The yellow-throated euphonia (Euphonia hirundinacea) is a species of songbird in the family Fringillidae. It is found in southeastern Mexico and throughout Central America with its range stretching from Belize south to western Panama. It inhabits primarily both humid and dry regions where it prefers the forest edge, open woodland, and shaded plantations. It has two subspecies, the nominate subspecies Euphonia hirundinacea hirundinacea and Euphonia hirundinacea gnatho. This finch is a small bird with pointed wings and a short bill and short tail. Males of this species have dark glossy blue-black upperparts excluding a yellow forecrown, and bright yellow underparts, while females have olive green upperparts and whitish-gray breast and lower parts. It has a shrill song that alternates between high-pitched and moderately pitched and appears to be able to mimic some calls of other birds.
The yellow-throated euphonia is a frugivore that feeds primarily on mistletoe berries, which it swallows whole, and has also been observed feeding on figs and ripe bananas. Breeding dates range from March to August depending on locality. Breeding pairs work together to build a domed nest and visit the nest in pairs to feed hatchlings. It is listed as a species of least concern due to its stable population and large range. Wikipedia →

Possible
About 30% of wildlife watchers report a Yellow-throated Euphonia sighting in Calakmul Biosphere Reserve on a given day, based on 282 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 37th most-seen of the 271 birds we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
January
In that month about 50% of wildlife watchers report a Yellow-throated Euphonia in Calakmul Biosphere Reserve on a given day, against about 20% in May–June and October–December, the lowest months. That is one of Calakmul Biosphere Reserve's driest months, with about 30 mm of rain against 130 mm in June.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Yellow-throated 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.
9th of 30
Of the 30 parks where we can rate Yellow-throated Euphonia sightings, Calakmul Biosphere Reserve ranks 9th at about 30%. The best odds are in Tenorio Volcano National Park (Costa Rica, about 60%), Cerro Azul Meámbar National Park (Honduras, about 50%) and Sian Ka'an Biosphere Reserve (Mexico, about 50%). All parks ranked.
Same genus: Euphonia
The closest relatives of the Yellow-throated Euphonia that you can see in Calakmul Biosphere Reserve (genus Euphonia, Typical Euphonias) are Scrub Euphonia (about 20%) 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 Yellow-throated Euphonia is recorded against all the birds logged in Calakmul Biosphere Reserve (282 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.
