The Sulphur-crested Cockatoo (Cacatua galerita) is a relatively large white cockatoo found in wooded habitats in Australia and New Guinea and some of the islands of Indonesia. They can be locally very numerous, leading to them sometimes being considered pests. They are well known in aviculture, although they can be demanding pets.
In Australia, Sulphur-crested Cockatoos can be found widely in the north and east, ranging as far south as Tasmania, but avoiding arid inland areas with few trees. They are numerous in suburban habitats in cities such as Adelaide, Melbourne, Canberra, Sydney and Brisbane. Except for highland areas, they occur throughout most of New Guinea and on nearby smaller islands such as Waigeo, Misool and Aru, and various islands in the Cenderawasih Bay and Milne Bay
