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 Yasuní National Park (638 verified sightings from 2019 to 2026), calibrated against known sighting rates.
