Population justification: The population size of this species has not been quantified, but it is generally scarce or rare across most of its range, and only locally common at a handful of sites (Poonswad et al. 2013).
Trend justification: Despite a lack of data on trends, a slow to moderate decline is suspected to be occurring as a result of habitat loss and hunting pressure.
