Population justification: The global population size has not been quantified, but the species is described as common throughout its range, although locally uncommon or rare (del Hoyo et al. 2005).

Trend justification: The population is suspected to be in decline owing to ongoing habitat destruction and fragmentation as well as hunting pressure (del Hoyo et al. 2005).
