These small, bronzy green hummingbirds inhabit only a small area in southern Ecuador and northern Peru, where they are considered Near-Threatened. "Neblina" is Spanish for "mist"; Neblina Metaltails occupy the mist shrouded borders of elfin forests near grassy slopes, in areas with forested ravines, and around shrub-filled páramo. Unlike several other hummingbirds that occupy similar habitat, Neblina Metailtails remain active in the same habitat year-round, even during extreme weather. They forage at all heights and males are territorial around flowers. Both males and female Neblina Metaltails have deep reddish throat patches, but that of the male is more extensive.
