About the Northern Yellow Warbler

The American yellow warbler (Setophaga aestiva), also known as the northern yellow warbler, is a New World warbler. It is a widespread migratory species in the diverse genus Setophaga, that breeds in most parts of North America. It was formerly considered to be conspecific with the non-migratory mangrove warbler (Setophaga petechia).

The American yellow warbler was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He mainly based his account on a hand-coloured engraving of the "Figuier de Canada" by François-Nicolas Martinet. Gmelin placed the warbler in the genus Motacilla and coined the binomial name Motacilla aestiva. In 1957 the type locality was restricted to Quebec in Canada. The specific epithet aestiva is from Latin aestivus meaning "summery", from aestas, aestatis meaning "summer". The American yellow warbler is now one of the 35 species in the genus Setophaga. The genus name Setophaga combines the Ancient Greek σης/sēs, σητος/sētos meaning "moth" with -φαγος/-phagos meaning "-eating".
