The White Cockatoo, Cacatua alba (also known as the Umbrella Cockatoo or U2), is a medium-sized, approximately 46-cm-long cockatoo endemic to the islands of Halmahera, Bacan, Ternate, Tidore, Kasiruta and Mandiole in North Maluku, Indonesia. It is a white parrot with brown or black eyes and a dark grey beak. When surprised, it extends a large and striking crest, which has a semicircular shape (similar to an umbrella, hence the alternative name). Pet White Cockatoos may raise their crests upon training, or when something catches their interest such as a new toy or person. The undersides of the wings and tail have a pale yellow or lemon color which flashes when they fly. The White Cockatoo can live up to, and perhaps beyond, 80 years. The White Cockatoo is 48± cm (19 in) long, and weighs about 400 grams for small females and up to 800 grams for big males. The male White Cockatoo usually has a broader head and a bigger beak than the female. During puberty, the female White Cockatoo can begin to develop a more reddish iris than the male. The feathers of the White Cockatoo are mostly white. However, both upper and lower surfaces of the inner half of the trailing edge of the large wing feathers are a yellow color. The yellow color on the underside of the wings is most notable because the yellow portion of the upper surface of the feather is covered by the white of the feather immediately medial (nearer to the body) and above. Similarly, areas of larger tail feathers that are covered by other tail feathers – and the innermost covered areas of the larger crest feathers – are yellow. Short white feathers grow from and closely cover the upper legs.
