Carnaby's black cockatoo
Carnaby's black cockatoo (''Calyptorhynchus latirostris''), also known as Carnaby's cockatoo or short-billed black cockatoo,〔Christidis, Les and Walter E. Boles (2008) ''Systematics and Taxonomy of Australian Birds'' ISBN 978-0-643-06511-6〕 is a large black cockatoo endemic to south-western Australia. It was described in 1948 by naturalist Ivan Carnaby. It is threatened by habitat destruction.
==Description==
Carnaby's black cockatoo is about 55 cm (21.5 in) long. It is mostly dark grey, with narrow light grey scalloping produced by narrow pale grey margins at the tips of dark feathers. It has a crest of short feathers on its head, with whitish patches of feathers that cover the ears. Its lateral tail feathers are white with black tips, and the central tail feathers all black. The irises are dark brown and the legs brown-grey. Its beak is shorter and broader than that of the closely related and similar long-billed black cockatoo.〔
Adult males have a dark grey beak and pink eye-rings. Adult females have a bone coloured beak, grey eye-rings and ear patches that are paler than those of the males. Juveniles have a bone coloured beak, grey eye-rings, and less white in the tail feathers.〔Forshaw (2006). plate 1.〕
