Taxonomy

Taxonomic note

Lampornis castaneoventris and L. cinereicauda (del Hoyo and Collar 2014) were previously lumped as L. castaneoventris following SACC (2005), which in turn was previously lumped with L. calolaemus as L. castaneoventris following Sibley and Monroe (1990, 1993).

Population justification: The global population size has not been quantified, but this species is 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: The population trend is difficult to determine because of uncertainty over the impacts of habitat modification on population sizes.
