Its tail feathers are solid black with broad white bands with black tips. It is mostly black, with narrow white scalloping on the margins of dark feathers. On its head it has longer feathers that form a short crest that can be raised and lowered and a prominent patch of cream-white feathers on its cheek. The Carnaby’s black cockatoo or short-billed black cockatoo grows to 53–58 cm in length with approximately 100cm wingspan, and weighs between 520–790 grams. It is estimated that the Carnaby’s population have decreased in number by 50%.ĭescription of the Carnaby’s cockatoo Female Carnaby’s on the left and male Carnaby’s on the right © Due to the rarity of these cockatoos, poaching is also a common issue.Although tissue testing for pesticide residues has been consistently negative, some birds have demonstrated depression of acetylcholinesterase in plasma and brain, indicative of exposure to anti-cholinesterase compounds.
CHiPS might be a result of exposure to organophosphate (OP) pesticides which are widely used on crops in northern breeding areas. Scientists are presently researching why Carnaby’s are affected by this syndrome. With intensive supportive care, many cases will improve over 7-10 days to full use of their legs. The syndrome only affects Carnaby’s Cockatoo, which migrates to metropolitan Perth in the summer from breeding grounds in the north. As a result, their condition rapidly deteriore due to their inability to feed. Poisoning: A syndrome colloquially known as “CHiPS”: Cockatoo Hindlimb Paralysis Syndrome affects Carnaby’s Black Cockatoos which are then unable to stand or walk.Some people and farmers unfortunately consider these cockatoos as pest. Despite the fact that it is illegal to shoot these cockatoos, it is still a major threat to the survival of the species. Unfortunately, this is a major cause of death and injury on the Swan Coastal Plain as Perth suburbs continue to expand and new roads are created. These cockatoos can be seen feeding in native bushland along the road, however due to their size, they need time to take off. Death / injury from motor vehicle strikes.Habitant fragmentation is also a major threat to the species as the Carnaby’s black cockatoos therefore need to travel longer distances to feed and drink, especially during breeding season.This decline has been mainly caused by a loss of habitat and breeding sites from ongoing clearing of native vegetation since the 1950s.Īpproximately 87% of Carnaby’s cockatoo habitat in the Wheatbelt has been cleared. Once seen in flocks of thousands that blackened the sky like rain clouds, this magnificent bird is nowadays listed as endangered by WA and Australian governments and by the International Union for the Conservation of Nature. It is estimated that there is now between 20,000 to 40,000 left in the wild.Ĭlick here to read the latest Great Cocky Count report. As a large proportion of the remaining population is now beyond the breeding age, there may be very few younger birds to take their place. They are only found in Western Australia (endemic) north of Kalbarri, east to Merredin, south to Hopetown and east to Cape Arid near Esperance. These striking birds were named in honour of naturalist Ivan Carnaby. Their scientific name is Calyptorhynchus latirostris. Carnaby’s live for 25 – 50 years. The Carnaby’s black cockatoo or also known as short-billed black cockatoo or even white tailed black cockatoo, is found only in southwest of western Australia. The Carnaby’s Black Cockatoo: An iconic bird in Western Australia The Carnaby’s black cockatoo is now listed as endangered. The only problem is, 90% of what is now the Wheatbelt used to be bushland, and this cockatoo is running out of places to breed and feed. They migrate back and forth from the Swan Coastal Plain where they feed during the summer, to the Wheatbelt where they breed in tree hollows during the winter. With its famous white tail and ‘wee-loo’ call, most people in Perth recognise this iconic species.
