Key Field Marks

  • Medium-sized hummingbird, similar in both sexes, with an overall metallic green body and a paler, grayish-white lower belly.
  • Bill is fairly straight and mostly red or coral-pink with a contrasting black tip, a useful feature at rest or in flight.
  • Tail is distinctly rufous to reddish-brown, standing out clearly against the green body, especially when fanned or in flight — the source of the species' name.
  • Sexes look alike, unlike many hummingbirds, making plumage-based sex identification difficult in the field.

Separating It From Similar Species

  • Buff-bellied Hummingbird, found mainly in southern Texas and eastern Mexico, is very similar but shows a buffier, warmer-toned belly rather than the grayer belly of Rufous-tailed Hummingbird, and the two have largely separate ranges with limited overlap.
  • Chestnut-bellied Hummingbird has a darker, richer chestnut belly rather than the paler gray-white underparts of Rufous-tailed Hummingbird.
  • The bicolored red-and-black bill together with the rufous tail is a reliable combination for separating this species from most other similarly sized green hummingbirds sharing its range.

Where and When to Look

  • Widespread and common resident from Mexico through Central America and into northern South America (Colombia, Venezuela, Ecuador).
  • Highly adaptable, found in forest edges, gardens, parks, plantations, and other human-altered and second-growth habitats, often more common in disturbed or open areas than in deep forest.
  • Present year-round with no long-distance migration; easily found at flowering shrubs and hummingbird feeders throughout its range.

Voice and Behavior

  • Vocalizations include scratchy, chattering calls and buzzy notes, frequently given while chasing other hummingbirds.
  • Notably aggressive and territorial, often dominating feeders and flowering patches against other hummingbird species.
  • Feeds on nectar from a wide variety of flowers as well as small insects caught in flight or gleaned from foliage.
