The bronze-tailed thornbill (Chalcostigma heteropogon) is a species of hummingbird in the "coquettes", tribe Lesbiini of subfamily Lesbiinae. It is found in Colombia and Venezuela. The taxonomy of genus Chalcostigma is unsettled. The South American Classification Committee (SACC) of the American Ornithological Society is considering a proposal to merge the genus into Oxypogon. The bronze-tailed thornbill is monotypic.
The bronze-tailed thornbill is 13 to 14 cm (5.1 to 5.5 in) long and weighs 5.9 to 6.3 g (0.21 to 0.22 oz). Both sexes have a short straight black bill. Adults are generally bottle green overall, with coppery red uppertail coverts and a forked olive green tail. Adult males have a narrow gorget that is emerald green under the chin and transitions to pink at the bottom. Adult females are similar but the gorget is paler green and does not have the pink "beard"; in addition their outer tail feathers have pale tips. Juveniles resemble adult females with the addition of a mahogany red crown.

GBIF citizen-science records
It is estimated from how often the Bronze-tailed Thornbill is recorded against all the birds logged in Chingaza National Natural Park (423 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.
