Population justification: The global population size has not been quantified, but this species is described as uncommon and local to fairly common (Stotz et al. 1996, Remsen 2020).
Trend justification: Due to its dependence on forested habitat, the species is assessed as undergoing a decline as forests are lost, fragmented and degraded.
Over ten years, 6% of tree cover is lost within the range (Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). Due to its susceptibility to severe logging (Remsen 2020), population declines may be steeper than the rate of tree cover loss suggests. Tentatively, the rate of decline is here placed in the band 1-19% over ten years.
