Their central pair of tail feathers are green and the other four pairs whitish. Their underparts are glittering green with white undertail coverts. Females have green upperparts with a similar wing "patch" as the male's. Their central tail feathers are green and the others white with some dusky green. Voice: The Oaxaca hummingbird's song is "a high, rapid, warbling" described as similar to that of the white-tailed hummingbird but "jerkier, less hurried".
