Glaucous Gull (Larus hyperboreus)


The Glaucous Gull resembles the herring gull but misses the black tips at the end of the wings and is a smaller relative to the Iceland gull. They are seen all year round but are most numerous in the wintertime when they fly down from Greenland. They hybridise with the herring gull and provide viable offspring.
