The Cape May warbler (Setophaga tigrina) is a species of New World warbler. It breeds in northern North America. Its breeding range spans all but the westernmost parts of southern Canada, the Great Lakes region, and New England. It is migratory, wintering in the West Indies. This species is a very rare vagrant to western Europe, with two records in Britain as of October 2013. The English name refers to Cape May, New Jersey, where George Ord collected the specimen that was later described by Alexander Wilson.
The Cape May warbler was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it in the genus Motacilla and coined the binomial name Motacilla tigrina. The specific epithet is from Latin tigrinus meaning "tigrine" or "barred or striped like a tiger". Gmelin based his account on "The yellow spotted fly-catcher" that had been described by the English naturalist George Edwards in 1758, and "Le figuier brun de Canada" that had been described by French zoologist Mathurin Jacques Brisson in 1760. The Cape May warbler is now one of more than 30 species placed in the genus... Wikipedia →

Rare
Under 5% of wildlife watchers report a Cape May Warbler sighting in Philadelphia on a given day, based on 709 verified sightings from GBIF citizen-science data. It is the 108th most-seen of the 248 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
May and September–October
In those months about 10% of wildlife watchers report a Cape May Warbler in Philadelphia on a given day, against under 5% in June–August and November–April, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Cape May Warbler sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
14th of 25
Of the 25 cities where we can rate Cape May Warbler sightings, Philadelphia ranks 14th at under 5%. The best odds are in Santo Domingo (Dominican Republic, about 30%), Managua (Nicaragua, about 10%) and Miami (United States, about 10%).
Same genus: Setophaga
The closest relatives of the Cape May Warbler that you can see in Philadelphia (genus Setophaga, Setophaga Warblers) are Yellow-rumped Warbler (about 20%), American Redstart (about 10%) 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 Cape May Warbler is recorded against all the birds logged in Philadelphia (709 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.
