Population justification: The population size is preliminarily estimated to fall into the band for 10,000-19,999 mature individuals. This equates to 15,000-29,999 individuals in total, rounded here to 15,000-30,000 individuals.

Trend justification: Forest habitat has been extensively cleared in much of the Sierra Madre and Cordillera Central mountain ranges of Luzon; together with hunting pressure, this is suspected to be causing a moderately rapid decline in the species's population.
