Nearly identical to Blue-chested Hummingbird but no range overlap. Male has glittering purple-blue throat, green back and crown, paler grayish belly, and dark tail. Female less obvious, with spotted chest; note the pink base to the lower mandible of the bill. She is smaller than most other female hummingbirds that have spotted chests, such as White-necked Jacobin. Usually seen fairly low at a forest edge or shrubby second growth.
