The stripe-tailed hummingbird (Eupherusa eximia) is a species of hummingbird in the "emeralds", tribe Trochilini of subfamily Trochilinae. It is found from southeastern Mexico to Panama. Some authors have also treated the white-tailed hummingbird (E. poliocerca) and Oaxaca hummingbird (E. cyanophrys) as additional subspecies.
The stripe-tailed hummingbird is 9 to 10.5 cm (3.5 to 4.1 in) long and weighs an average of 4–4.5 g (0.14–0.16 oz). Both sexes of all subspecies have a straight black bill. The nominate male has bright metallic grass green upperparts that is more bronzy on the uppertail coverts. Cinnamon rufous secondaries show as a patch on the folded wing. Its three inner pairs of tail feathers are dark bronze green; the outer two pairs have black outer webs and white inner ones with black tips, giving the species its English name. Its underparts are bright metallic grass green with white undertail coverts. The female also has grass green upperparts; its underparts are brownish gray with metallic green spots on the sides...
