Population justification: The population is inferred to number 1,000-2,499 individuals based on an assessment of known records, descriptions of abundance and range size. This is consistent with recorded population density estimates for congeners or close relatives with a similar body size, and the fact that only a proportion of the estimated Extent of Occurrence is likely to be occupied. This is roughly equivalent to 667-1,666 mature individuals, rounded here to 600-1,700 mature individuals.

Trend justification: The population trend has not been estimated directly. The only threat known to the species is the loss of its habitat; yet forest loss within the range has been very low over the past ten years (< 1%; Global Forest Watch 2020). However, models revealed that available habitat in the species’s altitudinal range will decrease by c. 24% across Ecuador and Colombia by the end of this century (Renjifo et al. 2014). Therefore, the species is tentatively suspected to be in a slow decline, the rate of which is not thought to exceed 10% over ten years.
