Population justification: The global population size has not been quantified, but the species is described as fairly common to uncommon, although locally rare to uncommon in several countries (Thewlis et al. 1998, Gibbs et al. 2001, Goes 2013).

Trend justification: No trends data area available, but the population is suspected to be undergoing a moderately rapid decline owing to the effects of habitat loss (especially as the species may be a lowland forest specialist), and hunting pressure.
