1. The greater sulphur-crested cockatoo is the largest of the sulphur-crested group.
2. These birds are often regarded as pests because of their diets (sometimes feeding on crops); licensed culling is permitted in certain states.
3. Both parents take part in incubating the eggs.
4. Cockatoos can mimic the sounds of other animals, including people.
5. Cockatoos can hold their food in one foot and break pieces off of it with the other foot.
6. Cockatoos live in small loose flocks.
7. They are very gregarious and quickly learn to mimic. These birds also have a very shrill cry.


Cockatoos are a food source for many animals larger than themselves.

Their feeding habits are very destructive, which annoys most gardeners.

Cockatoos aid in seed dispersal through their eating of fruit.

This species is very popular in the pet trade and is considered to be an exceptionally easy bird to tame. They are generally very affectionate toward humans and have lively personalities. This species is often used for show and appears quite comfortable in exhibition halls among hundreds of other birds and large crowds. One word of caution: since these birds live a long time, owners often have to will them to someone else in case they are unable to care for them any longer.

The U.S. Wild Bird Act forbids the commercial import of any bird listed by CITES which includes most parrots - endangered or threatened.
