Cacatua

Cacatua is a genus of cockatoos found from the Philippines, Indonesia, Papua New Guinea, and Solomon Islands to Australia. They have a primarily white plumage, an expressive crest, and a black or pale bill. Today, several species from this genus are considered threatened due to a combination of habitat loss and capture for the wild-bird trade, with the blue-eyed cockatoo considered vulnerable, Moluccan cockatoo, and umbrella cockatoo considered endangered, and the red-vented cockatoo, yellow-crested cockatoo and citron-crested cockatoo considered critically endangered.

Taxonomy

Although the name Cacatua was used in 1760 by French zoologist Mathurin Jacques Brisson, he did not include it in his table of genera and Brisson is not recognised as the authority by the International Commission on Zoological Nomenclature. The genus Kakatoe was introduced by Georges Cuvier in 1801 but this name has been suppressed by the ICZN and instead Louis Pierre Vieillot is recognised as introducing the genus Cacatua in 1817. The type species was designated as the white cockatoo by Tommaso Salvadori in 1891. The name Cacatua is from the Malay language words Kakatuá and Kakak-tuá for the cockatoos.

The genus contains 13 species.
