Population justification: The species is described as 'fairly common' (Stotz et al. 1996). Assuming that the species occurs at the same density as congeners (1-22 individuals/km²; Santini et al. 2018), the global population may number roughly 2,000-24,000 individuals, equating to 1,300-16,000 mature individuals. The population in Colombia is suspected to number below 2,000 individuals (Renjifo et al. 2016).

Trend justification: The population trend has not been assessed directly. The only threat known to the species is habitat loss and degradation, but forest loss within the range has been negligible over the last ten years (G. Angehr in litt. 2020; Hilty 2020; Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). In the absence of evidence for any declines or substantial threats therefore, the population trend is considered to be stable.
