The coppery-headed emerald (Microchera cupreiceps) is a small hummingbird in the "emeralds", tribe Trochilini of subfamily Trochilinae. It is endemic to Costa Rica. The coppery-headed emerald was formerly placed with the white-tailed emerald (M. chionura) in the genus Elvira. A molecular phylogenetic study published in 2014 found that these two species were closely related to the snowcap in the then-monospecific genus Microchera. The International Ornithological Committee and the Clements taxonomy placed the three species together in Microchera which has priority. However, BirdLife International's Handbook of the Birds of the World retains them in Elvira.
The coppery-tailed emerald is monotypic. The coppery-headed emerald is about 7.5 cm (3.0 in) long and weighs about 3.0 to 3.3 g (0.11 to 0.12 oz). Both sexes have a moderately decurved bill whose mandible has a pinkish base. The adult male has a dull coppery bronze crown, a bronze green nape, back, and rump, and bright coppery bronze uppertail coverts. Its central pair of tail feathers are bronze, the next three pairs white with pale gray tips, and the outermost pair white with black... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Coppery-headed Emerald is recorded against all the birds logged in Poás Volcano National Park (1,772 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
