Population justification: The total population has been conservatively estimated at 28,000 birds.
Trend justification: The population is suspected to be in decline owing to the clearance and degradation of the species's forest habitat through the encroachment of agriculture and wood extraction. The likely rate of decline, however, has not been estimated.
