The Red-vented Cockatoo, Cacatua haematuropygia, is a species of cockatoo that is endemic to the Philippines; hence it is also known as the Philippine Cockatoo. Called by many names locally (e.g. Abukay, Agay, Kalangay, Katala, etc), this bird used to be found in wild abundance throughout the country's coastal mangrove and lowland forest areas; until the 1980's when its number started to conspicuously decline.
Cage-bird trade and the wanton destruction of its natural habitat are the main culprits of the Philippine cockatoo's diminishing population which is now pegged as just about 1,000 individuals (from a 'high' of 4,000 in the 1990's) found mostly in Palawan, and a few in Masbate, Mindanao and Tawi-tawi.
The Philippine cockatoo is listed as a critically endangered species by the IUCN; and is protected by Philippine law under the Wildlife Conservation and Protection Act (Republic Act 9147).
