Philadelphia Vireo

Vireo philadelphicus (Cassin, 1851)

Philadelphia Vireo, Vireo philadelphicus, is a passerine of the Vireonidae family that breeds across central and southern Canada and into the north-central and north-eastern United States, and spends the non-breeding season in Massachusetts and north-western South America. It was described by Cassin in 1851. It is a small North American songbird. The bird is best told from the warbling vireo by its much yellower underparts and dark lores. Its name links it with Philadelphia, though it is not tied to the city in its range.
