Copper-tailed Hummingbird

The copper-tailed hummingbird (Saucerottia cupreicauda) is a species of hummingbird in the "emeralds", tribe Trochilini of subfamily Trochilinae. It is native to the tepuis of Venezuela and nearby areas of Brazil and Guyana; it is a vagrant in French Guiana. == Taxonomy and systematics == The copper-tailed hummingbird was formally described in 1884 by the English naturalists Osbert Salvin and Frederick DuCane Godman based on specimens collected by Henry Whitely near Mount Roraima in Guyana. Salvin and Godman placed the new species in the genus Amazilia and coined the binomial name Amazilia cupreicauda. The specific epithet combines the Latin cupreus meaning "coppery" with cauda meaning "tail". A molecular phylogenetic study published in 2014 found that the genus Amazilia was polyphyletic. In the revised classification to create monophyletic genera, the copper-tailed hummingbird was moved by most taxonomic systems to the resurrected genus Saucerottia. The copper-tailed hummingbird's four subspecies were previously considered subspecies of the green-bellied hummingbird (S. viridigaster). By early 2023 most taxonomic systems had created the copper-tailed hummingbird (S. cupreicauda) containing four of them. However, the South American Classification Committee of the American Ornithological Society does not recognize the copper-tailed hummingbird as a separate species. The four subspecies are: Saucerottia…
