A large, pale gull that breeds in the Arctic. It is a 4 year gull, meaning it takes 4 years to reach maturity. They can grow to be very big, almost matching the great black backed gull in size (the largest gull in the world). Call is a typical "laughing" cry, like a herring gull's. These were the only Larus gulls I saw in the sea ice, with this particular individual being a juvenile (ID'd as a glaucous gull by the pink feet and black tipped bill).
Breed on cliffs, often seen inland but I also saw them quite far into the sea ice off NE Greenland
The morning I saw these birds was very foggy, so my camera had difficulty differentiating the white and grey bird from the white and grey... well, everything else! These few came out clear enough to see it
