Lesser sulphur-crested cockatoos are the smallest of the sulphur-crested parrots.
Both parents take part in incubating the eggs.
Cockatoos can mimic the sounds of other animals, including people.
Cockatoos can hold their food in one foot and break pieces off of it with the other foot.
Cockatoos live in small, loose flocks.
They are very gregarious and quickly learn to mimic. These birds also have a very shrill cry.
Ecology and Conservation
Cockatoos are a food source for many animals larger than themselves.
Their feeding habits are very destructive, which annoys most gardeners. These birds are often regarded as pests because of their diets (sometimes feeding on crops).
They aid in seed dispersal through their eating of fruit.
Unsustainable collection for the pet trade industry has caused a drastic decline in this species' wild population.
The U.S. Wild Bird Act forbids the commercial import of any bird listed by CITES which includes most parrots, which are endangered or threatened.
