Coeligena torquata is a species of hummingbird distributed across the Andes of Colombia, Ecuador, northern Peru, and parts of Venezuela, primarily found in cloud forest environments at elevations ranging from approximately 5,250 to 11,150 feet. It inhabits the edges of humid montane forests, elfin forests, and shaded ravines, often frequenting areas with abundant flowering plants such as Fuchsia, Bomarea, and Palicourea. While it is mainly restricted to its native range, some localized movement to slightly lower elevations occurs seasonally.

This hummingbird species measures around 5.3 to 5.9 inches in length, including a long, straight bill adapted for feeding on tubular flowers. Males exhibit dark iridescent green plumage with violet-black wings, a distinctive white postocular spot, and a pronounced white chest band that gives the species its specific name. Females display a similar coloration pattern but with less contrast and a slightly duller throat and belly. The bird is known for defending feeding territories aggressively, often chasing away other hummingbirds from favored nectar sources. It supplements its diet with small arthropods captured through aerial hawking. Although it is not considered rare, Coeligena torquata is typically seen singly or in pairs rather than in flocks. The species is categorized as Least Concern by the IUCN.
