Population justification: The population was estimated to be not more than 1,000-2,000 pairs (2,000-4,000 mature individuals) in the early 1980s, and there has not been a more recent assessment. This estimate is roughly equivalent to 3,000-6,000 individuals in total.

Trend justification: The population is suspected to be declining at a moderate rate in line with the clearance and degradation of its forest habitat.
