The Red-billed Streamertail lives across most of Jamaica. The long tail streamers belong to males, and the island's far eastern tip is occupied by a separate species.
Adult males have a red bill, green head, and long black tail streamers. Females lack the streamers and have less prominent red-and-white patterning below.
It feeds on flower nectar as well as small insects and spiders.
