THE ICELAND GULL Larus leucopterus, Faber
Reading edition
This species is very closely allied in plumage and habits to the preceding. It is a winter visitor to the shores of Scotland, only coming south in severe weather. It breeds on Jan Mayen Islands and Greenland, and is only a winter visitor to the island whose name it bears.
Except in size it is almost a counterpart of the Glaucous Gull, but the orbital ring is flesh-coloured, and the legs yellowish. Length 22 in.; wing 16 in.
