Cockatoos have a much more restricted range than the true parrots, occurring naturally only in Australasia. Eleven of the 21 species exist in the wild only in Australia, while seven species occur only in the islands of the Philippines, Indonesia, Papua New Guinea and the Solomon Islands. Interestingly, no cockatoo species are found in Borneo (despite their presence on nearby Palawan and Sulawesi) or many Pacific islands, although fossil remains have been recorded from New Caledonia.
