The sulphur-crested cockatoo is a large white parrot with a distinctive sulphur-yellow crest, and is one of Australia's most well-known birds.
In the north, sulphur-crested cockatoos live in pairs or small groups. In the south, they live in large flocks. They feed on seeds, grains, roots, berries, nuts and leaf buds.
Cockatoos, along with some other parrots, have the most evolved brains in all birds. They became easily habituated among people, and can imitate all sorts of noises, including human words. They are often kept as pets, as they are extremely intelligent and very good at learning to talk.
Sulphur-crested cockatoos are highly social. They are also monogamous breeders, and will bond with a mate for several years, or even life.
