Population justification: The population is estimated to number 650-1,120 individuals, roughly equivalent to 430-750 mature individuals (P. Widmann in litt. 2016).

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. US$300 in Manila). This resulted in near-total harvest of nestlings and consequently recruitment was extremely low. 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. Widmann in litt. 2012, 2016). 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. 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. Widmann in litt. 2013). 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.
