Found in the Andes of southern Colombia, Ecuador, and northern Peru. It prefers humid montane forest, elfin forest, and paramo edge habitats, usually at elevations between 2,500 and 3,800 meters (8,200-12,500 feet).

Its distinguishing features are its small size, greenish-brown upperparts, and often a short, straight bill. While it may lack the bright iridescence of some other hummingbirds, its agile flight and presence in high-altitude habitats can aid identification. Look for it feeding on low-growing flowers or hovering to catch insects.

Year-round resident, active during daylight hours. Observation is generally best in the mornings when nectar sources are plentiful and light conditions are good.
