Population justification: Del Hoyo et al. (1992) estimate that the population is likely several hundred thousand individuals. Therefore, the population is tentatively placed here in the range 100,000-499,999 individuals.
Trend justification: The population is suspected to be in decline owing to ongoing habitat destruction and unsustainable levels of exploitation.
