Cockatoos (W)
From WikiBird
A cockatoo is any of the 21 species of bird belonging to the family Cacatuidae. Along with the Psittacidae family ("true" parrots), they make up the order Psittaciformes (all parrots).
Cockatoos share many features with other parrots including the characteristic curved beak shape and a zygodactyl foot (two toes forward and two toes back). They differ however in a number of anatomical characteristics, including the often spectacular movable headcrest, and their lack of the Dyck texture feather composition which gives many parrots their iridescent colours.
Cockatoos as a family have a much more restricted range than the larger parrot group, occurring naturally only in Australia and nearby islands. Of the 21 species, 11 are confined to Australia while 7 species occur in different parts of Indonesia, New Guinea and the Pacific Islands; whereas 3 species occur in both New Guinea and Australia.
