Justification of Red List category
Although this species may have a small range, it is not believed to approach the thresholds for Vulnerable under the range size criterion (extent of occurrence <20,000 km² combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations) (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Population justification
The global population size has not been quantified due to recent taxonomic splits. Prior to being split, the species was described as 'fairly common' (Stotz et al. 1996) and 'over most parts of range one of the commonest mountain hummingbirds' (del Hoyo et al. 1999).

Trend justification
Forested habitat within the range is currently not under threat (Global Forest Watch 2021), therefore in the absence of any declines the population is suspected to be stable.

Conservation Actions Proposed
Quantify the population size. Monitor the population trend.
