Population justification: The population has been estimated at 77-231 individuals, with a total population unlikely to exceed 200, based on population density estimates derived from surveys carried out in selected areas of the species's range (Hayes et al 2009). The population size is therefore placed in the band 50-249 mature individuals.

Trend justification: This species's population has declined in line with levels of hunting, habitat loss and habitat degradation within its range. The tiny remaining population is not well protected and declines are assumed to be continuing.
