Population justification: Distance sampling along nearly 500 km of line transects at 14 sites across Luzon in 2009-2010, then multiplying site-specific density estimates by reserve area, resulted in estimates of 246 individuals (95% CI: 42-1,434) in Northern Sierra Madre Natural Park, and 174 (95% CI: 80-380) in Subic Bay Forest Reserve/Bataan Natural Park (Española et al. 2013). The data therefore suggest that there are fewer than 250 mature individuals in each of the two main remaining sub-populations and imply that the total population could include fewer than 2,500 mature individuals. The population is therefore placed in the band for 1,000-2,499 mature individuals, assumed here to equate to a total of c.1,500-3,800 individuals.

Trend justification: The threats of widespread logging and trapping for the cage-bird trade suggest that this species is undergoing a rapid population decline.
