Population justification: Delacour & Amadon (2004) estimated the population size to number fewer than 10,000 mature individuals, thus the population is placed in the band 2,500-9,999 mature individuals. This equates to 3,750-14,999 individuals in total, rounded to 3,500-15,000 individuals here.

Trend justification: A rapid and on-going population decline is suspected on the basis of hunting pressure and habitat degradation.
