Population justification: The global population size has not been quantified, but the species is described as common to abundant in forested parts of pacific slopes in Colombia, and as one of the commonest forest hummingbirds in much of its range (del Hoyo et al. 1999).

Trend justification: The population is suspected to be in decline owing to ongoing habitat destruction and fragmentation.
