Population justification: Estimated the population size of this species is extremely difficult owing to the paucity of records, despite increasingly good coverage of its range. Contemporary records are from three main islands: Luzon, Mindoro and Mindanao, with no recent records from Sibuyan and Siquijor (eBird 2022). For a long time, thought to be extirpated on Mindoro (Collar et al. 1999) but recent records of up to 25 individuals suggest the island does continue to support a small viable population, although the area of suitable forest and the number of observations suggest it is unlikely to be more than c.200 mature individuals. On Luzon and Mindanao, there are many recent records but these are temporally variable and the species appears to move widely in search of food such that the total number of individuals is estimated to be small. Based on the number of birds sighted in any block of forest (eBird 2022), the number of mature individuals on each of Luzon and Mindanao is estimated at 500-1,500, although this requires confirmation by specific surveys.
Trend justification: Forest loss and hunting has caused this species to be extirpated from area it formerly occupied (e.g. Siquijor and Negros). Both of these threats are ongoing. Forest cover loss in this species' range in the three generations to 2022 totalled c.10% (Global Forest Watch 2022, based on data from Hansen et al. [2013] and methods disclosed therein) and this is likely to be the minimum population reduction because of additive hunting pressures. The ongoing rate of decline is therefore suspected to be 10-19% over three generations (c.18.5 years; Bird et al. 2020).
