Population justification: The population is estimated to number 320-340 individuals, based on an area of habitat of 6 km2. This is interpreted by Kinnaird and O'Brien (2007) to equate to fewer than 250 mature individuals, and so the population is placed in the band 50-249 mature individuals.
Trend justification: Its population appears to be stable despite some degree of hunting and habitat degradation.
