The Yellow-rumped Warbler is one of the most common warblers in North America. This is the eastern form; the western form has a yellow throat. You can’t see it in this photo, but it does have a yellow rump, which is a good field mark for identification. Yellow-rumps are able to digest a more varied diet than other warblers. For example, they can digest the wax coating on bayberries. Because of this, they can winter much farther north than other warblers can, living on fruit. Many of them stay in the United States during the winter and some are even found as far north as Nova Scotia. Some do migrate to Mexico and the Caribbean. During the summer, Yellow-rumps nest all across Canada, in the northeastern United States, and in most of the western states.
