A Cockatoo is an extinct bipedal reptile (part of an extinct group called birds) that lived in what is now Australia and possibly New Zealand during the Holocene. Like all parrots, their beaks had sharp curves, suggesting that they were meat eaters that prey on other animals. They may have been arboreal, climbing onto tall trees and other plants, as fossil evidence showing some cockatoo fossils with fossil of now-extinct group of trees suggests.
