1. Larus leucopterus ( = Iceland Gull (Larus leucopterus))

The Iceland gull (Larus glaucoides) is a medium-sized gull that breeds in the Arctic regions of Canada and Greenland, but not in Iceland (as its name suggests), where it is only seen during winter. The genus name is from Latin larus, which appears to have referred to a gull or other large seabird. The specific name glaucoides denotes its resemblance to Larus glaucus, a synonym of Larus hyperboreus, the glaucous gull; -oides is Ancient Greek and means "resembling".


2. Larus glaucus ( = Glaucous Gull (Larus hyperboreus))

The glaucous gull (Larus hyperboreus) is a large gull, the second-largest gull in the world. It breeds in Arctic regions of the Northern Hemisphere and winters south to shores of the Holarctic. The glaucous gulls breed colonially or singly on coasts and cliffs, making a lined nest on the ground or cliff. Normally, two to four light brown eggs with dark brown splotches are laid. These gulls are omnivores like most Larus gulls, and they eat fish, insects, molluscs, starfish, offal, scraps, eggs, small birds, small mammals, and carrion, as well as seeds, berries, and grains.
