Fun Facts

The males and females both 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.

These birds are thought to be one of the rarest parrots on Sumba Island.


Ecology and Conservation

Cockatoos are a food source for many predators.

These birds play an important role in seed dispersal and help to regenerate the forest.

These birds are often regarded as pests because their feeding habits are destructive to crops.

Citron-Crested Cockatoos are not as widely sought in the pet trade as other species because they are difficult to breed.

The U.S. Wild Bird Act forbids the commercial import of any bird listed by CITES which includes most parrots. International trade in wild caught Citron-Crested Cockatoos is illegal.
