A small genus within the larger Cockatoo family. They are all mostly black in color, and the taxa may be differentiated partly by size and partly by small areas of red, grey and yellow plumage especially in the tail feathers.
They are no longer imported, and though they breed easily, they are uncommon in aviculture in the United States. A hand raised Red Tailed Cockatoo can sell for tens of thousands of dollars. While not great talkers, they can be quite affectionate. All cockatoos are known for having powerful beaks. Most species can crush a brazil nut with ease and tear apart a coconut within a few hours.
Several of the Calyptorhynchus species have been separated into a different genus called Zanda.
