Yellow-billed Loon (Gavia adamsii)
is a big of the far north that winters along the Pacific coast of Alaska and Canada. In recent years solitary birds have been sen at inland lakes in the Lower 48 states. In Arizona there have been a couple of birds seen on the Colorado River near Lake Havasau.
This bird was a remarkable find on Tempe Town Lake in the Phoenix metro area where it stayed for a few days. Photographed May 23, 2008.
