Sulphur_crested.JPG (47461 bytes)Sulphur Crested Cockatoo (Cacatua galerita): is a large bird between 455 and 510 millimetres long. The body is pure white with a plain yellow crest. There is a pale yellow mark on the cheeks. The undertail and underwings are pale yellow.

Sulphur Crested Cockatoos may be observed singly, in pairs or large flocks that whiten the ground when feeding. They are very noisy especially when in flight.

Sulphur Crested Cockatoos occupy varied habitats including rainforests, eucalypt forests and woodlands, grasslands, farmlands and crops.

They nest in eucalypt hollows on decayed debris. Two to three eggs are laid and they are white and oval.

Sulphur Crested Cockatoos are found in northern Western Australia and the Northern Territory, through Queensland, New South Wales, Victoria, South Australia and Tasmania.

Their populations have increased dramatically since European settlement. The growth of cereal and sunflower crops has provided this species and other Cockatoos with an abundant food source.

Sulphur Crested Cockatoos have become troublesome in some urban areas. They seem to have a liking for Western Red Cedar timber and in some areas of Sydney they have demolished cedar-built balconies. A few years ago they attacked the waterproof membrane on the roof of the Herbarium building in Sydney Royal Botanic Gardens.

They do not visit Yallaroo but we sometimes see and hear single birds or pairs flying over.
