Population justification: The global population size has not been quantified, but the species is reported to be fairly common to common in most of its range (Wells 1999, del Hoyo et al. 2002).

Trend justification: Remote sensing data (Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein) indicate that forest cover loss in this species range has been 25-30% over the past three generations (11.1 years; Bird et al. 2020). Although this species is suspected to occur at higher densities in primary and selectively logged forest than plantations, it does occur in the latter (Wells 1999) such that the rate of decline is suspected to be no higher than that of forest loss, and so is suspected to be 20-29% over three generations. The declines are suspected to continue at a similar rate into the future.
