The Pine Warbler is one of the few warblers that make appearances at bird feeders. They live year round in pine forests of the southeast U.S. and several Caribbean islands. Early spring is a good time to see them migrating through cities in the Midwest and the East Coast. If there’s a pine or two nearby, look for them picking through pine needles for food. Their song, heard throughout the year, is a sweet-sounding trill. Learn more at BirdNote.org.
