Baudin's black cockatoo
Baudin's black cockatoo (''Calyptorhynchus baudinii''), also known as Baudin's cockatoo or long-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 found in Australia. The binomial commemorates the French explorer Nicolas Baudin.
==Description==
Baudin's black cockatoo is about 56 cm (22 in) long. It is mostly dark-grey with narrow vague light-grey scalloping, which is produced by narrow pale-grey margins at the tip of dark-grey feathers. It has a crest of short feathers on its head, and it has whitish patches of feathers that cover its ears. Its lateral tail feathers are white with black tips, and the central tail feathers are all black. The irises are dark brown and the legs are brown-grey. Its beak is longer and narrower than that of the closely related and similar Carnaby's black cockatoo.〔
The adult male has a dark grey beak and pink eye-rings. The adult female has a bone coloured beak, grey eye-rings, and its ear patches are paler than that of the male. Juveniles have a bone coloured beak, grey eye-rings, and have less white in the tail feathers.〔Forshaw (2006). plate 1.〕
One individual had reached an age of 47 years by 1996.
