The Greater Sulphur Crested Cockatoo is a fairly common bird in lowland forests and savannah country. In Australia they are common inhabitants of forests, open wooland and farmland. They are noisy, conspicuous birds. Usually found in pairs or small family parties during the breeding season, at other times they are found in flocks of several hundred. Whenever they frequent open countryside they have a sentinel warning system. A few birds remain perched at the top of trees while the flock feeds on the ground below. At the approach of danger the sentinels rise into the air screeching loudly. The rest of the flock are warned and they too rise into the air.

They feed on seeds, fruits, berries, nuts, flower, leaf buds, roots as well as insects and their larvae. They are known as pests in crop-growing areas, although they do eat a considerable amount of weed seeds as well.
They nest in a hollow limb or tree trunk, generally high up and frequently near a water source. The normal clutch is 2 eggs.
The adult Greater Sulphur Crested Cockatoo is mostly white. They have a large forward curving crest which is yellow. Like the Lesser Sulphur Crested they have yellow under their wings and tail, this is easily seen when they are in flight. Their beak is black and their eye rings are white.
