Population justification: The global population size has not been quantified, but the species is described as usually rather scarce or rare (Gibbs et al. 2001).

Trend justification: There are no data on population trends; however, the species is suspected to be in moderately rapid decline, owing to habitat loss and degradation, and hunting.
