The rufous-bellied euphonia (Euphonia rufiventris) is a species of bird in the family Fringillidae, the finches and euphonias. It is found in Bolivia, Brazil, Colombia, Ecuador, Peru, and Venezuela. The rufous-bellied euphonia was formally described in 1819 with the binomial Tanagra rufiventris. The species was eventually reassigned to genus Euphonia. At the time, the genus Euphonia was a member of the family Thraupidae, the "true" tanagers. Multiple studies in the late twentieth and early twenty-first centuries resulted in Euphonia being reassigned to its present place in the family Fringillidae.
The rufous-bellied euphonia's further taxonomy is unsettled. This article follows the two-subspecies model. The rufous-bellied euphonia is about 10 cm (3.9 in) long and weighs 13 to 18 g (0.46 to 0.63 oz). It is a smallish euphonia... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Rufous-bellied Euphonia is recorded against all the birds logged in Tambopata National Reserve (163 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.
