Habitat: forest, gardens, parks, plantations, riverine area, secondary forest, and woodlands.
Range: Eastern Jamaica.
Note: Like its cousin, the red-billed streamertail, it is also endemic to Jamaica. Jamaicans dub them the "doctor birds." Peculiarly, in flight their long, black tail feathers trail them with a drone. The streamers add about 6–7 inches to the bird's overall length. Otherwise, its length is about 3.25–3.5 inches (see the red-billed streamertail hummingbird, below.)
