The Sulphur-crested Cockatoo is a large white parrot. It has a dark grey-black bill, a distinctive sulphur-yellow crest and a yellow wash on the underside of the wings. Sexes are similar, although the female can be separated at close range by its red-brown eye (darker brown-black in the male). This is a noisy and conspicuous cockatoo, both at rest and in flight. Young Sulphur-crested Cockatoos resemble the adults.
45 - 50 centimetres in length and weighs approximately 830grams.
The Sulphur-crested Cockatoo’s diet consists of berries, seeds, nuts and plant roots.
Sulphur-crested Cockatoos are found in a variety of timbered habitats and are common around human settlements. The birds stay in the same area all year round.
Sulphur-crested Cockatoo’s are found throughout the northern and eastern mainland, and Tasmania. A small population has become established around Perth, Western Australia.
Breeding season in the south is August to January and May to September in the north. The eggs are laid in a suitable tree hollow, which is prepared by both sexes. The female will lay 1-3 eggs and both sexes share the incubation process, which is approximately 30 days. The chicks remain with the parents all year round and family groups will stay together indefinitely.
