Population justification: The global population size has not been quantified, but the species is reported to be frequent to locally abundant (del Hoyo et al. 1997).

Trend justification: The population is suspected to be in decline owing to ongoing habitat destruction and some hunting pressure (Gibbs et al. 2001).
