Subpopulations away from Palawan and the Sulus are mainly tiny and have few long-term prospects. 2016), it is possibly extinct on Mindanao, and there are fewer than 20 individuals recorded in the Polillo group of islands, Bohol and Samar (P. Of these, there are 580-850 on Palawan and its satellite islands, several hundred or 50-150 in Sulu (I. In 1950, it was common throughout but a rapid decline has left a population of c. This species is endemic to the Philippines. Therefore although they have now slowed or even stopped, declines are suspected to have been >80% in the past three generations (39 years), and as such the current trend is tentatively retained as declining. Interviews with trappers and farmers indicate that Philippine Cockatoos were considerably more common at least until the early 1980s in Palawan, Mindoro, Polillo, Mabate, Samar, Bohol, and Siargao, indicating that the dramatic decline occurred later in this decade (P. In five PCCP (Philippine Cockatoo Conservation Program) project sites, it has recovered considerably, but declines elsewhere continue, notably in Polillo, and it is feared nearing extinction in Rizal. ![]() However, the current population trend may in fact be far more favourable, since many populations in the oceanic Philippines are extinct and some protected populations are increasing (P. This resulted in near-total harvest of nestlings and consequently recruitment was extremely low. Trend justification This long-lived species has declined extremely rapidly owing to extensive deforestation within its range, but also as a result of the high prices the birds fetch in trade (c. Population justification The population is estimated to number 650-1,120 individuals, roughly equivalent to 430-750 mature individuals (P. However, the bulk of the past declines are believed to have occurred within the past three generations and so it is assessed as Critically Endangered. ![]() Now that it is extinct in much of its historic range, and some protected populations are increasing, the rate of decline may have slowed or the decline may even have stopped. Justification of Red List category This species has suffered an extremely rapid population reduction owing to extensive loss of its lowland habitats and trapping for the cagebird trade.
