Wikipedia Abstract

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. The genus name is from Latin Larus which appears to have referred to a gull or other large seabird. The specific hyperboreus is Latin for "northern" from the Ancient Greek Huperboreoi people from the far north "Glaucous" is from Latin glaucus and denotes a bluish-green or grey colour.
