![]() The Umbrella Cockatoos and the Moluccan Cockatoos have the largest and fullest crests. The Umbrella Cockatoos was named for its broad, backward-bending crest, which open like an umbrella and fan out. Umbrella Cockatoos are large white parrots with brown / reddish or black eyes, dark grey beaks and legs. (Arndt and Pittman, 2003 Juniper and Parr, 1998) Their wings measure between 9.84 – 12.2 inches or 25 to 31 cm. They average 18 inches or 46 cm in length. Umbrella Cockatoos are medium-sized cockatoos that weigh between 17 oz (480 g) up to 25 oz (700 g) – the average being 20 oz (565 g). There are some claims that some of them have lived to the ripe of age of 100, but this has not been verified. Umbrella Cockatoos can live over 40 years in captivity and 30 years in the wild. This gives it protection by making the trade of wild caught birds illegal. It is listed in Appendix 2 of the CITES list of protected species. It numbers in the wild have declined owing to habitat loss, hunting and illegal trapping for the cage-bird trade. Umbrella Cockatoos, like all the other species of cockatoos, are important for the dispersal of seeds - which has important consequences for the ecology and evolution of plants.Īlthough the umbrella cockatoo is not classified as an endangered species it is classified as vulnerable. They are particularly common along the edges of clearings and rivers. Within their natural range, they are found at elevations of 1,000 to 3,000 ft (300 to 900 m) in a variety of habitats, including forests and open woodland, mangroves, swamps and agricultural areas (where they are considered “pests” since they feed on the crop). (BirdLife International, 2001 Juniper and Parr, 1998) They are also found on the island of Obi and the nearby island of Bisa, but it is believed that they were introduced to these islands and are escaped pets. Specifically, they occur naturally on the islands of Bacan, Halmahera, Tidore, Kasiruta, Ternate, Kasiruta and Mandioli. To prevent the cloacal prolapse from occurring again, the bird has to stop thinking of the owner as its parent or mate.The Umbrella Cockatoo or White Cockatoo, Cacatua alba, is endemic to the islands of Central and Northern Moluccas (aka Maluku Islands) in Indonesia. Owners are advised to break the close bond for the good health of the bird and not stroke the bird on the back, feed it by hand, or cuddle the bird close to the body. Treatment is done via surgery and behavior modification therapy. Successful treatment depends on timely detection. It also occurs in birds that have a habit of holding in the stool for long periods of time, like overnight, instead of dropping it as it is comes to cloaca.Īny combination of the above reasons can lead to straining, dilating and stretching of the vent, making the bird an ideal candidate for cloacal prolapse. The misplaced sexual attraction towards the person also causes stretching and opening of the vent. Such birds will hold feces for long time, and also cry out for food thus repeatedly strain their cloaca and vent in the process. Birds who are extremely attached to one person and recognizing the person as either a mate or a parent also have a higher chances of having cloacal prolapse. Hand raised and hand fed birds with delayed weaning show a greater tendency towards cloacal prolapse. ![]() Usually the reasons are both physical and behavioral. CausesĬloacal prolapse occurs when long-term strain is put onto the vent. However, cockatoos not bred by humans are not affected by cloacal prolapse. ![]() Mature Umbrella and Moluccan cockatoos suffer more often from cloacal prolapse, as do hand-fed birds. The cloacal lips (or vent) are used to control the passage and frequency of droppings and other eliminations. ![]() The cloaca is the part of the bird’s body which stores urates, feces, urine and egg. Cloacal prolapse or vent prolapse is a condition where the inner tissues of the cloaca protrude (hang out) from the vent, exposing the intestines, cloaca or uterus.
