The white-eared hummingbird (Basilinna leucotis) is a species of hummingbird in the "emeralds", tribe Trochilini of subfamily Trochilinae. It is found from the southwestern U.S. to Nicaragua. The white-eared hummingbird was originally placed in genus Trochilus and then moved to Hylocharis. A study published in 2014 determined that both were in error and it was moved to Basilinna.
The white-eared hummingbird is 9 to 10 cm (3.5 to 3.9 in) long. Males weigh an average of 3.6 g (0.13 oz) and females 3.2 g (0.11 oz). Adults of the three subspecies are very similar.

Their upperparts are bright metallic green to bronze green and the uppertail coverts more bronzy; the rump and covert feathers have rusty edges. The central pair of tail feathers... Wikipedia →
