A
cockatoo is any of about 20
species of
bird belonging to the
family Cacatuidae, one of the two families making up the
order Psittaciformes, which includes all
parrots.
Like other members of the Psittaciformes, cockatoos have a characteristic curved beak shape, a zygodactyl foot (two toes forward and two toes back), and many other common features.
Cockatoos differ in their distribution, all being confined to
Australia and the nearby islands, and in a number of anatomical characteristics, including the often spectacular movable headcrest, and their lack of the Dyck texture feather composition which gives many of the parrots their iridescent colours.
In general, most cockatoos are larger than most parrots, though there are exceptions.
