Fairly small hummingbird with limited range near the coast from extreme southeast Panama to northwest Ecuador. Males are distinctive: mostly green with a bluish crown and throat, white undertail coverts, and a white stripe up the belly. Note bright red bill with a black tip. Females have dingy whitish underparts with some green spotting on the neck and flanks; look for reddish bill base. Occurs in scrubby second growth and mangroves in coastal lowlands, most often seen around a flowering tree or shrub.
