The Blackburnian warbler (Setophaga fusca) is a small New World warbler. They breed in eastern North America, from southern Canada, westwards to the southern Canadian Prairies, the Great Lakes region and New England, to North Carolina. They are migratory, wintering in southern Central America and South America, and are very rare vagrants to western Europe. The common name honors the English botanist Anna Blackburne.
The Blackburnian warbler was formally described in 1776 by the German zoologist Philipp Statius Müller under the binomial name Motacilla fusca. The specific epithet is Latin meaning "dusky", "black" or "brown". Müller based his account on a handcoloured plate of the "Figuier étranger" that had been engraved by François-Nicolas Martinet to accompany the Comte de Buffon's multivolume work Histoire Naturelle des Oiseaux. The type location is French Guiana. The Blackburnian warbler is now placed in the genus Setophaga that was introduced by the English naturalist William Swainson in 1827. The genus name Setophaga combines the Ancient Greek σης/sēs, σητος/sētos meaning "moth" with -φαγος/-phagos meaning "-eating". The species is monotypic: no subspecies are recognised... Wikipedia →

Rare
Under 5% of wildlife watchers report a Blackburnian Warbler sighting in Arrecifes de Cozumel National Park on a given day, based on 19 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 173rd most-seen of the 205 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
September and October
In those months about 10% of wildlife watchers report a Blackburnian Warbler in Arrecifes de Cozumel National Park on a given day, against under 5% in November to August, the lowest months. Those are among Arrecifes de Cozumel National Park's wettest months, with about 180 mm of rain a month against 30 mm in March.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Blackburnian 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.
46th of 55
Of the 55 parks where we can rate Blackburnian Warbler sightings, Arrecifes de Cozumel National Park ranks 46th at under 5%. The best odds are in Farallones de Cali National Natural Park (Colombia, about 50%), Point Pelee National Park (Canada, about 40%) and Riding Mountain National Park (Canada, about 30%). All parks ranked.

The closest relatives of the Blackburnian Warbler that you can see in Arrecifes de Cozumel National Park (genus Setophaga, Setophaga Warblers) are Yellow Warbler (about 80%), American Redstart (about 60%) and Palm Warbler (about 50%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Blackburnian Warbler is recorded against all the birds logged in Arrecifes de Cozumel National Park (19 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.
