Mountain Velvetbreasts are best identified by their thin, decurved bills and their whitish tale patches. These hummingbirds are most often seen hovering over long tubular flowers, frequently fanning out their tails as they do so. While males defend feeding territories, females tend to forage at scattered flowers. Both sexes are often decorated with pollen all over their crowns from foraging. Mountain Velvetbreasts inhabit humid and wet montane forests—especially around the borders. They also like streams and shrubby slopes.
