Friday's Foto

The Philadelphia Vireo is a small songbird that can be seen passing through NYC during migration, although more frequently during their south-bound, Fall trip when the route is more easterly. Similar in coloration and size to the Warbling Vireo and Tennessee Warbler, the former has yellowish flanks, but not yellow on breast, and has less distinct facial pattern, the latter is slightly smaller, has thinner, more pointed bill, and a bright green back.

Nearly 90% of the world’s population breeds in the Canadian boreal forest. They winter in southern Mexico and Central America south to Panama.

The IUCN Red List lists their conservation status as “Least Concern” due to its extremely large range and increasing population trends.

The scientific name, Vireo philadelphicus, means "small green migratory bird" of "Philadelphia" (it was first described by John Cassin in 1842 from a specimen collected near Philadelphia).
