Widespread across the Andes, from northern Venezuela through Colombia, Ecuador, and Peru, south to Bolivia. It inhabits humid montane forests, cloud forests, forest edges, and scrub, at a broad range of elevations from 1,500 to 3,800 meters (4,900-12,500 feet).

Look for a small, dark hummingbird with a short, straight bill and a distinct metallic sheen on its tail (often red, coppery, or greenish). Males typically have an iridescent gorget (throat) that can vary in color (green, blue, violet). Observe them feeding at various levels, from low shrubs to mid-canopy flowers, and listen for their high-pitched calls.

Active year-round during daylight. Best observed in the mornings when nectar availability is high, or near flowering plants and feeders. They are generally reliable residents within their preferred habitats.
