This hummingbird inhabits humid Andean forests. A white chest band stands out against its dark plumage, and it feeds on nectar as well as small insects and spiders.
Its dark plumage has an iridescent green sheen, with a conspicuous white band across the chest and white on the tail.
It drinks nectar and also eats small insects and spiders. It may defend productive feeding areas from other hummingbirds.
