Population justification: The global population size has not been quantified, but the species has been described as 'fairly common' (Stotz et al. 1996). However, based on its restricted range and observational records (per eBird 2021), it is suspected that the population may be moderately small; it is here placed in the band 10,000-19,999 mature individuals.

Trend justification: The species is suspected to be undergoing a slow decline due to habitat loss and degradation. Tree cover loss within the species range equates to c. 4% over ten years (Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). The species is however restricted to the elevational belt across the Andean foothills (Snow 2020) and is highly dependent on forest cover. Therefore, due to its possible niche habitat requirements, the species may undergo declines beyond the rate of tree cover loss alone, and as such, it is assumed that the population is undergoing a decline of 1-9% over 10 years.
