The yellow-throated vireo (Vireo flavifrons) is a small American songbird. The generic name Vireo is a Latin word referring to a green migratory bird, perhaps the female golden oriole, or possibly the European greenfinch. The specific name flavifrons is from the Latin words flavus, "yellow", and frons, "forehead".
Adults are mainly olive on the head and upperparts with a yellow throat and white belly; they have dark eyes with yellow "spectacles". The tail and wings are dark with white wing bars. They have thick blue-grey legs and a stout bill.
Measurements: Length: 5.1–5.9 in (13–15 cm) Weight: 0.5–0.7 oz (15–21 g) Wingspan: 9.1 in (23 cm) Their breeding habitat is open deciduous woods in southern Canada and the eastern United States. These birds migrate to the deep southern United States, Mexico, the Caribbean, and Central America.
They forage for insects high in trees... Wikipedia →

Possible
About 20% of wildlife watchers report a Yellow-throated Vireo sighting in Calakmul Biosphere Reserve on a given day, based on 188 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 56th 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 and October
In those months about 40% of wildlife watchers report a Yellow-throated Vireo in Calakmul Biosphere Reserve on a given day, against under 5% in June and July, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Yellow-throated Vireo sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 59
Of the 59 parks where we can rate Yellow-throated Vireo sightings, Calakmul Biosphere Reserve ranks 4th at about 20%. The best odds are in Santa Rosa National Park (Costa Rica, about 30%), Tikal National Park (Guatemala, about 30%) and Congaree National Park (United States, about 20%).
Same genus: Vireo
The closest relatives of the Yellow-throated Vireo that you can see in Calakmul Biosphere Reserve (genus Vireo, Vireos) are White-eyed Vireo (about 50%), Mangrove Vireo (about 10%) and Yellow-green Vireo (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Yellow-throated Vireo is recorded against all the birds logged in Calakmul Biosphere Reserve (188 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.
