About the Chestnut-sided Warbler

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 →
