Branta leucopsis; Barnacle Geese are passage migrants. They spend the winters on the British isles and breed on Greenland. During spring and autumn they stay a while on Iceland. I saw many of these birds in spring in northern Iceland in the regions around Sauðárkrókur. Apperantly in the autumn they stay in southern Iceland for a while before heading south to their winter residence. Branta geese are typically black/white birds. On Iceland I noticed that the Barnacle geese have a bluish gloss.
