Population justification: The global population size has not been quantified, but the species is described as generally common (del Hoyo et al. 2005).

Trend justification: This species is assumed to be declining moderately rapidly because it occurs in lowland forest which is decreasing in extent and quality owing to logging pressure, and it may suffer from hunting pressure which may increase in the future.
