Population justification: The global population size has not been quantified, but this species is described as reasonably common but easily overlooked (Schulenberg and Kirwan 2020). It therefore likely numbers far more than 10,000 mature individuals.
Trend justification: The population trend has not been investigated, but declines are suspected on the basis of habitat loss.
Tree cover loss within the range is c. 5% over ten years (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). Habitat degradation may additionally compound population declines above the rate of tree cover loss alone, albeit reduction rates are not thought to exceed 10%, and hence are here tentatively placed in the band 1-9% over ten years.
