Cockatoos are active during the day, and may roost communally at night. This provides them with more safety from predators. In the wild, cockatoos eat various kinds of fruit, seeds and insects. Their diet at the zoo includes vegetables, fruit, and commercial parrot pellets. Sexual maturity is reached between 2 and 4 years of age.
Clutches usually consist of two white eggs.
The parents incubate the eggs for about three weeks. Cockatoos usually nest in holes in the limbs or trunks of trees. Both parents play an equal role in caring for the young. Many species are on the brink of extinction. Another major threat is the voracious pet trade.
