The blue-chested hummingbird (Polyerata amabilis) is a species of hummingbird in the family Trochilidae. It is found in Colombia, Costa Rica, Ecuador, Nicaragua, and Panama. Its natural habitats are subtropical or tropical moist lowland forest and heavily degraded former forest.
The hummingbird feeds by trap-lining and also defends feeding territory (particularly in nectar-poor habitat), taking nectar and also small insects gleaned from foliage. These foraging territories are often on the borders of forests in areas of scattered flowers. The males will form leks to try to gain the attention of females during breeding season.
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 blue-chested hummingbird was moved to the resurrected genus Polyerata. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Blue-chested Hummingbird is recorded against all the birds logged in Bastimentos Island National Marine Park (886 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.
