The common yellowthroat (Geothlypis trichas) is a New World warbler. It is an abundant breeder in North America, ranging from southern Canada to central Mexico. In the northern parts of its range the birds are migratory, wintering in the southern parts of the breeding range, Central America and the West Indies. Southern forms are largely resident. Historically, it has also been known as the "yellow bandit", Maryland yellow-throat, and yellow-breasted warbler.
The common yellowthroat was formally described in 1766 by the Swedish naturalist Carl Linnaeus in the twelfth edition of his Systema Naturae under the binomial name Turdus trichas. The specific epithet is from Ancient Greek τριχας/trikhas, τριχαδος/trikhados, a type of thrush. Linnaeus based his account on "The Maryland yellow-throat" that had been described and illustrated in 1758 by the English naturalist George Edwards in his book Gleanings of Natural History. Linnaeus specified the locality as North America but this was restricted to the state of Maryland by the American Ornithologists' Union in 1931. The common yellowthroat is now one of 15 species placed in the genus Geothlypis that was introduced in 1847... Wikipedia →

Possible
About 20% of wildlife watchers report a Common Yellowthroat sighting in León on a given day, based on 20 verified sightings from GBIF citizen-science data. It is the 54th most-seen of the 124 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 80%, if each day is a fresh chance.
April
In that month about 40% of wildlife watchers report a Common Yellowthroat in León on a given day, against about 10% in February–March, May, September and November, the lowest months. That is one of León's driest months, with about 5 mm of rain against 170 mm in July. June has too few records to rate.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Common Yellowthroat sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 44
Of the 44 cities where we can rate Common Yellowthroat sightings, León ranks 3rd at about 20%. The best odds are in Los Angeles (United States, about 40%) and Tijuana (México, about 30%).
Same family: Parulidae
The closest relatives of the Common Yellowthroat that you can see in León (family Parulidae, New World Warblers) are Yellow-rumped Warbler (about 50%), Wilson's Warbler (about 30%) and Audubon's Warbler (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common Yellowthroat is recorded against all the birds logged in León (20 verified sightings), 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.
