The family of Cockatoos is native to the Australasian region and extends in the north to the Philippines. The body length is between 30 cm and 65 cm. Cockatoos have curved beaks and a partially showy crest. The middle two of the toes point forward, the two outer ones backward. In contrast to the other parrots, the plumage does not have the bright colors blue and green, because the feathers lack the Dyck texture. They colonize practically all available habitats. All species are diurnal and sociable. Most species mainly eat seeds, a few mainly insects. Cockatoos are monogamous and breed in tree hollows, which they cannot create on their own. Depending on the species, they lay between 1 and 8 eggs in it. The young are altricial.
