The black-and-white warbler (Mniotilta varia) is a species of New World warbler, and the only member of its genus, Mniotilta.

It has been recorded as a vagrant in Northern Europe, especially Britain and Ireland. Relative to other New World warblers, it is not well studied.
The black-and-white warbler was formally described in 1766 by the Swedish naturalist Carl Linnaeus in the twelfth edition of his Systema Naturae under the binomial name Motacilla varia. The specific epithet is from Latin varius meaning "various", "diverse" or "variegated". Linnaeus based his entry of the "small black and white bird" that had been described by the Irish physician Hans Sloane in 1725 and "Le Figuier varié de S. Domingue" that had been described by the French ornithologist Louis Vieillot in 1760. Linnaeus specified the location as Jamaica and Dominica but this was restricted to Santo Domingo in the Dominican Republic by the American Ornithologists' Union in 1910. The black-and-white warbler is now the only species placed in the genus Mniotilta that was introduced by... Wikipedia →

With luck
About 10% of wildlife watchers report a Black-and-white Warbler sighting in Chicago on a given day, based on 7,665 verified sightings from GBIF citizen-science data. It is the 62nd most-seen of the 314 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
May
In that month about 40% of wildlife watchers report a Black-and-white Warbler in Chicago on a given day, against under 5% in June–July and October–April, the lowest months. That is one of Chicago's wettest months, with about 120 mm of rain against 50 mm in January.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Black-and-white Warbler sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
12th of 45
Of the 45 cities where we can rate Black-and-white Warbler sightings, Chicago ranks 12th at about 10%. The best odds are in Havana (Cuba, about 30%), Miami (United States, about 30%) and Santo Domingo (Dominican Republic, about 30%).
Same family: Parulidae
The closest relatives of the Black-and-white Warbler that you can see in Chicago (family Parulidae, New World Warblers) are Yellow-rumped Warbler (about 30%), Common Yellowthroat (about 20%) and American Redstart (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Black-and-white Warbler is recorded against all the birds logged in Chicago (7,665 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.
