Iceland Gull (Larus glaucoides)
Despite its vernacular name, the Iceland Gull does not breed in Iceland but in Arctic Canada and Greenland. In Britain, it occurs mainly in the north and west during winter. Numbers appearing in Britain fluctuate considerably and large influxes occasionally occur, possibly associated with severe northwesterly gales. L. glaucoides is a very scarce winter visitor and passage migrant in Sussex; around 89 individuals in total being recorded during the winter periods of 1961/62 to 2010/11. Prior to this only 26 had been recorded in the county. Most records relate to individual birds observed in late winter or spring. The above pictures of a second summer bird were all recently taken during very overcast conditions on Benbecula in the Outer Hebrides.
