A bird of young deciduous woods, the Philadelphia Vireo is the most northernly breeding species of vireo. It is often overlooked because its more common relative, the Red-eyed Vireo lives in the same areas and gets most of the attention.
Song a broken series of slurred notes. Each phrase usually ends in either a downslur or an upswing, as if the bird asks a question, then answers it, over and over. May repeat same phrase twice or more in a row.
