renowned for their spectacular dawn songs that can be heard up to 2 kilometres away through dense forest. Mated pairs perform elaborate duets combining whoops, hoots, and melodic phrases that last 15-30 minutes each morning. These territorial songs serve to defend their home ranges and strengthen pair bonds between mates. Each population has developed regional accents, with slight variations in song structure distinguishing different gibbon communities across their range. Males typically begin the duet with deep hooting calls, while females add higher-pitched, more complex phrases that create hauntingly beautiful harmonies echoing through the forest canopy.

How high can Southern White-cheeked Gibbons swing?

Southern White-cheeked Gibbons are masterful brachiators, swinging through forest canopies 15-50 metres above the ground using their extremely long arms and powerful shoulder joints. They travel at speeds reaching 55 kilometres per hour through the canopy. Their incredible agility allows them to navigate dense forest canopies with extraordinary precision.

How long do Southern White-cheeked Gibbons live?

Southern White-cheeked Gibbons can live 35-40 years. Young gibbons remain with their parents for 3-6 years, learning essential survival skills including territorial singing, foraging techniques, and canopy navigation.

Are Southern White-cheeked Gibbons dangerous to humans?

These gentle apes are primarily frugivorous and spend their time high in forest canopies, far from human activity. Their territorial behaviour is directed only towards other gibbon groups, not humans, and consists of vocal displays rather than physical aggression.

Do Southern White-cheeked Gibbons make good pets?

It is deeply cruel to keep these wild apes as pets. Southern White-cheeked Gibbons suffer extreme psychological trauma, loneliness, and early death in captivity. The illegal pet trade rips infant gibbons from their families, causing severe trauma while removing potential breeding individuals from critically endangered populations.

Captive Southern White-cheeked Gibbons often develop depression and aggression as they attempt to cope with social isolation and environmental deprivation. Legal ownership is prohibited under CITES Appendix I and national laws in both Vietnam and Laos.

Why do Southern White-cheeked Gibbons sing?

Southern White-cheeked Gibbons sing elaborate duets to defend their territories, strengthen pair bonds, and communicate with neighbouring families across the forest landscape. These dawn songs serve as acoustic boundaries, informing other gibbon groups about occupied territories and preventing potentially dangerous physical confrontations. Mated pairs coordinate their duets to demonstrate their strong partnership and reproductive fitness to potential rivals. The songs also help family members locate each other in dense forest canopies and may serve to teach young gibbons proper vocal techniques essential for establishing their own territories. Regional variations in song structure function like dialects, allowing gibbons to identify members of their local population versus strangers from distant areas.

Golden-mantled Tree Kangaroo Dendrolagus pulcherrimus

Golden-mantled Tree Kangaroo Dendrolagus pulcherrimus

Red List Status: Critically Endangered

Location: Papua New Guinea (Torricelli Range), West Papua (Foja Mountains)

In the misty cloud forests of New Guinea’s mountains, where ancient trees emerge from perpetual fog and birdsong echoes through emerald canopies, Golden-mantled Tree Kangaroos move with quiet grace through their vanishing world.

Golden-mantled Tree Kangaroos are one of the world’s rarest marsupials. Rarely glimpsed in the wild, their distinctive chestnut coats are adorned with golden stripes. These remarkable climbing kangaroos have suffered a catastrophic 90% population decline over three generations, leaving fewer than 500 individuals clinging on for survival in two remote mountain ranges. Palm oil expansion strips away their ancient forest homes while hunting pressure decimates remaining populations. The Tenkile Conservation Alliance protects the Torricelli population through community-based conservation, offering hope for recovery. #BoycottPalmOil #Boycott4Wildlife

Golden-mantled Tree #Kangaroos 🦘🤎 are critically endangered #marsupials of #PapuaNewGuinea 🇵🇬 They’re on the edge of #extinction from #palmoil #deforestation and #hunting. Resist for them and #Boycottpalmoil 🌴☠️🤮🙊⛔️ #Boycott4Wildlife @palmoildetect https://palmoildetectives.com/2021/01/26/golden-mantled-tree-kangaroo-dendrolagus-pulcherrimus/

Appearance and behaviour

The lowland areas of their distribution are earmarked for deforestation and oil palm expansion.

IUCN Red List

These resilient Tree Kangaroos display the physiological adaptations of arboreal marsupials with chestnut-brown coats, pale bellies, and distinctive double golden stripes running down their backs. Their yellowish necks, cheeks, and feet create a striking contrast against their darker fur, while their powerful tails marked with pale rings provide essential balance during canopy travel. These compact marsupials measure 40-77 centimetres in body length with tails reaching 40-87 centimetres.

Golden-mantled Tree Kangaroos possess powerful forelimbs and curved claws perfectly adapted for gripping bark and branches. Their shorter hind legs allow independent movement essential for navigating complex three-dimensional forest environments. Unlike ground kangaroos, these arboreal specialists can move both forwards and backwards along branches, using their long tails as fifth limbs for stability and balance.

Diet

Golden-mantled Tree Kangaroos are primarily folivorous, feeding on leaves from dozens of plant species found throughout their montane forest habitat. They supplement their diet with seasonal fruits, herbs, and sedges, spending considerable time foraging both in trees and on the forest floor. These selective feeders prefer young leaves and shoots from specific plant species, making them vulnerable when preferred food sources disappear.

Their feeding behaviour includes both arboreal and terrestrial foraging, with Golden-mantled Tree Kangaroos descending to ground level to access fallen fruits and herbs. This dietary flexibility has allowed them to persist in their restricted mountain habitats, though their dependence on specific plant species makes them particularly vulnerable to habitat conversion and fragmentation.

Reproduction and mating

Golden-mantled Tree Kangaroos reach sexual maturity at approximately two years of age with no defined breeding season. Females have an oestrous cycle estimated at 54 days with a gestation period of about 45 days. Once born, the tiny joey remains in the mother’s pouch for 10 months before emerging to spend another 2-3 months at foot, learning essential climbing and foraging skills.

These marsupials live relatively long lives, with captive individuals surviving over 14 years, suggesting wild Golden-mantled Tree Kangaroos could live 8-10 years under optimal conditions. Their extended dependency period reflects the complex skills required for arboreal survival, with mothers teaching joeys essential climbing techniques and food recognition during their extended care period.

Geographic Range

Golden-mantled Tree Kangaroos now survive in only two isolated mountain ranges across New Guinea. The Torricelli Range population in Papua New Guinea extends from Weight to Kuliek, while a smaller population persists in West Papua’s Foja Mountains. Fossil records indicate they once ranged across the Vogelkop Peninsula and other areas, but have been extirpated from 99% of their historical range.

Unconfirmed sightings from Papua New Guinea’s Prince Alexander Range suggest possible remnant populations, though these require verification. Their extremely restricted range of just 300 square kilometres makes Golden-mantled Tree Kangaroos particularly vulnerable to local extinctions from habitat loss, hunting, or natural disasters.

Threats

Industrial palm oil deforestation

Palm oil companies systematically bulldoze and burn Golden-mantled Tree Kangaroo habitat across West Papua, replacing mid-montane rainforests with lifeless monocultures. Korean company Korindo has destroyed 11,700 hectares of pristine rainforest in recent years, eliminating the complex canopy structure these arboreal marsupials require for survival. The company burns forests illegally, knowing this practice destroys critical habitat for tree kangaroos, birds of paradise, and cassowaries. Palm oil expansion has eliminated lowland portions of their range entirely, forcing Golden-mantled Tree Kangaroos into higher elevation refuges. Plantation development fragments the continuous forest cover essential for these territorial animals, creating isolated patches too small to support viable populations.

Hunting for bushmeat

Local communities hunt Golden-mantled Tree Kangaroos for subsistence protein, targeting them with guns during opportunistic forest expeditions. Hunting pressure intensifies near human settlements where access improves through road development and infrastructure expansion. The species’ small group sizes and territorial nature make them particularly vulnerable to hunting pressure, with entire local populations eliminated through intensive harvesting.

Infrastructure and road projects

Road construction opens previously inaccessible mountain areas to human exploitation, bringing hunting pressure and habitat disturbance into formerly secure territories. Small-scale agriculture eliminates forest understory vegetation while creating edge effects that degrade remaining habitat quality. The conversion of traditional forest management systems to intensive agriculture removes the ecological balance that historically supported both human communities and wildlife populations.

FAQs

How do Golden-mantled Tree Kangaroos climb trees?

Golden-mantled Tree Kangaroos have powerful forelimbs with curved claws that grip bark securely, while their shorter hind legs allow independent movement essential for navigating branches. They possess strong grips on their paws and foot soles providing non-slip traction when climbing. Their long tails act as fifth limbs, pressing against tree trunks for balance and stability during movement.

What do Golden-mantled Tree Kangaroos eat?

Golden-mantled Tree Kangaroos are primarily herbivorous, feeding on leaves from 91 known plant species, seasonal fruits, herbs, and sedges found in their montane forest habitat. They spend considerable time foraging both in trees and on the forest floor, preferring young leaves and shoots from specific plant species. Some sources suggest they occasionally consume young birds and bird eggs, though their diet consists predominantly of plant matter. Their selective feeding habits make them vulnerable when preferred food sources disappear due to habitat conversion or climate change.

How long do Golden-mantled Tree Kangaroos live?

In the wild, they typically live approximately 8-10 years, though current threats including hunting and habitat destruction may be reducing average lifespans. Captive individuals have survived over 14 years, suggesting they have potential for longer lifespans when protected from human pressures. Their generation length is approximately 10 years, indicating they reach reproductive maturity relatively late compared to smaller marsupials.

How big are Golden-mantled Tree Kangaroos?

Golden-mantled Tree Kangaroos measure 40-77 centimetres in body length with tails reaching 40-87 centimetres, making them substantially smaller than ground kangaroos. They weigh approximately 15.5 kilograms, a relatively light build essential for their arboreal lifestyle where they must be supported by tree branches. Both males and females are similar in size, showing less sexual dimorphism than many other kangaroo species.

Why are Golden-mantled Tree Kangaroos endangered?

Tragically, these tree kangaroos have experienced a catastrophic 90% population decline over three generations due to palm oil deforestation and hunting pressure. Palm oil companies have destroyed 99% of their historical habitat, replacing mid-montane rainforests with monoculture plantations offering no food or shelter. Hunting for bushmeat provides essential protein for local communities but removes breeding individuals from critically small populations. Their extremely restricted range of just 300 square kilometres makes them vulnerable to local extinctions, while habitat fragmentation prevents genetic exchange between isolated populations.

Can Golden-mantled Tree Kangaroos jump?

Golden-mantled Tree Kangaroos are capable jumpers, able to leap distances of up to 9 metres between trees and drop up to 18 metres to the forest floor without injury. They can climb heights equivalent to a 10-storey building, using their powerful hind legs and long tails for balance during aerial manoeuvres. Their jumping ability allows them to navigate between the treetops without descending to the dangerous ground level where predators pose greater threats. Their remarkable leaping capacity is essential for accessing food sources and escaping danger in their three-dimensional forest environment.

By boycotting palm oil and embracing a vegan lifestyle, you’re not just helping them, but also our planet. The palm oil industry and meat industry directly and indirectly causes tropical deforestation, destroying the homes of countless animals, including the Red-shanked Douc Langur, #Boycottpalmoil, be #vegan and #Boycott4Wildlife

Appearance and Behaviour

Red-Shanked Douc Langurs are breathtakingly colourful. Their expressive golden faces, surrounded by delicate white whiskers, radiate intelligence and calmness. Their crimson-red lower legs and silvery thighs create a striking contrast against their sleek black torsos and long, white-tipped tails.

These diurnal primates live in the treetops, leaping gracefully from branch to branch with their powerful limbs and prehensile tails. They are highly social, often living in groups of up to 50 individuals, led by a dominant male. Communication is subtle and involves gentle vocalisations, body language, and eye contact.

Geographic Range

Red-Shanked Douc Langurs are native to Vietnam, Laos, and Cambodia, inhabiting dense tropical forests. They prefer the canopy of subtropical and tropical evergreen forests, where they remain hidden from predators. However, deforestation and habitat fragmentation have significantly reduced their range, confining them to isolated patches of forest.

Diet

Primarily folivorous, Red-Shanked Douc Langurs consume a wide variety of young leaves, which make up the bulk of their diet. They also feed on fruits, flowers, seeds, and buds, depending on seasonal availability. Their multi-chambered stomachs are specially adapted to ferment fibrous plant material, allowing them to extract essential nutrients from their diet.

Reproduction and Mating

Red-Shanked Douc Langurs have a gestation period of approximately 165–190 days, typically resulting in a single infant. Newborns are born with pale fur, which darkens as they grow. There is no fixed breeding season, and births occur year-round. Both parents are actively involved in raising their offspring, strengthening the social bonds within their group.

Threats

The Red-Shanked Douc Langur is listed as Critically Endangered on the IUCN Red List. Conservation efforts include habitat protection, anti-poaching patrols, and the rescue and rehabilitation of individuals caught in the wildlife trade. Organisations such as the Endangered Primate Rescue Center in Vietnam are at the forefront of these efforts, working tirelessly to protect these magnificent animals and their habitats.

IUCN Status: Critically Endangered

Habitat loss has also been a major threat in Vietnam with extensive logging for coffee, rubber, and cashew plantations (Nadler et al. 2004), and in Lao PDR where logging is underway at an increasing rate.

IUCN Red List

Deforestation for palm oil, timber and other agriculture: Deforestation for agriculture, logging, and infrastructure development has destroyed vast areas of their habitat. Habitat loss has also been a major threat in Vietnam with extensive logging for coffee, rubber, and cashew plantations (Nadler et al. 2004), and in Lao PDR where logging is underway at an increasing rate for mining, agriculture, forestry and hydropower projects, mostly by large Chinese and Vietnamese companies (Smirnov 2015). Habitat loss and fragmentation have led to an increase in access to remote forests for illegal hunting of the red-shanked douc, contributing to the alarming declines of the global population.

Illegal Wildlife Trade: They are heavily targeted for traditional medicine, as trophies, and for the pet trade.

Climate Change: Changes in rainfall and temperature patterns impact their food sources and habitats, further threatening their survival.

Take Action!

Protect the Red-Shanked Douc Langur by boycotting products linked to deforestation, such as palm oil. Support conservation organisations working to preserve their habitats and enforce anti-poaching laws. Share their story and advocate for their survival with #BoycottPalmOil and #Boycott4Wildlife.

Conservation efforts for this species of langur are underway

Thomas’s Langur Presbytis thomasi

Thomas’s Langur Presbytis thomasi

IUCN Status: Vulnerable (VU)

Location: Indonesia – Sumatra (Aceh Province)

Thomas’s Langur, also known as the North Sumatran Leaf #Monkey is famous for their bold facial stripes giving them a handsome profile. These monkeys are endemic to the lush forests of northern Sumatra, Indonesia. Listed as Vulnerable by the Red List, this striking species is facing serious population declines due to habitat loss, primarily driven by illegal logging and oil palm deforestation. Though not as globally known as some of its neighbours, such as the Sumatran Orangutan, Thomas’s Langur plays an equally vital role in forest regeneration and seed dispersal. You can help protect them by using your consumer power: always choose palm oil-free products.#BoycottPalmOil #Boycott4Wildlife #Vegan

Appearance and Behaviour

Thomas’s Langur is a small-bodied, highly distinctive primate. Their expressive amber eyes are framed by a whimsical ‘mohawk’ of fur – white at the front and dark grey along the midline – with flaring white cheek tufts giving them a perpetual look of surprise. Their back and limbs are grey, while the underparts are pure white, creating a dramatic contrast. Infants are born almost entirely white.

They live in social groups of 10–20 individuals and are arboreal, moving gracefully through the canopy. Though they are agile and peaceful, these monkeys are alert and cautious, especially in areas with higher predator or infanticide risk. They’ve been observed adjusting their vigilance levels depending on their location within the forest and the presence of neighbouring groups.

Diet

Thomas’s Langur is primarily folivorous, meaning their diet mainly consists of leaves. However, they also consume unripe fruit, flowers, toadstools, snails, and even rubber tree seeds when available. They have highly adapted digestive systems with gut microbes capable of breaking down cellulose, allowing them to extract nutrients from fibrous plant material. They tend to avoid ripe fruit, which could kill these microbes, and instead prefer high-pH, less acidic produce.

Reproduction and Mating

These langurs reach reproductive maturity around 5.4 years of age. The average interbirth interval is about 22 months, though this can vary depending on whether the previous infant survives. Females give birth to a single offspring at a time and care for them extensively. Infanticide by incoming males is a documented threat in overlapping territories, which may influence both vigilance and social dynamics within groups.

In the wild, Thomas’s Langurs live up to 20 years, with longevity extending to 29 years in captivity due to the absence of predators and reduced stress.

Geographic Range

Thomas’s Langur is restricted to northern Sumatra in Indonesia, primarily within Aceh Province. They are found north of the Alas (Simpangkiri) and Wampu Rivers, though newer records suggest they also exist just south of the Alas. Key populations reside in the Leuser Ecosystem, particularly around the Ketambe Research Station and Bukit Lawang in Gunung Leuser National Park. The species’ range is geographically fragmented by rivers and human activity.

Threats

The species is considered Vulnerable due to past and continued population declines, estimated at more that 30% over the past 40 years (three generations) due to loss of habitat, especially to logging and oil palm plantations. Due to continuing threats, it is suspected to decline at the same rate over the next one generation.

IUCN Red List

• Palm oil and timber deforestation

Thomas’s langur faces severe habitat loss due to widespread deforestation in northern Sumatra. Logging operations, both legal and illegal, have cleared vast tracts of primary forest, fragmenting the langurs’ habitat and forcing them into smaller, isolated patches. The conversion of forests into oil palm plantations is accelerating this destruction, leading to population declines estimated at more than 30% over the past 40 years. This fragmentation not only reduces available food sources but also isolates groups, limiting genetic diversity and increasing the risk of local extinctions.

• Hunting and human persecution

Though protected by the local Batak traditional and religious taboos, there is some ‘marginal’ hunting pressure in the other parts of their distribution. The species is sometimes killed for bushmeat or captured for traditional medicine practices. In areas where these taboos are not observed, or where poverty drives people to seek alternative food sources, hunting pressure remains a real threat. Even low levels of hunting can have significant impacts on slow-reproducing primates like Thomas’s langur.

• Illegal Pet Trade

Infant langurs are often captured and sold in wildlife markets, especially in areas close to tourism hotspots like Bukit Lawang. To obtain a baby, adult females are usually killed, which has devastating consequences for troop dynamics and survival. Captive langurs often suffer from malnutrition, stress, and poor care, and rarely survive long in the pet trade. This exploitation is driving the species further toward extinction and contributes to the destruction of wild populations.

• Human-Wildlife Conflict

As forests are cleared, Thomas’s langurs increasingly move into croplands and plantations in search of food. This brings them into direct conflict with farmers, who may perceive them as pests and shoot them to protect crops. These retaliatory killings are not only cruel but contribute to the already rapid decline in population numbers. Furthermore, such conflicts reduce public tolerance for the species and hinder conservation efforts unless addressed through community engagement and education.

FAQs

How many Thomas’s Langurs are left in the wild?

Exact population estimates for the Thomas’s Langur are unknown, but data suggests that their numbers have declined by more than 30% in the past 40 years (three generations). This is largely due to habitat destruction and fragmentation (Wich et al., 2007).

How long do Thomas’s Langurs live?

In the wild, they typically live around 20 years. In captivity, individuals have been known to live up to 29 years (Wich et al., 2007).

Why are Thomas’s Langurs endangered?

The main threat is deforestation from logging and conversion of land into palm oil plantations. This leads to loss of their primary rainforest habitat and forces them into closer contact with humans, where they may be shot or captured for trade (IUCN, 2021).

Do Thomas’s Langurs make good pets?

Absolutely not. Keeping Thomas’s Langurs as pets is not only unethical but illegal. The illegal pet trade contributes directly to their decline, as infants are taken from their mothers, often involving violence. Supporting this trade fuels cruelty and threatens their survival. Advocate against the exotic pet trade instead.
