The Umbrella Cockatoo, Cacatua alba (also known as the White Cockatoo) is a medium-sized, up to 46 cm long cockatoo endemic to the islands of Halmahera, Bacan, Ternate, Tidore, Kasiruta and Mandiole in North Maluku, Indonesia. At first sight it appears to be a white parrot with brown or black eyes and a dark grey beak. If it is surprised, it extends a large and striking crest, which has a semicircular shape (similar to an umbrella, hence the name). The crest is normally recumbent. The underside of the wings and tail have pale yellow or lemon colour, which flash when they fly.

The Umbrella Cockatoo can live up to, and perhaps beyond, 80 years in age. The Umbrella Cockatoo weighs about 400 grams for small females and up to 800 grams for big males. The male Umbrella cockatoo usually has a broader head and a bigger beak than the female.

During their puberty the female Umbrella cockatoo can begin to develop a more redish iris than the male.

The feathers of the Umbrella 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 colour. The yellow colour is most notable on the underside of the wings 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.

Conservation status

Although the Umbrella Cockatoo is not classified as an endangered species, it is classified as vulnerable. Its number in the wild have declined owing to habitat loss and illegal trapping for the cage-bird trade. It is listed in appendix II of the CITES list of protected species. This gives it protection by making the export, import and trade of wild-caught birds illegal.

Aviculture

Umbrella Cockatoos are often kept as pets because they bond closely with people and are valued for their beauty. They can imitate basic human speech, but are not considered the most able speakers among parrots. They are often used in live animal acts in zoos and amusement parks, because they are naturally acrobatic and easily trained, because of their highly social nature, and high level of intelligence.

Cockatoos do not make ideal pets. They require a lot of time, devotion and understanding from their caregivers. They can destroy furniture and cause serious injury with their powerful beaks. Umbrella Cockatoos shed a white powdery feather dust, which can cause respiratory problems in sensitive humans. Their normal vocalizations are loud enough to cause hearing damage. Like other parrots, Cockatoos are prone to developing neurotic behaviors such as screaming, self-mutilation, and violence toward their caretakers or cagemates, especially as they reach sexual maturity. Cockatoos are often surrendered to rescue organizations, abandoned or euthanized because of these issues. Because of their longevity, these birds may outlive their caretakers.

The high market value of these birds has led to unsustainable levels of harvest for the pet trade. In 1994 the Umbrella Cockatoo was listed as a CITES I endangered species. This species has since been taken off the endangered species list, but is still listed as Vulnerable. Principal threats to this species are the pet trade and loss and degradation of their forest habitat.
