A bird belonging to the parrot family, Psittacidae, and occurring in Australia, New Guinea, and some adjacent islands.
Cockatoos are noisy, and live in groups ranging from a few to a large number of birds.
They feed primarily on seeds, and the galah and the little corella, Cacatua sanguinea , sometimes do considerable damage to grain and rice crops. They nest in large holes in trees, laying two to three round white eggs. The Macmillan Encyclopedia 2001 2. The Macmillan Encyclopedia 2001 3. All rights reserved.
