A large, aggressive hummingbird that usually dominates feeders or flower patches. Sparkling green overall with purplish-blue patches on cheeks and belly. Sexes alike. Larger than Lesser Violetear, and that species lacks the purple belly. Widespread in the Andes. Uses open habitats, including forest edge, shrubby agricultural land, and towns and cities. Found from 400–4,500 m; most common from the subtropical zone up to high elevation scrub and dry valleys, but also wanders low into foothills. Listen for the incessant song, a never-ending series of metallic chip notes.
