Summary ²

The slaty-backed gull (Larus schistisagus) is a large white-headed gull that breeds on the western coast of Alaska but travels widely during nonbreeding seasons. It is similar in appearance to the western gull and the glaucous-winged gull. Another alternate name is Pacific gull, though this also applies to a southern hemisphere species, Larus pacificus. Claims have been made as to its (sometimes occasional) presence throughout North America as well as the eastern coast
