We saw this gull during our whale watching tour off Reykjavik. It's possibly at Svatbakur (Great Black-backed Gull, lanus marinus). (Or maybe it's a Lesser Black-backetd Gull.)
Sightseeing in Iceland
This photo was taken as we drove up and away from the pretty little town of Seyđisfjörđur. The weather improved later in the day.
