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

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 Boston on a given day, based on 5,139 verified sightings from GBIF citizen-science data. It is the 50th most-seen of the 283 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
May
In that month about 40% of wildlife watchers report a Black-and-white Warbler in Boston on a given day, against under 5% in June–August and October–April, the lowest months.
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.
13th of 45
Of the 45 cities where we can rate Black-and-white Warbler sightings, Boston ranks 13th 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 Boston (family Parulidae, New World Warblers) are Yellow-rumped Warbler (about 20%), Yellow Warbler (about 20%) and Northern Yellow Warbler (about 10%), 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 Boston (5,139 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.
