Pine Warbler

True to its name, this warbler is largely restricted to pine and mixed pine-hardwood forests across the eastern United States, where it forages by creeping along branches and trunks more like a vireo than a typical warbler. Its song is a musical, even-pitched trill, similar to a chipping sparrow's but slower and richer, and is one of the earliest warbler songs heard in spring in the southeast. It also visits feeders in winter for suet and sunflower seed where resident populations occur, making cold months an easier time to see one at close range.
