The Central American birds differ in voice and behaviour from those in South America and may be a separate species, the blue-vented hummingbird (A. hoffmanni). Both forms are sometimes placed in the genus Saucerottia, but this is not recognized by most authorities, notably AOU and Howard & Moore. This hummingbird inhabits open woodland such as second growth, coffee plantations, gardens, savanna, and the edges and gaps of evergreen forests. It occurs from sea level up to {{Convert|1800|m|ft|abbr = on}}. The nest is a cup of plant down and cobwebs, decorated outside with lichen and placed on a small outside twig {{Convert|2|-|7|m|ft|abbr=on}} high in a small tree. The female alone incubates the two white eggs. The steely-vented hummingbird is {{Convert|9|cm|in|abbr = on}} long and weighs {{Convert|4.5|g|oz|abbr = on}}. It is mainly bronze-green above, becoming more bronze on the wing, lower back and rump, and has a blue-black tail. The male has glittering green underparts, white thighs and a blue vent. The female is duller green below and has grey-buff edges to the vent feathers. Young birds are dull dark bronze-green below. The steely-vented hummingbird has a trilled descending chit call in South America, but the Blue-vented from Central America has a high sharp tsip. The male's song in Costa Rica is a buzzy bzz WEEP wup. This hummingbird feeds at many types of flowers, including epiphytes and Heliconias, and both sexes are aggressive and territorial, defending favoured areas.
