Hummingbirds (Trochilidae)

Bronzy Hermit (Glaucis aenea) - HBW 5, p. 538

French: Ermite bronzé German: Kupferschattenkolibri Spanish: Ermitaño Bronceado
Other common names: Bronze/Chestnut-colored Hermit

Taxonomy: Glaucis æneus Lawrence, 1867, Costa Rica.
Sister species of G. hirsuta, and these two often considered conspecific, but they meet in W Panama and W Colombia without interbreeding; present species probably had continuous distribution in past, but now interrupted by G. hirsuta, by which it is presumably being gradually replaced. Slight size and weight differences exist between the two discrete populations, Central American birds having longer wings than South American ones, but plumage coloration identical; South American populations sometimes separated as race columbiana. Monotypic.

Distribution: E Honduras, E Nicaragua and Costa Rica to W Panama; W Colombia to W Ecuador.
