Population justification: Bueser et al. (2003) estimated the population on Mindanao to number 82-233 pairs. Numbers elsewhere are tiny: perhaps six pairs on Samar, two on Leyte and probably very few on Luzon, giving a total population size of perhaps 90-250 pairs, or 180-500 mature individuals, roughly equating to 250-750 individuals in total.
Trend justification: An extremely rapid decline is suspected to have taken place over the last three generations, based on rates of habitat loss in the past (given this species's presumably long generation length), which are on-going.
