Sulphur-crested cockatoos are large, bulky birds, with broad rounded wings. They are white with a conspicuous yellow crest on the head, and yellow undersides to the wings.
They are widespread in NE and SE Australia and also throughout much of New Guinea and neighbouring islands.
Sulphur-crested cockatoos inhabit forests, grassland and urban areas, such as parks and gardens.
They feed on seeds of grasses and herbaceous plants including cereals and oilseeds, as well as fruits and flowers, bulbous roots and insect larvae.
Sulphur-crested cockatoos are gregarious, and are seen in pairs, small groups or groups of hundreds. They are noisy birds, and are active in the morning and late afternoon.
They breed all year depending on the location. Both adults incubate a cluch of 2-3 eggs in a tree hollow.
They are not listed by the IUCN.
