Philadelphia Vireo

About This Species

A small, subtle vireo with yellowish underparts, the Philadelphia Vireo breeds in northern deciduous and mixed forests and is often confused with the similar Warbling Vireo.

Fun Facts

• Late migrants: They are among the latest warblers and vireos to arrive in spring, typically not appearing until mid-May.
• Song similarities: Their song is nearly identical to Red-eyed Vireo but slightly higher-pitched and slower.
• Elusive nature: Despite being relatively common, they are often overlooked due to their preference for high forest canopies.
• Breeding range: Nest primarily in aspen and willow habitats across Canada and the northern U.S.
