Sabine's Gull (Larus sabini) (Xema sabini)
Sabine's Gull are not the easiest bird to find, even leading tours in Nome, AK. I have seen more on the coast of CA than in AK. A number of Sabie's Gulls take an unusual route south during fall migration. They do not follow the ocean, but they do take a route down through the Great Basin Desert. I have seen a few of these birds over Manzanita Lake in Lassen National Park.
