Cacatua galerita

CACATUIDAE

Sulphur-crested Cockatoo

Description
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 in the male). This is a noisy and conspicuous cockatoo, both at rest and in flight. Young Sulphur-crested Cockatoos resemble the adults.
Feeding
The Sulphur-crested Cockatoo's normal diet consists of berries, seeds, nuts and roots. It also takes handouts from humans. Feeding normally takes place in small to large groups, with one or more members of the group watching for danger from a nearby perch. When not feeding, birds will bite off smaller branches and leaves from trees. These items are not eaten, however. The activity may help to keep the bill trimmed and from growing too large.
Breeding
The eggs are laid in a suitable tree hollow, which is prepared by both sexes. Both birds also incubate and care for the chicks. The chicks remain with the parents all year round and family groups will stay together indefinitely.
Calls
The most common call is a distinctive loud screech, ending with a slight upward inflection.
