The rufous-breasted hermit or hairy hermit (Glaucis hirsutus) is a hummingbird that breeds from Panama south to Bolivia, and on Trinidad, Tobago and Grenada. It is a widespread and generally common species, though local populations may change in numbers and disappear altogether in marginal habitat.
The rufous-breasted hermit was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with all the other hummingbirds in the genus Trochilus and coined the binomial name Trochilus hirsutus. Gmelin's description was based on that of the German naturalist Georg Marcgrave in his Historia Naturalis Brasiliae that had been published 140 years earlier in 1648. The rufous-breasted hermit is now placed with two other species in the genus Glaucis that was introduced in 1831 by the German zoologist Friedrich Boie. The genus name is from the Ancient Greek glaukos meaning "blue-grey", "glaucous" or "pale green". The specific epithet hirsutus is Latin meaning "hairy" or "bristled". The type locality is northeast Brazil.

GBIF citizen-science records
It is estimated from how often the Rufous-breasted Hermit is recorded against all the birds logged in Belém (61 verified sightings), 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.
