Cockatoos have long life spans, from 30 to 50 years, and some have survived in captivity for 60 to 70 years. All cockatoos have a bald spot on their head, covered by a crest of feathers. They have a down powder beneath their feathers which provides them with insulation to keep them warm. The down also sheds a thick powder, which the birds use to waterproof and clean their outer feathers. Cockatoos are the only parrots to have powder down.
Cockatoos are very intelligent birds, and can be quite comical.
Their life cycle is similar to that of humans. They go through infancy, childhood, adolescence, young adulthood, middle age, and old age. They can even be trained to talk, though their voice is much higher pitched than that of other parrots. You may think that all cockatoos are white birds with yellow crests, but there are many species of cockatoo. There are even black cockatoos, but they are rare, and most of them live in wildlife parks and zoos.
