Population justification: Riley (2003) estimated the population to number 2,350-9,560 individuals, thus here it is placed in the band for 2,500-9,999 mature individuals. This roughly equates to 3,750-14,999 individuals in total, rounded here to 3,500-15,000 individuals.

Trend justification: The species is suspected to be in decline owing to hunting and forest degradation. The likely rate of decline, however, has not been estimated.
