![]() ![]() The three species of the genus Zanda have been variously considered as two, then as a single species for many years. Males and females of Calyptorhynchus sensu stricto differ markedly in appearance, whereas those of Zanda have similar plumage. The two genera differ in tail colour, head pattern, juvenile food begging calls and the degree of sexual dimorphism. The three species of Zanda were formerly included in Calyptorhynchus (and still are by some authorities), but are now widely placed in a genus of their own due to a deep genetic divergence between the two groups. lathami), form the genus Calyptorhynchus. The two red-tailed species, red-tailed black cockatoo ( C. funerea) of eastern Australia, form the genus Zanda. Īmong the black cockatoos, the two Western Australian white-tailed species (Carnaby's and Baudin's black cockatoos), together with the yellow-tailed black cockatoo ( Z. The holotype specimen is from Hopetoun, Western Australia. The epithet latirostris is from the Latin latus "wide" and rostrum "bill". He classified the large-billed form as a subspecies of the white-tailed black cockatoo in 1948, giving it the name Calyptorhynchus baudinii latirostris. These birds lived in mallee and sandplains, using their large bills to crack open woody seed pods the typical form had a long narrow bill it used to extract eucalypt seeds from marri seed pods. ![]() In a 1933 report on the birds of Lake Grace, Western Australian naturalist Ivan Carnaby wrote of a distinctive population of white-tailed black cockatoos that he named mallee black cockatoos. ![]() Like most parrots, it is protected by CITES, an international agreement that makes trade, export, and import of listed wild-caught species illegal.Ĭarnaby's black cockatoo and Baudin's black cockatoo were once known collectively as the white-tailed black cockatoo ( Calyptorhynchus baudinii) until formally classified as separate species. It is also classified as endangered by the International Union for Conservation of Nature (IUCN). 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. Seeds of plants of the families Proteaceae and, to a lesser extent, Myrtaceae form a large part of its diet.Ĭarnaby's black cockatoo nests in hollows situated high in trees with fairly large diameters, generally Eucalyptus. It flies with deep and slow wingbeats, generally high above trees. Carnaby's black cockatoo forms flocks when not breeding, with birds in drier habitats usually being more migratory than those in wetter ones. The family leaves the nesting site after the young fledge until the following year. The young will stay with the family until the next breeding season, and sometimes even longer. It generally takes 28 to 29 days for the female to incubate the eggs, and the young fledge ten to eleven weeks after hatching. This cockatoo usually lays a clutch of one to two eggs. Adult females have a bone-coloured beak, grey eye-rings and ear patches that are paler than those of the males. Adult males have a dark grey beak and pink eye-rings. The body feathers are edged with white giving a scalloped appearance. Its plumage is mostly greyish black, and it has prominent white cheek patches and a white tail band. Measuring 53–58 cm (21–23 in) in length, it has a short crest on the top of its head. It was described in 1948 by naturalist Ivan Carnaby.
