The scrub euphonia (Euphonia affinis) is a species of bird in the family Fringillidae, the finches and euphonias. It is found from Mexico to Costa Rica. The scrub euphonia was originally described in 1842 with the binomial Tanagra (Euphonia) affinis. Genus Tanagra was later subsumed into Euphonia. The genus Euphonia had long 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 scrub euphonia's further taxonomy is unsettled. In that year they recognized godmani as a full species, the West Mexican euphonia. However, as of late 2025, BirdLife International's Handbook of the Birds of the World (HBW) retains godmani as a subspecies of the scrub euphonia.
This article follows the two-subspecies model. The scrub euphonia is about 10 cm (3.9 in) long. It weighs 8.5 to 12.8... Wikipedia →

Possible
About 20% of wildlife watchers report a Scrub Euphonia sighting in Calakmul Biosphere Reserve on a given day, based on 155 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 73rd most-seen of the 271 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
March
In that month about 50% of wildlife watchers report a Scrub Euphonia in Calakmul Biosphere Reserve on a given day, against about 10% in February, June–August and November–December, the lowest months. That is one of Calakmul Biosphere Reserve's driest months, with about 20 mm of rain against 130 mm in June.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Scrub Euphonia sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
6th of 26
Of the 26 parks where we can rate Scrub Euphonia sightings, Calakmul Biosphere Reserve ranks 6th at about 20%. The best odds are in Masaya Volcano National Park (Nicaragua, about 60%), Santa Rosa National Park (Costa Rica, about 40%) and Pico Bonito National Park (Honduras, about 30%). All parks ranked.
Same genus: Euphonia
The closest relatives of the Scrub Euphonia that you can see in Calakmul Biosphere Reserve (genus Euphonia, Typical Euphonias) are Yellow-throated Euphonia (about 30%) and Olive-backed Euphonia (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Scrub Euphonia is recorded against all the birds logged in Calakmul Biosphere Reserve (155 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.
