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 Soberanía National Park on a given day, based on 444 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 238th most-seen of the 449 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
October
In that month about 20% of wildlife watchers report a Blackburnian Warbler in Soberanía National Park on a given day, against under 5% in May–August and November–March, the lowest months. That is one of Soberanía National Park's wettest months, with about 330 mm of rain against 25 mm in February.
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.
29th of 55
Of the 55 parks where we can rate Blackburnian Warbler sightings, Soberanía National Park ranks 29th 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.
Same genus: Setophaga
The closest relatives of the Blackburnian Warbler that you can see in Soberanía National Park (genus Setophaga, Setophaga Warblers) are Bay-breasted Warbler (about 30%), Yellow Warbler (about 30%) and Chestnut-sided Warbler (about 20%), 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 Soberanía National Park (444 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.
