The purple-chested hummingbird (Polyerata rosenbergi) is a species of hummingbird in the family Trochilidae. It is found in Colombia and Ecuador. Its natural habitats are subtropical or tropical moist lowland forest and heavily degraded former forest. It is commonly hunted for the supposed medicinal properties of its beak by indigenous peoples in the area.
This species 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 purple-chested hummingbird was moved to the resurrected genus Polyerata. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Purple-chested Hummingbird is recorded against all the birds logged in Utría National Natural Park (11 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.
