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 parrot clan, 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 are 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, cockatoos are larger than parrots, though there are exceptions.
