The thick-billed euphonia (Euphonia laniirostris) is a species of bird in the family Fringillidae, the finches and euphonias. It is found in Bolivia, Brazil, Colombia, Costa Rica, Ecuador, Panama, Peru, and Venezuela. The thick-billed euphonia was originally described in 1837 with its current binomial Euphonia laniirostris (though spelled as "E. lanii rostris"). The genus Euphonia had long been placed in the family Thraupidae, the "true" tanagers. Multiple studies in the late twentieth and early twenty-first centuries resulted in its being reassigned to its present place in the family Fringillidae.
The thick-billed euphonia has these five subspecies: Subspecies E. l. melanura was originally described as a full species. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Thick-billed Euphonia is recorded against all the birds logged in San Lorenzo Protected Forest (64 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.
