Rufous-vented Whitetips inhabit the understory of humid montane forests, especially in semi-open areas. They forage at low or mid levels of the forest on nectar and insects and sometimes migrate to higher elevations after the breeding season. These medium-sized hummingbirds are green above and have a white spot behind the eye. Males have a large white spot on their forked tails, formed by the white lower halves of the central tail feathers. Females’ tails are bronzy green with white tips.
