Glaucous gull

The glaucous gull (Larus hyperboreus) is a large gull, the second largest gull in the world which breeds in the Arctic regions of the Northern Hemisphere and the Atlantic coasts of Europe. It is migratory, wintering from in the North Atlantic and North Pacific oceans as far south as the British Isles and northernmost states of the USA, also on the Great Lakes. A few birds sometimes reach the southern USA and northern Mexico.
