Cacatuidae

Cacatuidae is the cockatoo family of parrots, order Psittaciformes, comprising 22 species native to Australasia, from the Philippines and the eastern Indonesian islands of Wallacea to New Guinea, the Solomon Islands and Australia. Cockatoos are recognizable by their prominent crests and curved bills, and their plumage is generally less colorful than that of other parrots, running mainly to white, grey or black with colored features on the crest, cheeks or tail. Most cockatoos are larger than other parrots, though the cockatiel is a notably smaller and slimmer exception.
