Greater Sulphur-Crested Cockatoo

The Greater Sulphur-Crested Cockatoo (Cacatua galerita galerita) is a large bird from northern, eastern, and southern Australia.

The Greater Sulphur-Crested Cockatoo is white, except for the underwing, undertail, and crest, which are yellow. Males have black eyes, and females have red or brown eyes. It has a white eye-ring, black beak, and grey legs. Instead of oil on their feathers for waterproofing, it has a fine powder called pulviplume.

It grows to about 44–55 centimetres (17–21 inches) tall.

It can be found from Cape York in the north to Tasmania in the south. It prefers tropical forests, subtropical forests, and woodlands.

The Greater Sulphur-Crested Cockatoo has a loud screech. They are curious and intelligent.

It feeds on seeds and grains on the ground. While the flock of cockatoos feed, one cockatoo keeps guard in a tall tree. The guard will screech loudly to protect the flock from predators, such as dogs.

It makes a nest in the hollow of a tree. Females lay 2-3 eggs, which take 25-27 days to hatch. Both parents sit on the eggs, and feed their newly-born chicks. The chicks stay in the nest for 9-12 weeks, before they can fly, and will stay near their parents for a few months.

The Greater Sulphur-Crested Cockatoo can live for about 70 years in captivity and 20-40 years in the wild.
