The white-vented plumeleteer (Chalybura buffonii) is a species of hummingbird in the "emeralds", tribe Trochilini of subfamily Trochilinae. It is found in Colombia, Ecuador, Panama, Peru, and Venezuela. Most taxonomic systems assign five subspecies to the white-vented plumeleteer:
However, BirdLife International's Handbook of the Birds of the World (HBW) assigns C. b. intermedia as a subspecies of bronze-tailed plumeleteer (C. urochrysia). The white-vented plumeleteer is 10.5 to 12 cm (4.1 to 4.7 in) long. Males weigh 6 to 7.3 g (0.21 to 0.26 oz) and females 5.9 to 7.9 g (0.21 to 0.28 oz). All of the subspecies except intermedia have a black bill and black feet; that one has a pinkish base to the mandible and pale pink to red feet.
Males of the nominate subspecies C. b. buffonii have mostly dark metallic green upperparts with a bronzy tinge to the crown... Wikipedia →

GBIF citizen-science records
It is estimated from how often the White-vented Plumeleteer is recorded against all the birds logged in Darién National Park (30 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.
