The bronze-tailed plumeleteer (Chalybura urochrysia) is a species of hummingbird in the "emeralds", tribe Trochilini of subfamily Trochilinae. It is found in Colombia, Costa Rica, Ecuador, Nicaragua, and Panama. The bronze-tailed plumeleteer was formally described and illustrated in 1861 by the English ornithologist John Gould based on a specimen that had been supplied by the Polish collector Józef Warszewicz. Gould coined the binomial name Hypuroptila urochrysia but mistakenly gave the locality as the "neighbourhood of Panama". The locality has been redesignated as western Columbia. The bronze-tailed plumeleteer is now placed with the white-vented plumeleteer in the genus Chalybura that was introduced in 1854 by Ludwig Reichenbach. The genus name combines the Ancient Greek χαλυψ/khalups, χαλυβος/khalubos meaning "steel" with ουρα/oura meaning "tail". The specific epithet combines the Ancient Greek ουρα/oura meaning "tail" with χρυσεος/khruseos meaning "golden".

GBIF citizen-science records
It is estimated from how often the Bronze-tailed Plumeleteer is recorded against all the birds logged in Arenal Volcano National Park (2,881 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.
