Honduran emerald

The Honduran emerald (Amazilia luciae) is a vulnerable species of hummingbird in the "emeralds" tribe, Trochilini, of the subfamily Trochilinae. It is endemic to Honduras.

The Honduran emerald is 9 to 10 cm (3.5 to 3.9 in) long. Both sexes have a medium length bill, slightly decurved, with a black maxilla and a red mandible with a black tip. Adult males have a dark green crown and upperparts that become bronzy on the lower back and uppertail coverts. Its central tail feathers are dark green, the rest dark green with a bronzy cast near the end, and all have a purplish band near the tip. Its gorget and upper breast are medium blue that may appear greenish or grayish in different lights. Its breast is grayish white with green sides and duller bronze green flanks. Its undertail coverts are dark green with white edges. The adult female has similar plumage but is overall duller. Its gorget is smaller and greener than the male's and its outer tail feathers have gray tips. Immature birds are similar to the female.

The call is "a hard, slightly metallic ticking call, often steadily repeated 'chik, chik-chik, chik chik..." and "a hard, slightly buzzy chattering given in flight 'zzchi ---' and 'chik chi zzhi ---'." Other vocalizations include "a dry, quiet gruff warbling" (which might be its song), "a hard buzzy chatter 'chirr-rr-irr-rr-rr'", and "a high sharp 'siik' given in pursuit."
