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 →

Likely
About 50% of wildlife watchers report a Blackburnian Warbler sighting in Farallones de Cali National Natural Park on a given day, based on 1,949 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 29th most-seen of the 542 birds we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
February–March and October–December
In those months about 70% of wildlife watchers report a Blackburnian Warbler in Farallones de Cali National Natural Park on a given day, against under 5% in May to August, the lowest months.
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.
Yes
Of the 55 parks where we can rate Blackburnian Warbler sightings, Farallones de Cali National Natural Park has the highest daily chance: about 50%. Next come Point Pelee National Park (Canada, about 40%) and Riding Mountain National Park (Canada, about 30%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Blackburnian Warbler is recorded against all the birds logged in Farallones de Cali National Natural Park (1,949 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.
