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 →

Rare
Under 5% of wildlife watchers report a Thick-billed Euphonia sighting in Darién National Park on a given day, based on 20 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 246th most-seen of the 397 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
August
In that month about 20% of wildlife watchers report a Thick-billed Euphonia in Darién National Park on a given day, against under 5% in March–May, July and September–January, the lowest months. That is one of Darién National Park's wettest months, with about 440 mm of rain against 100 mm in February.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Thick-billed Euphonia sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
21st of 28
Of the 28 parks where we can rate Thick-billed Euphonia sightings, Darién National Park ranks 21st at under 5%. The best odds are in Chagres National Park (Panama, about 60%), Machalilla National Park (Ecuador, about 30%) and Tayrona National Natural Park (Colombia, about 30%). All parks ranked.
Same genus: Euphonia
The closest relatives of the Thick-billed Euphonia that you can see in Darién National Park (genus Euphonia, Typical Euphonias) are Fulvous-vented Euphonia (about 20%) and Orange-bellied Euphonia (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Thick-billed Euphonia is recorded against all the birds logged in Darién National Park (20 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.
