The Yellow-rumped Warbler is an exceptionally widespread bird. It is highly migratory and in the summer can be found as far north as the artic tundra of Alaska and Canada and in the winter as far south as the jungles of Panama. At some point in the year or another, it can be found in every single country in North America including every state or province of Canada, Mexico, and the US (not including Hawaii). Most warblers are more difficult to identify than it given that many are just variations of a small yellow bird, but the Yellow-rumped Warbler has a much more distinctive appearance which makes it easy to identify. It’s same comes from a bright yellow patch just above its tail, but this photo shows several other yellow patches on the sides of the chest and the top of the head.
