Is it a horn? Is it a feather? This bird, might be a bit confused.

The Laughing Kookaburra is the largest of all kingfishers. The iconic laughing call is actually a challenge to neighbours. Kookaburras operate in collectives and form territories. At dawn and dusk they line up on the boundaries and call loudly at rivals. Over time the boundaries change as group strength fluctuates.

Mammals have two way breathing (in and out). When a bird breathes in, it draws air into sacs below the lungs. Gas exchange occurs in the lungs, and sacs above the lungs take the CO2 rich waste. As they breathe out, they bring the fresh air from the lower sacs into the lungs and the spent air moves into the upper sacs. So they still breathe in and out through the nares and mouth, but are always getting fresh air

Co-operative breeding is a rare mating system where not all offspring leave the parents and instead remain to help raise siblings. It is significantly more common in Australia and Africa, possibly due to the influence of nest parasites like cuckoos. Helping raise your siblings means you are still passing on your genes as siblings share 25% DNA, but raising a cuckoo passes on none.

The birds with the weirdest crests are Cock-of-the-rock, two species of Cotinga from South America. They get their name from nesting in rock faces. The males are the only birds with a crest that extends all the way to the bill. Females are of course much more sensible.

While the Moa of Aotearoa New Zealand were the largest living bird between the extinction of the Elephant bird in Madagascar and their own extinction around 1400CE, they were not without a predator. Haast's Eagle would swoop down from trees to kill moa. They went extinct after Moa disappeared, but given they were large enough to take human prey it is possible they were not tolerated by the newly arrived Maori when they established their lands 700 years ago.

Ostriches are the heaviest birds in the world, and also the largest. Standing at up to 2.8m (9feet) tall, they can weigh more than 150kg (350 pounds). However this is merely the runt cousin of some extinct species. The largest of Aotearoa New Zealand's Moa could have reached 3.6m, and the Elephant bird of Madagascar could have weighed up to 850kg.

Bird facts with Graham
The smallest bird in the world is the Bee hummingbird from Cuba, measuring only 6cm from bill to tail and weighing an astonishing 2-2.5 grams.
Other things weighing 2 grams:
An American dime coin
UK 6 pence
A cashew
Australian 5c piece
A ziplock sandwich bag
Coke bottle cap
Half a teaspoon of sugar

Bird facts with Graham
Migratory birds can find their way across hemispheres without any maps. A chemical called magnetite in their brain helps them detect north and south, and the number of hours of daylight tells them when it's time to move on. Cryptochrome in their eyes let's birds have a visual detection of the Earth's magnetic field. This explains how seabirds and shorebirds are able to cross oceans without any landmarks.

Bird facts with Graham
While our eyes can detect red, blue, and green light, bird eyes can also detect ultraviolet light. That means the colour patterns on bird feathers can look different to them than they do to us.
Many flowering plants display UV colours, so lots of animals evolved the ability to see them. This led to UV colours in bird plumages and eggs. See alt text for details of the images.

A woodpecker can hit a tree at roughly 1000 Gs of deceleration, and that should be catastrophic. So, what happens? #evolution #woodpecker #birdfacts #animalscience #evolutionarybiology

Bird facts with Graham
When Europeans arrived in Aotearoa New Zealand, they brought invasive pests like rats with them. Since there were no predators of small birds, many were flightless and nested on the ground. The rats ate their eggs and most species went extinct. The one group which managed to survive were the kiwis, since their eggs are so big the rats couldn't roll them away. Kiwis are Ratites like ostriches and emus, with similar sized eggs.

Bird facts with Graham
The New Zealand Black robin population fell to only 5 individuals in the 1990s. They were brought back from the brink by cross fostering - taking eggs from the last remaining breeding pair and placing them in the nest of a pair of Chatham Island tits. In an extraordinary turnaround, they species is now up to 350 individuals.

Bird facts with Graham
Birds of paradise skins were traded as currency between the indigenous peoples of eastern Indonesia and Papua New Guinea. They removed the legs while preparing the skins. Having never seen live birds, the first Europeans to see these legless skins thought the birds never came to land and spent their entire lives in the air

Cockatoos nest in tree hollows. The small cockatoos like Galahs are sometimes chased out of their own nests by Sulphur-crested cockatoos, which are larger and can fight them off to claim the nest for themselves. Sometimes a Galah will have already laid eggs in the nest, and the chicks hatch to be raised by the SCC with their own chicks. These Galahs think they are SCCs and spend their whole lives in SCC flocks.

Something cool I learned from the ironically named @lowqualityfacts: Cormorants float in seawater, but sink in freshwater, due to the differing density. That's why people put out these floating cormorant platforms in the river!

I know there are some folks on here who enjoy both #DnD archetypes and #BirdFacts, so let me interest you in this: the #bard of birds!
It’s the latest episode of May Contain #Science and I’ll be honest, I’ve never found cockatoos so dreamy 🥰
