Carnaby's black cockatoo (Calyptorhynchus latirostris), also known as the short-billed black cockatoo, is a large black cockatoo endemic to southwest Australia. It was described in 1948 by naturalist Ivan Carnaby. Measuring 53–58 cm (21–23 in) in length, it has a short crest on the top of its head. Its plumage is mostly greyish black, and it has prominent white cheek patches and a white tail band. The body feathers are edged with white giving a scalloped appearance. 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.
This cockatoo usually lays a clutch of one to two eggs. It generally takes 28 to 29 days for the female to incubate the eggs, and the young fledge ten to eleven weeks after hatching. The young will stay with the family until the next breeding season, and sometimes even longer. The family leaves the nesting site after the young fledge until the following year. Carnaby's black cockatoo forms flocks when not breeding, with birds in drier habitats usually being more migratory than those in wetter ones. It flies with deep and slow wingbeats, generally high above trees. Seeds of plants of the families Proteaceae and, to a lesser extent, Myrtaceae form a large part of its diet.
Carnaby's black cockatoo nests in hollows situated high in trees with fairly large diameters, generally Eucalyptus. With much of its habitat lost to land clearing and development and threatened by further habitat destruction, Carnaby's black cockatoo is listed as an endangered species by the Federal and Western Australian governments. It is also classified as endangered by the International Union for Conservation of Nature (IUCN). Like most parrots, it is protected by CITES, an international agreement that makes trade, export, and import of listed wild-caught species illegal.
