Sunda Flying Lemur Galeopterus variegatus
Sunda Flying Lemur Galeopterus variegatus
Locations: Thailand, Cambodia, Vietnam, Laos, Myanmar, Peninsular Malaysia, Singapore, Brunei, Indonesia (Java, Sumatra, Kalimantan, Bali), and Borneo
The Sunda flying lemur, also known as the Malayan flying lemur or Malayan #colugo, silently glides through the tropical forests of Southeast Asia, relying on ancient forests to survive. Despite their name, they are not true lemurs, nor do they fly—they are gliders, and among the most skilful in the world. This species is experiencing population declines in several parts of their range. They are threatened by #deforestation from #timber, #palmoil plantations, and #hunting by local communities. Forest loss, particularly in #Java, #Vietnam, and #Thailand, is fragmenting their populations and endangering their survival. Use your wallet as a weapon every time you shop and protect these sensitive creatures #BoycottPalmOil #Boycott4Wildlife

Share to BlueSky Share to TwitterAppearance & Behaviour
Sunda flying lemurs are hauntingly beautiful gliding mammals, with their large, forward-facing eyes adapted for night vision and a delicate, kite-shaped membrane of skin called a patagium stretching from their neck to their fingertips, tail, and toes. This structure allows them to glide over 100 metres through the forest canopy, losing as little as 10 metres in elevation. On the ground, they are nearly helpless, but in the trees, they move with astonishing agility. These quiet, nocturnal mammals spend their days curled up in tree hollows or nestled in the dense fronds of coconut trees, becoming active at dusk when they begin foraging.
Threats
Palm oil deforestation
The widespread clearing of tropical rainforest to establish palm oil plantations is one of the greatest threats to the Sunda flying lemur. These gliders rely heavily on continuous tree canopy for movement, foraging, and breeding. When forests are fragmented or entirely removed for palm oil, flying lemurs become stranded, exposed to predators, and unable to access food or shelter. This process has caused severe habitat degradation across Peninsular Malaysia, Sumatra, and Borneo.
Human persecution and hunting
In Java and some other regions, Sunda flying lemurs are hunted by local communities, including the Baduy Tribe, who increase hunting activity every four years as part of cultural practices. Though the species yields little meat, they are still killed for consumption or perceived nuisance. Hunting disrupts already fragile populations, particularly in areas where habitat loss has already reduced numbers and isolated groups.
Logging and forest fragmentation for timber
Commercial and illegal logging contribute to the rapid degradation of forests across Southeast Asia. Even selective logging can cause fragmentation, which limits the flying lemur’s ability to glide and forces them to descend to the ground—where they are highly vulnerable to predators and human threats. Logging roads also increase human access to remote forests, further accelerating hunting and forest conversion.
Competition with invasive species
In degraded habitats and plantations, Sunda flying lemurs face increased competition for food and nesting sites from invasive and generalist species such as the Plantain Squirrel (Callosciurus notatus). These squirrels are more adaptable and can dominate food sources, leaving less for the more specialised colugo. Competition like this puts additional stress on the already fragile populations of flying lemurs, especially in fragmented or edge habitats.
Urban expansion and infrastructure development
Rapid urbanisation across Southeast Asia has resulted in the encroachment of cities and towns into previously forested areas. Roads, buildings, hydroelectric dams and agricultural expansion sever vital canopy corridors and isolate populations, making gliding impossible in many urban landscapes. As a result, Sunda flying lemurs are forced to navigate unsuitable environments, increasing their risk of vehicle collisions, electrocution from power lines, and conflict with humans.
Weak protections and lack of enforcement
Although the Sunda flying lemur is legally protected in several countries, enforcement is often weak or inconsistent. In areas like Sarawak and Java, data on current populations is outdated or incomplete, making it difficult to assess trends or plan effective conservation strategies. Without strong protections and ongoing monitoring, habitat loss and hunting will continue to drive the species toward future vulnerability or extinction.
Geographic Range
Sunda flying lemurs are found across Southeast Asia, including Thailand, Cambodia, Vietnam, Laos, southern Myanmar, Peninsular Malaysia, Singapore, Brunei, and Indonesia (Java, Bali, Sumatra, Kalimantan, and Borneo). They are patchily distributed, with population declines noted in Java and possibly Sarawak. They occur in both primary and secondary forests, and are sometimes seen in plantations and gardens—but dense forest canopy is critical for their survival. Populations in disturbed habitats are less viable due to limited gliding space and reduced food availability.
Diet
The Sunda flying lemur feeds primarily on young leaves, buds, shoots, flowers, and fruits of a wide variety of forest trees. In Bako National Park, Sarawak, they have been observed feeding on over 12 tree species, with Buchanania arborescens making up over 50% of their diet. They also consume tree sap and have even been seen licking bark for water and minerals. Interestingly, they have been recorded feeding on ants (Paratrechina longicornis) in rare cases, highlighting their adaptability in changing environments.
Mating and Reproduction
After a gestation period of about 60 days, females give birth to a single young, which clings to the mother’s belly and is cradled within the folds of the patagium. The mother’s gliding membrane acts like a living pouch, offering warmth and protection as she climbs and glides through the treetops. Not much else is known about their mating systems or breeding intervals, but juveniles stay with their mothers until they are old enough to glide on their own.
FAQs
How many Sunda flying lemurs are left in the wild?
Exact population numbers are unknown, but the species is believed to be in slow decline. Localised extinctions are suspected in parts of Java and mainland Southeast Asia due to hunting and habitat fragmentation. While still widespread, their dependence on intact forests makes them vulnerable to ongoing deforestation (Boeadi & Steinmetz, 2008).
How long do Sunda flying lemurs live?
In the wild, their lifespan is estimated to be around 10–15 years, though this can vary depending on threats and environmental conditions. Data from wild populations are limited due to their elusive, nocturnal habits (Wikipedia, n.d.).
Why are they threatened by palm oil?
Palm oil plantations destroy the lowland tropical forests that flying lemurs depend on. Unlike other adaptable mammals, colugos require dense canopy cover for safe gliding, resting, and breeding. When forests are cleared, these gliders lose their ability to navigate safely, exposing them to predators and starvation. The conversion of rainforest into monoculture plantations has led to significant declines in habitat quality across their range (Lim et al., 2013; Nasir & Abdullah, 2009).
Do Sunda flying lemurs make good pets?
Absolutely not. Sunda flying lemurs are wild animals with specialised needs. They are not domesticated, and keeping them as pets leads to extreme stress, injury, or death. Capturing these animals for trade disrupts family groups and contributes to their extinction. If you care about flying lemurs, advocate against the exotic pet trade and never support it.
What conservation efforts are underway?
National laws protect the Sunda flying lemur in many range countries, and studies have been conducted in places like Bako National Park and Singapore. However, much stronger protection is needed, particularly in habitat protection and indigenous-led conservation. Conservationists recommend protecting forest patches, especially those with >95% canopy cover, to ensure their survival (Lim et al., 2013).
Take Action!
Protect the Sunda flying lemur by choosing only products that are 100% palm oil-free. Avoiding palm oil directly combats deforestation and preserves vital canopy corridors these animals depend on. Support indigenous-led agroecology and forest protection movements. Never support the exotic pet trade or keep wild animals in captivity. Every purchase you make has the power to either destroy or safeguard their rainforest homes. #BoycottPalmOil #Boycott4Wildlife

Bornean White-bearded Gibbon Hylobates albibarbis
Bornean White-bearded Gibbon Hylobates albibarbis
Endangered
Indonesia (Kalimantan)
The Bornean White-bearded Gibbon belongs to the genus Hylobates. The word Hylobates means ‘Forest Walker’ in Greek. The gibbons in this genus are known for the white circle of fur around their faces. They are known to communicate in species-specific song when defining territory or attracting mates. They sing in regional accents to each other, have long swinging arms, inquisitive natures and superior acrobatic skills, they spend most of their lives high up in the tree-tops.
The Bornean White-bearded Gibbon is an intelligent and dynamic gibbon of the genus Hylobates (meaning forest walker in Greek). Endangered @IUCNredlist from complex threats incl. #palmoil #deforestation in #Kalimantan #Boycott4Wildlife
The Bornean White-bearded Gibbon is considered Endangered under Criterion A4cd, based on an overall suspected population reduction of 50% or more over the previous two generations (1990-2019), which is also expected to continue impacting the current generation (2020-2035).
IUCN Red List
The Bornean White-bearded Gibbon is chiefly arboreal and diurnal. This species is socially monogamous and highly territorial (Mitani 1987); estimates of territory size are 47 ha at Sabangau (Cheyne 2010) and 30-43 ha at Gunung Palung (Mitani 1990; Marshall 2004). These gibbons prefer to eat ripe, sugar-rich fruits (Cheyne 2008, Cheyne et al. 2016, Dillis et al. 2014, McConkey 2000, Singh et al. 2018) although unripe fruits, immature leaves, insects, and flowers are consumed during periods of low fruit abundance (Coiner-Collier et al. 2016, McConkey 1999). The species inhabits a range of primary, secondary and selectively logged tropical evergreen forest types (Cheyne 2010, Cheney et al. 2016, Harrison et al. 2010, Marshall et al. 2009). Peat swamp forest is a particularly important forest type for the Bornean White-bearded Gibbon (Cheyney 2008, 2010; Cheyney et al. 2008). Population densities are correlated with forest structure (Hamard et al. 2010, Cheyne et al. 2016, Marshall et al. 2014), altitude (Marshall 2009), and the abundance of important fallback foods (Marshall and Leighton 2006).
The Bornean White-bearded Gibbon is considered Endangered under Criterion A4cd, based on an overall suspected population reduction of 50% or more over the previous two generations (1990-2019), which is also expected to continue impacting the current generation (2020-2035). The reduction is driven by a corresponding loss of suitable habitat (that has averaged 1% annually in Borneo over the past 30 years) and is expected to continue at that rate (or higher) for the next 10 to 20 years, as well as by significant losses due to hunting and live capture for the pet trade.

This species is socially monogamous and highly territorial (Mitani 1987); estimates of territory size are 47 ha at Sabangau (Cheyne 2010) and 30-43 ha at Gunung Palung (Mitani 1990; Marshall 2004). These gibbons prefer to eat ripe, sugar-rich fruits (Cheyne 2008, Cheyne et al. 2016, Dillis et al. 2014, McConkey 2000, Singh et al. 2018) although unripe fruits, immature leaves, insects, and flowers are consumed during periods of low fruit abundance (Coiner-Collier et al. 2016, McConkey 1999). The species inhabits a range of primary, secondary and selectively logged tropical evergreen forest types (Cheyne 2010, Cheney et al. 2016, Harrison et al. 2010, Marshall et al. 2009). Peat swamp forest is a particularly important forest type for the Bornean White-bearded Gibbon (Cheyney 2008, 2010; Cheyney et al. 2008). Population densities are correlated with forest structure (Hamard et al. 2010, Cheyne et al. 2016, Marshall et al. 2014), altitude (Marshall 2009), and the abundance of important fallback foods (Marshall and Leighton 2006).
The Bornean White-bearded Gibbon is considered Endangered under Criterion A4cd, based on an overall suspected population reduction of 50% or more over the previous two generations (1990-2019), which is also expected to continue impacting the current generation (2020-2035). The reduction is driven by a corresponding loss of suitable habitat (that has averaged 1% annually in Borneo over the past 30 years) and is expected to continue at that rate (or higher) for the next 10 to 20 years, as well as by significant losses due to hunting and live capture for the pet trade.

Bornean White-bearded Gibbon Hylobates albibarbis
Bornean White-bearded Gibbon Hylobates albibarbis
Endangered
Indonesia (Kalimantan)
The Bornean White-bearded Gibbon belongs to the genus Hylobates. The word Hylobates means ‘Forest Walker’ in Greek. The gibbons in this genus are known for the white circle of fur around their faces. They are known to communicate in species-specific song when defining territory or attracting mates. They sing in regional accents to each other, have long swinging arms, inquisitive natures and superior acrobatic skills, they spend most of their lives high up in the tree-tops.

Storm’s Stork Ciconia stormi
IUCN Red List Status: Endangered
Location: Malaysia, Indonesia, Thailand, Brunei
Found in lowland riverine and peat swamp forests of #Borneo, #Sumatra, Peninsular #Malaysia, and southern #Thailand. Core strongholds include the floodplains of Sabah and peat swamps of #Kalimantan.
Storm’s Stork Ciconia stormi is the rarest and most elusive #stork in Asia, and one of the world’s most threatened. Currently listed as #Endangered by the IUCN Red List, with fewer than 500 individuals remaining in the wild, their continued survival hangs by a thread in #Malaysia #Indonesia #Thailand and #Brunei. These elegant, black-and-white #birds once ranged widely across the Sundaic region. Today, their numbers are spiralling due to large-scale #deforestation for #palmoil plantations, logging, and infrastructure projects like dams and roads that slice through their forest home.
Peat swamp #forests—critical for nesting and foraging—are rapidly disappearing. But you can help turn the tide. Use your wallet as a weapon to protect these remarkable birds. Choose products that are 100% #palmoilfree and support indigenous-led conservation. #BoycottPalmOil #Boycott4Wildlife #Vegan

Appearance and Behaviour
With their sleek black plumage, brilliant white undertail, and arresting red facial skin encircled by a yellow eye ring, Storm’s Storks are unmistakeable once seen—if seen at all. Adults stand at 75–91 cm tall, their red legs often stained white from perching high in the canopy. They are silent outside the breeding season but may utter soft whistling or a frog-like call at the nest.
Unlike many storks, they are shy and solitary, rarely seen in groups. They glide high above the forest on thermals, and are often seen alone or in pairs near quiet, muddy riverbanks. Nesting high in tall trees, often overhanging rivers, they raise just two chicks a year with intense parental care and secrecy.
Diet
Storm’s Stork feeds primarily on small fish, frogs, worms, aquatic insect larvae and sometimes crustaceans and grasshoppers. They stalk quietly along shaded forest streams and oxbow lakes, moving slowly and deliberately. Parents regurgitate these prey items into the nest for their young, with foraging usually taking place 2–3 km away from their nesting site.
Reproduction and Mating
Monogamous pairs construct large twig nests high in the canopy, often reusing the same nest over several years. Nesting takes place in primary forest close to rivers, with clutches of two eggs and chicks fledging after approximately 90 days. Breeding displays include aerial flips and ground-based mutual bowing. Both parents take turns incubating the eggs and feeding the chicks, although the female tends to remain longer at the nest.
Geographic Range
Storm’s Stork occurs at extremely low densities across Borneo (Malaysia, Brunei, Indonesia), Sumatra, Peninsular Malaysia, and southern Thailand. Borneo is its core range, especially in Kalimantan and Sabah, where it persists in lowland peat swamps and riverine forests. Once present across the Greater Sundas, it is now extinct or nearly so in Thailand and Myanmar. In Sumatra, populations remain on the Kampar Peninsula, Way Kambas, and Siberut. In Peninsular Malaysia, only small relict populations exist, mostly within Taman Negara.
Threats
Ciconia stormi is native to the swamp and plains-level forests of the Greater Sundas, where it occurs at a very low density and nowhere is numerous. Over the past three generations (31 years: 1992–2023), it is suspected of having declined rapidly (40–60%) in response to industrial removal of its habitat for agro-industry plantations, particularly oil-palm and rubber. Its global population size is uncertain, but probably numbers 300–1,750 mature individuals; with ongoing habitat loss compounded by forest fires which may increase with frequency in response to climate change, this species is considered to be a high risk of extinction in the near-term. Accordingly, it is listed as Endangered.
IUCN Red list
• Widespread deforestation for palm oil and rubber plantations has destroyed much of the lowland forest habitat that Storm’s Stork depends on.
• Peat swamp forests, their stronghold in Borneo, are being drained, logged and set alight, especially during El Niño years.
• Logging roads fragment the forest and degrade rivers through erosion and sedimentation, reducing aquatic prey.
• Forest fires intensify due to human activities, especially in drained peatlands, further eliminating habitat and nesting sites.
• Hydropower projects, like the Chiew Larn Dam in Thailand, have flooded large tracts of prime habitat.
• Hunting still occurs, though not the primary driver of decline. These sensitive birds abandon nests if disturbed.
• Captive trade was a minor historic threat; however, tamed birds in zoos are unlikely to be rewilded successfully.
• Climate change and habitat fragmentation create uncertain future conditions, especially for isolated populations on Sumatra and the Malay Peninsula.
Take Action!
Storm’s Stork is a symbol of everything we stand to lose through the reckless destruction of rainforests. You have power to stop this.
Use your wallet as a weapon and boycott palm oil. Refuse to buy from companies that drive deforestation. Support indigenous-led agroecology. Speak out against the destruction of Southeast Asia’s peat swamp forests. Take action every time you shop and #BoycottPalmOil #Boycott4Wildlife, be #Vegan!
FAQs
How many Storm’s Storks are left in the wild?
Estimates suggest only 260–500 individuals remain globally. Around 240–1,600 mature individual birds may persist in Borneo, especially in Kalimantan. Sumatra’s population may be as low as 50–100 mature birds, while Peninsular Malaysia and Thailand hold fewer than 10 pairs each (BirdLife International, 2021; Martin et al., 2024).
How long do Storm’s Storks live?
Although exact data is scarce, storks in the genus Ciconia are long-lived, with some individuals living more than 20 years in the wild. Their slow reproductive rate and long lifespan make population recovery difficult after sharp declines (Danielsen et al., 1997; BirdLife International, 2021).
Why is palm oil so destructive for Storm’s Stork?
Palm oil expansion targets the very peat swamp and lowland forests Storm’s Stork calls home. These habitats are easy to access and commercially valuable, making them first to be logged, drained, and cleared. The result is mass habitat loss, water pollution, fire risk, and collapsing food chains that leave the storks with nowhere to nest or feed (Miettinen et al., 2011; Harrison et al., 2016).
Are Storm’s Storks affected by hunting or the pet trade?
They are hunted opportunistically by forest dwellers and poachers, especially as access increases through roads. However, hunting is not the main cause of their decline. The pet trade spiked in the late 1980s, but today, habitat loss remains the overwhelming threat (BirdLife International, 2021; Martin et al., 2024).

Sabah Grizzled Langur Presbytis sabana
Sabah Grizzled Langur Presbytis sabana
Red List Status: Endangered
Location: Malaysia (Sabah), Indonesia (North Kalimantan)
This elusive primate lives in lowland, riparian, montane, and evergreen forests of northern Borneo, including protected areas such as the Danum Valley, Tabin Reserve, and the Kinabatangan region.
The Sabah Grizzled Langur Presbytis sabana, also known as the Saban Grizzled #Langur or Crested Grizzled Langur, is a strikingly beautiful leaf #monkey found only in #Borneo. Their #Endangered status is a direct result of extensive habitat destruction caused by deforestation, out-of-control palm oil expansion, and #hunting—particularly for bezoar stones used in traditional medicine. With fragmented populations and little known about their behaviour or numbers, urgent action is needed to prevent their extinction. Use your wallet as a weapon. Avoid #palmoil when you shop and demand an end to wildlife trafficking and forest destruction. #BoycottPalmOil #Boycott4Wildlife #Vegan

Share to BlueSky Share to TwitterAppearance and Behaviour
The Sabah Grizzled Langur is a captivating primate with a thick coat of grey, grizzled fur and a pale belly, sharply contrasted by black hands and feet. A pointed crown of fur rises from their head, giving them a distinct, almost regal look. Their spade-shaped, pale-pinkish faces are framed by dark rings around wide, expressive eyes—an appearance that makes them instantly memorable to anyone lucky enough to see one.
These langurs are diurnal and arboreal, spending most of their lives high in the forest canopy. At night, they retreat to the upper branches of emergent trees to sleep, likely as a defence against predators. They are nimble and versatile movers, walking on all fours, leaping, climbing, and even hanging suspended beneath branches. Their daily lives involve foraging, grooming, resting, and socialising in cohesive groups that typically consist of one dominant male and several adult females with their young.
Diet
Sabah Grizzled Langurs are primarily folivores, feeding on a wide range of leaves, young shoots, and unripe seeds. They also eat fruit, flowers, buds, insects, bird eggs, and mineral-rich mud to supplement their diet. Their complex, multi-chambered stomachs ferment leafy material efficiently, allowing them to extract maximum nutrition from tough plant matter.
The diet of the Sabah Grizzled Langur shifts based on the level of forest disturbance. In undisturbed forests, leaves dominate their intake, but in logged areas, they consume more fruit and seeds. This adaptability may be crucial to their survival in fragmented landscapes.
Reproduction and Mating
This species follows a polygynous mating system, with a single adult male having exclusive breeding access to the females in the group. Breeding appears to occur year-round, but births peak between July and October. After a gestation of five to six months, the female gives birth to a single infant.
Infants are born with paler fur that darkens over time. They are weaned at around 11 months and become subadults between 21 and 36 months. Both males and females leave their natal groups upon reaching sexual maturity at about three years of age, either joining new groups or forming their own.
Geographic Range
Sabah Grizzled Langurs are endemic to the island of Borneo and are found only in Sabah (Malaysia) and northern parts of Indonesian Kalimantan. They inhabit evergreen, lowland, montane, and riverine forests, as well as selectively logged areas and tree plantations. Though once considered a subspecies of Presbytis hosei, they are now recognised as a distinct species. Populations are scattered and fragmented, with some surviving in protected areas like Danum Valley and the Maliau Basin, but others are highly vulnerable to extinction.
Threats
• Palm oil deforestation, monoculture expansion and habitat fragmentation
Large-scale clearing of Borneo’s forests for palm oil plantations has severely reduced the habitat of Presbytis sabana. This deforestation not only destroys the canopy cover they rely on for movement and shelter but also creates isolated forest patches that hinder gene flow and increase vulnerability to inbreeding and local extinction. Even selectively logged areas can remove critical roosting trees and food sources, leading to population collapse over time.
• Hunting for their meat and bezoar stones
Local hunting poses a grave threat to this species. Bezoar stones—calcified objects sometimes found in the gastrointestinal tracts of langurs—are falsely believed to have medicinal properties and fetch high prices in illegal markets. As a result, these langurs are hunted both for meat and for supposed curative use, putting intense pressure on already dwindling populations.
• Lack of enforcement in protected areas
While some populations live in conservation zones, many of these are inadequately protected. Illegal logging, poaching, and encroachment continue within the boundaries of national parks and reserves. Without sufficient monitoring, resources, and community involvement, these areas offer little real safety for the langurs.
• Low reproductive rate and slow population recovery
Like many primates, Sabah Grizzled Langurs have slow reproductive cycles, giving birth to a single infant every one to two years. This low birth rate means that even small increases in mortality can cause long-term population declines. Combined with hunting and habitat loss, this makes recovery especially difficult without urgent conservation action.
Take Action!
The fate of the Sabah Grizzled Langur is partially tied to our consumer choices. Avoid products that contain palm oil, especially those contributing to Bornean deforestation. Never support the exotic animal trade or products made from endangered species. Support indigenous-led conservation efforts and protect Southeast Asia’s remaining rainforests. #BoycottPalmOil #Boycott4Wildlife #Vegan #BoycottMeat
FAQs
How many Sabah Grizzled Langurs are left?
Exact population numbers are unknown due to a lack of comprehensive surveys, but the IUCN lists them as Endangered and rapidly declining. Fragmentation of their range and localised hunting make many populations highly vulnerable, and some may already be functionally extinct.
What is the lifespan of Presbytis sabana?
While the exact lifespan of Presbytis sabana is not documented, related langurs typically live around 20–25 years in the wild. Infant mortality may be high in disturbed habitats, especially where hunting pressure is intense.
Why are bezoar stones a threat?
Bezoar stones are hard masses found in the intestines of some langurs, falsely believed to have healing powers in traditional medicine. This belief drives illegal hunting, even though scientific evidence shows these stones have no proven medical value. Killing langurs for this purpose is both cruel and contributes directly to their extinction.
How are Sabah Grizzled Langurs affected by palm oil?
Palm oil plantations are a major cause of deforestation in Borneo. These plantations clear vast areas of native forest, severing the canopy corridors that langurs use to travel. Even plantations that claim to be ‘eco-friendly’ contribute to ecosystem collapse by fragmenting habitat and displacing wildlife.
Do Sabah Grizzled Langurs make good pets?
No. These langurs are not suited to captivity and have not been documented in zoos or pet markets. Their specialised diet and social needs cannot be met outside the wild. Keeping langurs as pets is illegal, unethical, and further threatens their survival.

Sabah Grizzled Langur Presbytis sabana
Sabah Grizzled Langur Presbytis sabana
Red List Status: Endangered
Location: Malaysia (Sabah), Indonesia (North Kalimantan)
This elusive primate lives in lowland, riparian, montane, and evergreen forests of northern Borneo, including protected areas such as the Danum Valley, Tabin Reserve, and the Kinabatangan region.
The Sabah Grizzled Langur Presbytis sabana, also known as the Saban Grizzled #Langur or Crested Grizzled Langur, is a strikingly beautiful leaf #monkey found only in #Borneo. Their #Endangered status is a direct result of extensive habitat destruction caused by deforestation, out-of-control palm oil expansion, and #hunting—particularly for bezoar stones used in traditional medicine. With fragmented populations and little known about their behaviour or numbers, urgent action is needed to prevent their extinction. Use your wallet as a weapon. Avoid #palmoil when you shop and demand an end to wildlife trafficking and forest destruction. #BoycottPalmOil #Boycott4Wildlife #Vegan

Share to BlueSky Share to TwitterAppearance and Behaviour
The Sabah Grizzled Langur is a captivating primate with a thick coat of grey, grizzled fur and a pale belly, sharply contrasted by black hands and feet. A pointed crown of fur rises from their head, giving them a distinct, almost regal look. Their spade-shaped, pale-pinkish faces are framed by dark rings around wide, expressive eyes—an appearance that makes them instantly memorable to anyone lucky enough to see one.
These langurs are diurnal and arboreal, spending most of their lives high in the forest canopy. At night, they retreat to the upper branches of emergent trees to sleep, likely as a defence against predators. They are nimble and versatile movers, walking on all fours, leaping, climbing, and even hanging suspended beneath branches. Their daily lives involve foraging, grooming, resting, and socialising in cohesive groups that typically consist of one dominant male and several adult females with their young.
Diet
Sabah Grizzled Langurs are primarily folivores, feeding on a wide range of leaves, young shoots, and unripe seeds. They also eat fruit, flowers, buds, insects, bird eggs, and mineral-rich mud to supplement their diet. Their complex, multi-chambered stomachs ferment leafy material efficiently, allowing them to extract maximum nutrition from tough plant matter.
The diet of the Sabah Grizzled Langur shifts based on the level of forest disturbance. In undisturbed forests, leaves dominate their intake, but in logged areas, they consume more fruit and seeds. This adaptability may be crucial to their survival in fragmented landscapes.
Reproduction and Mating
This species follows a polygynous mating system, with a single adult male having exclusive breeding access to the females in the group. Breeding appears to occur year-round, but births peak between July and October. After a gestation of five to six months, the female gives birth to a single infant.
Infants are born with paler fur that darkens over time. They are weaned at around 11 months and become subadults between 21 and 36 months. Both males and females leave their natal groups upon reaching sexual maturity at about three years of age, either joining new groups or forming their own.
Geographic Range
Sabah Grizzled Langurs are endemic to the island of Borneo and are found only in Sabah (Malaysia) and northern parts of Indonesian Kalimantan. They inhabit evergreen, lowland, montane, and riverine forests, as well as selectively logged areas and tree plantations. Though once considered a subspecies of Presbytis hosei, they are now recognised as a distinct species. Populations are scattered and fragmented, with some surviving in protected areas like Danum Valley and the Maliau Basin, but others are highly vulnerable to extinction.
Threats
• Palm oil deforestation, monoculture expansion and habitat fragmentation
Large-scale clearing of Borneo’s forests for palm oil plantations has severely reduced the habitat of Presbytis sabana. This deforestation not only destroys the canopy cover they rely on for movement and shelter but also creates isolated forest patches that hinder gene flow and increase vulnerability to inbreeding and local extinction. Even selectively logged areas can remove critical roosting trees and food sources, leading to population collapse over time.
• Hunting for their meat and bezoar stones
Local hunting poses a grave threat to this species. Bezoar stones—calcified objects sometimes found in the gastrointestinal tracts of langurs—are falsely believed to have medicinal properties and fetch high prices in illegal markets. As a result, these langurs are hunted both for meat and for supposed curative use, putting intense pressure on already dwindling populations.
• Lack of enforcement in protected areas
While some populations live in conservation zones, many of these are inadequately protected. Illegal logging, poaching, and encroachment continue within the boundaries of national parks and reserves. Without sufficient monitoring, resources, and community involvement, these areas offer little real safety for the langurs.
• Low reproductive rate and slow population recovery
Like many primates, Sabah Grizzled Langurs have slow reproductive cycles, giving birth to a single infant every one to two years. This low birth rate means that even small increases in mortality can cause long-term population declines. Combined with hunting and habitat loss, this makes recovery especially difficult without urgent conservation action.
Take Action!
The fate of the Sabah Grizzled Langur is partially tied to our consumer choices. Avoid products that contain palm oil, especially those contributing to Bornean deforestation. Never support the exotic animal trade or products made from endangered species. Support indigenous-led conservation efforts and protect Southeast Asia’s remaining rainforests. #BoycottPalmOil #Boycott4Wildlife #Vegan #BoycottMeat
FAQs
How many Sabah Grizzled Langurs are left?
Exact population numbers are unknown due to a lack of comprehensive surveys, but the IUCN lists them as Endangered and rapidly declining. Fragmentation of their range and localised hunting make many populations highly vulnerable, and some may already be functionally extinct.
What is the lifespan of Presbytis sabana?
While the exact lifespan of Presbytis sabana is not documented, related langurs typically live around 20–25 years in the wild. Infant mortality may be high in disturbed habitats, especially where hunting pressure is intense.
Why are bezoar stones a threat?
Bezoar stones are hard masses found in the intestines of some langurs, falsely believed to have healing powers in traditional medicine. This belief drives illegal hunting, even though scientific evidence shows these stones have no proven medical value. Killing langurs for this purpose is both cruel and contributes directly to their extinction.
How are Sabah Grizzled Langurs affected by palm oil?
Palm oil plantations are a major cause of deforestation in Borneo. These plantations clear vast areas of native forest, severing the canopy corridors that langurs use to travel. Even plantations that claim to be ‘eco-friendly’ contribute to ecosystem collapse by fragmenting habitat and displacing wildlife.
Do Sabah Grizzled Langurs make good pets?
No. These langurs are not suited to captivity and have not been documented in zoos or pet markets. Their specialised diet and social needs cannot be met outside the wild. Keeping langurs as pets is illegal, unethical, and further threatens their survival.

Bornean Banded Langur Presbytis chrysomelas
Bornean Banded Langur Presbytis chrysomelas
Critically Endangered
Brunei; Indonesia (Kalimantan); Malaysia (Sarawak)
The Bornean banded langur, known for its striking black and white coat, is one of Southeast Asia’s most elusive and endangered primates. These langurs inhabit the fragmented lowland forests and peat swamps of Borneo, relying on dense foliage for their survival.
The population of Bornean banded langurs is rapidly declining due to habitat destruction for palm oil plantations, illegal logging, and hunting. As their habitat continues to shrink, these shy and rarely seen primates face an uncertain future. Use your wallet as a weapon—boycott palm oil and join the fight for their survival. #BoycottPalmOil #Boycott4Wildlife

Share to BlueSky Share to TwitterThis species of Langur is listed as Critically Endangered as it is only known from five sites, where populations have been reduced by approximately 80% over the past 30 years (three generations) and the trend is suspected to continue into the future due to habitat loss from expanding oil palm cultivation.
IUCN Red List
In addition, the area of occupancy has been reduced dramatically. This species was once considered common. They are now considered one of the rarest primates in the world. They live in less than 5% of their historic range. Additional conservation measures are urgent as this species could go extinct if current trends continue.
Appearance and Behaviour
Bornean banded langurs are medium-sized monkeys, reaching about 50–60 cm in body length with a long, slender tail often exceeding their body length. They are distinguished by their unique black and white banded coat, which provides excellent camouflage among tree branches. Their expressive faces, encircled by pale fur, give them an inquisitive and alert appearance.
Primarily arboreal and diurnal, they spend most of their time in the upper forest canopy, where they live in small groups of 3–10 individuals. Group dynamics often include a dominant male, several females, and their offspring. Bornean banded langurs are highly social and communicate using a range of vocalisations, including soft grunts and alarm calls when sensing danger.
Geographic Range
These langurs are endemic to Borneo and are found in Malaysia’s Sabah and Sarawak regions as well as Indonesia’s Kalimantan. Their preferred habitats include lowland dipterocarp forests, peat swamps, and mangroves. However, habitat destruction has fragmented their range, leaving populations isolated in areas such as Danau Sentarum National Park and Tanjung Datu National Park (IUCN, 2020).
Diet
Bornean banded langurs are folivorous, primarily feeding on young leaves, flowers, seeds, and unripe fruits. Their specialised stomachs are adapted to digest fibrous plant material efficiently, enabling them to extract maximum nutrients from their diet. This diet also plays a vital role in seed dispersal, contributing to forest regeneration and biodiversity (NePrimate Conservancy, 2024).
Reproduction and Mating
These langurs exhibit a slow reproductive cycle. Females typically give birth to a single infant every 1–2 years after a gestation period of about 6 months. Infants are born with bright orange coats, which gradually transition to the adult black and white coloration as they mature.
Mothers provide extensive care, with other group members occasionally assisting in grooming or protecting the young. This communal care highlights their highly social nature. However, the slow reproductive rate makes it difficult for the species to recover from population declines.
Threats
The Bornean banded langur is listed as Critically Endangered by the IUCN, with populations continuing to decline. Conservation efforts focus on habitat restoration and protection in key national parks such as Danau Sentarum and Tanjung Datu. Organisations are also working to combat illegal logging and raise awareness about the impact of palm oil.
IUCN Status: Critically Endangered
- Palm oil and timber deforestation: Deforestation for palm oil plantations and logging has decimated much of their forest habitat. Between 2000 and 2018, more than 30% of suitable habitat was lost across Borneo.
- Hunting and poaching: Although not commonly targeted, these langurs are occasionally hunted for bushmeat or captured for the exotic pet trade.
- Habitat fragmentation: Habitat fragmentation isolates populations, reducing genetic diversity and increasing the risk of local extinction.
- Climate Change: Rising temperatures and changes in rainfall patterns threaten the health of their forest ecosystems.
Take Action!
Protect the Bornean banded langur by boycotting palm oil and supporting conservation programs focused on preserving Borneo’s forests. Raise awareness about their plight and advocate for stronger legal protections. Together, we can secure a future for these remarkable primates. #BoycottPalmOil #Boycott4Wildlife
