Cockatoos

Distribution
Cockatoos have a much more restricted range than the true parrots, occurring naturally only in Australia, Indonesia, the Philippines, and some Pacific regions.
Diet
Cockatoos are versatile feeders and consume a range of mainly vegetable food items. Seeds form a large part of the diet of all species; these are opened with their large and powerful bills.
Information

Some species require roosting sites that are located near drinking sites; other species travel great distances between the roosting and feeding sites.Cockatoos have several characteristic methods of bathing; they may hang upside down or fly about in the rain or flutter in wet leaves in the canopy. Cockatoos have a preferred "footedness" analogous to human handedness. Most species are left-footed with 87–100% of individuals using their left feet to eat, but a few species favor their right foot.
