观察细节
I frankly thought this was a LBBG x RBGU hybrid (if such a thing exists). Anything else did not really come to my mind. Common Gulls in Germany are daintier than RBGU. George A suggested this species and sent photos to leading gull experts and the consensus is Larus canus. Likely ssp kamtschatschensis. Likely first county record. The bird was somewhat taller then surrounding RBGU, but smaller then the nearby LBBG. Back coloring as dark as LBBG (maybe a little lighter). In flight the clean white tail was obvious. I do not remember the white spot pattern on the wing tips.
