BRI and the Yellow-billed Loon

The largest of loons, it nests in a relatively small part of the arctic. It has basically the same breeding and wintering coloring as the Common Loon except for a yellow bill. In the winter it tends to have more white on the face than the Common Loon. It breeds in the Arctic, Russia, Canada, and Alaska. In the winter it can be found off the coasts of Norway and western Canada. Sometimes they go to large inland lakes and have been as far south as Arizona.
