The golden-tailed sapphire (Chrysuronia oenone) is a species of hummingbird in the family Trochilidae. It is found in Bolivia, Brazil, Colombia, Ecuador, Peru, and Venezuela. The golden-tailed sapphire was formerly placed in the genus Amazilia. A molecular phylogenetic study published in 2014 found that Amazilia was polyphyletic. In the revised classification to create monophyletic genera, the golden-tailed sapphire was moved by most taxonomic systems to Chrysuronia. However, BirdLife International's Handbook of the Birds of the World (HBW) retains it in Amazilia.
The Clements taxonomy and HBW add a third, C. o. alleni, that the IOC includes within josephinae. The golden-tailed sapphire is 9.5 to 10 cm (3.7 to 3.9 in) long. Males weigh 4.7 to 6.3 g (0.17 to 0.22 oz) and females 4.3 to 5.3 g (0.15 to 0.19 oz). Both sexes of all subspecies have a slightly curved bill with a black maxilla and a black-tipped red mandible.
Adult males of the nominate subspecies have a violet-blue head and throat... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Golden-tailed Sapphire is recorded against all the birds logged in Amboró National Park (51 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.
