The yellow-footed gull (''Larus livens'') is a large gull, closely related to the western gull and thought to be a subspecies until the 1960s. It is native to the Gulf of California. ==Description== Adults are similar in appearance to the western gull with a white head, dark, slate-colored back and wings, and a thick yellow bill. Its legs are yellow, though first winter birds do display pink legs like those of the western gull. It attains full plumage at three years of age. This species is one of the largest gulls in the world, being slightly larger than the already large western gull. It measures in length and spans across the wings.〔''Gulls: Of North America, Europe, and Asia'' by Klaus Malling Olsen & Hans Larsson. Princeton University Press (2004).
