The glaucous gull (Larus hyperboreus<\/em>) has a circumpolar, high-Arctic distribution and breeds throughout Svalbard. It is a generalist that exploits many different kinds of prey such as fish, molluscs, sea urchins, crustaceans, eggs, chicks and adults of other seabirds, as well as insects, carcasses and rubbish. The glaucous gull’s position uppermost in the food chain makes it susceptible to pollutants, and the species is listed as Vulnerable <\/em>(VU) in the 2021 Norwegian Red List due to small population size and ongoing decline.<\/p>\n\n\n\n
