Short abstract from the book:
Iceland gull is an uncommon visitor during migration and winter in the Faroes, and rare during summer. No Iceland gulls have been ringed in the Faroes. One ringed 31 July 1954 in Northern Strømfjord, West Greenland, was found dead on 4 December 1954 in Trongisvágur, Suðuroy, 2,230 km ESE of the ringing site.
