Trochilus polytmus (Streamertail; Red-billed Streamertail)

Wikipedia Abstract

The red-billed streamertail (Trochilus polytmus), also known as the doctor bird, scissor-tail or scissors tail hummingbird, is indigenous to Jamaica, where it is the most abundant and widespread member of the hummingbird family. While most authorities now consider it a separate species, some (including the American Ornithologists' Union) continue to consider it conspecific with the black-billed streamertail. The red-billed streamertail is the national bird of Jamaica. These birds feed on nectar from flowers using a long extendable tongue or catch small insects on the wing.
