Sulphur-crested cockatoo

The Yellow-crested Cockatoo (Cacatua galerita) is a species of bird in the family Cacatuidae. It is one of the largest and most widespread Australian cockatoos. It is frequently sought after as a pet in and out of Australia. But, in freedom, it is often slaughtered and poisoned because considered as harmful. Indeed, in bands or solitary, it can attack cereal and fruit crops, as well as the wood of trees, garden sheds or houses. However, to destroy them, authorization from the Australian government because they are protected animals.

Description

It is an animal measuring 45 to 50 cm in length and weighing 800 to 900 g. Its plumage is white, with a large erect hoop facing rear at rest, of a strong yellow. The underside of the wings and tail is light yellow. It has a very dark gray, almost black bill. The two sexes are similar although the female is smaller and the eyes are not quite the same color: brown to red in the female, black in the male. It is a noisy animal both in flight, in the morning and in the evening when it is going to feed, and at rest.

BEHAVIORS IN WILDLIFE:

The crested cockatoo Sulphur-crested cockatoo is common in most of its habitat. Outside the breeding season, these noisy birds congregate in large groups to feed on meadows, bushes, and trees. They feed on seeds, fruits, hearts of palm trees and insects. They can hold their food with the fingers of one leg, while with the other they break or tear off pieces.

They are sometimes seen as pests for crops, and farmers kill or poison them. While the group feeds on the ground, several birds remain perched in the neighboring trees and watch the surroundings to alert the group in case of danger. If a predator or an intruder approaches, they give their raucous and loud cries.
They sleep in a common dormitory where you can find several hundred birds. They return there every evening at dusk.

During the breeding season, the crested cockatoo is often seen in pairs or small family groups. At midday, they shelter in the shade in the nearby trees with which they damage the leaves and bark, enough for the loss of foliage to destroy the tree.

Southern birds tend to feed on the ground, while northern birds are more arboreal. They become common around human habitations where they are parasites that use their powerful beak to destroy panels or other parts of houses.

The courtship display is simple. The male struts along a branch of a tree towards the female. He erects his crest, swings his head up and down and from side to side, forming an “8”. At this time, it emits a soft chatter and the two partners practice the mutual smoothing of the feathers and the “beak to beak”.

FLIGHT :

The crested cockatoo flies with rapid, shallow beats interspersed with glides. It can fly very high, descending by sliding in large swirling circles to land.

REPRODUCTION OF THE SPECIES:

The breeding season takes place from August to January in the south, and from May to September in the north.
The Crested Cockatoo Sulphur-crested cockatoo nests in tree holes, especially in large Eucalyptus trees, and usually near water. Both sexes prepare the nest. They are monogamous.

The female lays 1 to 3 white eggs. The incubation lasts about 30 days, shared by the two adults. The chicks are nestlings and are fed by the parents. They abandon the nest after 60 to 70 days. They stay with their parents all year round. Family groups can stay united for a long time.

FOOD :

The crested cockatoo feeds on berries, seeds, hazelnuts and nuts and roots.
When it is not feeding, it nibbles on small branches and the leaves of trees. He does not eat them but this activity keeps the beak in good condition and prevents it from increasing too much in volume.

PROTECTION / THREATS / STATUS:

The crested cockatoo is a very popular cage bird, but many birds escape and become parasites in urban areas.
Like many other parrots, the crested cockatoo is vulnerable to a widespread virus that causes feather loss and grotesquely enlarges the beak.
The crested cockatoo is considered a pest by farmers who kill and poison it. However, these birds are generally common in their habitat.
