The chestnut-sided warbler (Setophaga pensylvanica) is a New World warbler. They breed in eastern North America and in southern Canada westwards to the Canadian Prairies. They also breed in the Great Lakes region and in the eastern United States.
The chestnut-sided warbler was formally described in 1766 by the Swedish naturalist Carl Linnaeus in the twelfth edition of his Systema Naturae under the binomial name Motacilla pensylvanica. Linnaeus based his account on the "Red-throated fly-catcher" that had been described and illustrated in 1760 by the English naturalist George Edwards in his book Gleanings of Natural History. Edwards had received specimens from the American naturalist William Bartram that had been collected in Pennsylvania. The chestnut-sided warbler is now one of more than 30 species placed in the genus Setophaga that was introduced in 1827 by the English naturalist William Swainson. 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.
Setophaga icterocephala is a junior synonym of S. pennsylvanicus, and is no longer used. The... Wikipedia →

Rare
Under 5% of wildlife watchers report a Chestnut-sided Warbler sighting in Miami on a given day, based on 354 verified sightings from GBIF citizen-science data. It is the 172nd most-seen of the 325 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.
October
In that month about 10% of wildlife watchers report a Chestnut-sided Warbler in Miami on a given day, against under 5% in November to September, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Chestnut-sided 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.
19th of 30
Of the 30 cities where we can rate Chestnut-sided Warbler sightings, Miami ranks 19th at under 5%. The best odds are in Chicago (United States, about 10%), San José (Costa Rica, about 10%) and New York City (United States, about 10%).
Same genus: Setophaga
The closest relatives of the Chestnut-sided Warbler that you can see in Miami (genus Setophaga, Setophaga Warblers) are Palm Warbler (about 50%), Northern Parula (about 30%) and Yellow-rumped Warbler (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Chestnut-sided Warbler is recorded against all the birds logged in Miami (354 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.
