Population justification: The population size has not been quantified, but the species is described as common (Renjifo et al. 2016). Based on the small distribution range, the population is tentatively suspected to number below 10,000 mature individuals; it is therefore here placed in the band 2,500-9,999 mature individuals. This value however requires confirmation, and an accurate estimate of the population size is urgently needed.
Trend justification: The population trend has not been assessed directly. While deforestation has likely been severe in the past (e.g. Renjifo et al. 2016), tree cover loss within the range is currently proceeding at a rate of 2% over ten years (Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). As apart from forests the species also inhabits edges and secondary habitat (Remsen 2020), the current low rate of tree cover loss is unlikely to drive a population decline. In the absence of evidence of any declines or substantial threats, the population is therefore suspected to be stable.
