The Stripe-tailed Hummingbird’s most distinctive feature is probably its rufous wing patch. These hummingbirds inhabit cool, wet forest where they spend most of their time in the canopy. When away from the forest interior, they also drop to lower levels of the forest and females are sometimes seen in very shaded parts of the forest understory. Males are aggressive and defend flowers at times. They fan out their striped-looking tailed when singing.
