Population justification: The global population size has not been quantified, but the species is described as uncommon to locally fairly common (del Hoyo et al. 2005).
Trend justification: This species is likely to be declining in line with rates of deforestation occurring across its range. These declines are suspected to be particularly severe, as this species is largely restricted to mature forests in the flat lowlands, where rates of habitat loss are highest. The overall rate of population decline is therefore suspected to be moderately rapid or rapid.
