The straight-billed hermit (Phaethornis bourcieri) is a species of bird in the family Trochilidae, the hummingbirds. It is found in Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela. The straight-billed hermit and needle-billed hermit (P. philippii) were at one time placed in genus Ametrornis that was later merged into Phaethornis.
The straight-billed hermit is 12 to 14 cm (4.7 to 5.5 in) long and weighs 3.5 to 5 g (0.12 to 0.18 oz). It is one of the few hermit hummingbirds with a straight bill. Its upperparts are olive green and the underparts brownish to grayish. The... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Straight-billed Hermit is recorded against all the birds logged in Cuyabeno Wildlife Reserve (7 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.
