Iceland Gull (Larus glaucoides) is common along the Icelandic coastline during the winter months. It is a breeding bird in Greenland and on the northernmost islands of Canada. It is however only a winter guest in Iceland and by the end of March it has usually left the island.
The Iceland Gull is very similar to the Glaucous Gull (Larus hyperboreusstundu) which is a breeding bird in Iceland. The Iceland Gull is smaller, its head is shorter and more curved, the beak is delicate and the wings longer. It is also a more agile flyer than the Glaucous Gull.
