Although most people think of gulls collectively as “seagulls”, there are many distinct gull species worldwide. The glaucous-winged gull is a large gull who possesses a red spot on the underside of their yellow bill, pink-purple legs, and the standard gull uniform of pale gray and white. The gray wingtips help differentiate them from the herring and the Thayer’s gulls both of whom have black wingtips.
Like many other gulls, the glaucous-winged gull is an opportunist. Besides subsisting on carrion and refuse, these gulls will occasionally kill and eat small rodents, birds, and even the young of other gulls.
