Population justification: The global population size has not been quantified, but this species is described as 'uncommon to fairly common' (Stotz et al. 1996).
Trend justification: A moderately rapid and on-going population decline is suspected, owing to hunting for the species's skin and meat as well as the destruction and fragmentation of its habitat.
