Cacatua sp - MHNT. Cacatua is a genus of cockatoos found from the Philippines, Indonesia, Papua New Guinea, Solomon Islands to Australia.They have a primarily white plumage (in some species tinged pinkish or yellow), an expressive crest, and a black (subgenus Cacatua) or pale (subgenus Licmetis) bill.
The cockatiel is alternatively placed basal to all other cockatoo species, [13] [23] as the sister taxon to the black cockatoo species of the genus Calyptorhynchus [16] [22] [24] or as the sister taxon to a clade consisting of the white and pink cockatoo genera as well as the palm cockatoo. [14]
The male white cockatoo usually has a broader head and a bigger beak than the female. They have brown or black eyes and a dark grey beak. When mature some female white cockatoos can have reddish/brown irises, while the irises of the adult male are dark brown or black. The feathers of the white cockatoo are mostly white.
The Solomons corella (Cacatua ducorpsii), also known as Solomons cockatoo, Ducorps's cockatoo or broad-crested corella, is a species of cockatoo endemic to the Solomon Islands archipelago. This small white cockatoo is larger than the Tanimbar corella yet smaller than the umbrella cockatoo .
The little corella is a small white cockatoo growing to 35–41 cm (14–16 in) in length and weighs 370–630 g (13–22 oz), with a mean weight of 525 g (1.157 lb). [ 5 ] [ 6 ] It is similar in appearance to both the long-billed corella and the western corella , but the little corella is smaller, and unlike either of those species, it has ...
Sulphur-crested cockatoos are 44–55 cm (17.5–21.5 in) long, [6] with the Australian subspecies larger than subspecies from New Guinea and nearby islands. The plumage is overall white, while the underwing and -tail are tinged yellow. The expressive crest is yellow. The bill is black, the legs are grey, and the eye-ring is whitish.
Licmetis is a subgenus of the white cockatoos (genus Cacatua).They are collectively known as corellas in Australia. Three of the six species are primarily – or only – found in Australia, while the Philippines, Indonesia, and the Solomons each have an endemic species.
The species complex was first described by the ornithologist John Latham in 1790 as Psittacus banksii, [4] commemorating English botanist Sir Joseph Banks.The red-tailed black cockatoo also has the distinction of being the first bird from Eastern Australia illustrated by a European, as a female, presumably collected at Endeavour River in north Queensland, was sketched by Banks' draughtsman ...
