Population justification: The species strongholds appear to be Luzon and Mindanao where 200-220 pairs and 320-340 pairs respectively were recently estimated. Therefore, the global population is probably best placed in the band 1,000-2,499 individuals. This equates to 667-1,666 mature individuals, rounded here to 600-1,700 mature individuals.
Trend justification: The species is suspected to be declining rapidly, owing to the on-going loss and conversion of its forest habitat for logging and plantation agriculture.
