Northern Australia from West Australia to the Gulf of Carpentaria Restricted to the Aru Islands in the Maluku province of eastern Indonesia 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.įound in New Guinea and the surrounding islands They are numerous in suburban habitats in cities such as Adelaide, Melbourne, Canberra, Sydney, Brisbane and Perth. In Australia, sulphur-crested cockatoos can be found widely in the north and east, ranging from the Kimberley to as far south as Tasmania, but avoiding arid inland areas with few trees. ![]() A highly intelligent bird, they are well known in aviculture, although they can be demanding pets. They can be locally very numerous, leading to them sometimes being considered pests. The sulphur-crested cockatoo ( Cacatua galerita) is a relatively large white cockatoo found in wooded habitats in Australia, New Guinea, and some of the islands of Indonesia. While they can adapt to new food sources such as pine nuts from introduced trees, they need old-growth forests with hollow trees for nesting.Sulphur-crested cockatoo range (in red), introduced range (in violet) ![]() These birds migrate seasonally they spend summers in high-altitude areas, moving to warmer lowland areas in winter. Several pairs may nest close together, and their young aggregate in ‘creches’ while their parents are out foraging. Breeding takes place between October and January females lay up to 3 eggs in tree-hollow nests, and both parents incubate and rear the young. Males and females pair for life and will often return to the same nesting tree each year. This late start limits the rate at which populations can build up, which is another conservation concern. Gang-gang Cockatoos begin breeding at four years of age. They are locally common within their distribution but are experiencing a worrying decline. Like other cockatoos, Gang-gangs are noisy, conspicuous, gregarious birds with curved beaks for crushing seeds. Females have reddish feathers on their undersides. Their mottled grey plumage contrasts with the shock of crimson feathers on the heads of male birds. Gang-gang Cockatoos are sturdy, medium-sized birds with short tails and broad wings. They inhabit cool, wet forests, particularly alpine bushland, but may visit urban parks and gardens to feed. Gang-gang Cockatoos are found in south-eastern Australia. weigh on average 257 g and are 32–37 cm with a wingspan 62–76 cm.are omnivores and they eat seeds of native and introduced trees and shrubs, berries, fruits, nuts and insects.probably look similar to early, primitive cockatoos.have a call that sound like a creaking gate, or a cork being pulled from a bottle.often return to the same nesting tree each year. ![]() In combination these factors present a serious threat to Gang-gang Cockatoos in the medium and long term. This species is also susceptible to psittacine circovirus disease which causes feather loss and beak abnormalities. Land clearing and the removal of old trees endangers Gang-gang Cockatoos because they lose their feeding habitat and breeding hollows. ![]()
