On a grey sunday afternoon I went for a walk along the coastal path starting from Larmor-Baden ,a small harbour tucked inside the gulf. We had had a severe storm during the previous twenty-four hours. I noticed this gull on the pier because it was ringed and I took a record shot of it. The ring reads 4:GBW. Does it mean it was ringed somewhere in Britain ? I would very much like to know.And as I don't know much about gulls I hope I am right in assuming it is a lesser black-backed.
