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.
