Mediterranean Gull - adult with yellow ring on right leg, black letters AT.HT - appears to be from Germany (or possibly Sweden).
Black-headed Gull - adult with black ring on left leg, white number & letters 2AVL - appears to be from the West Midlands.
At least 20 Mediterranean Gulls in the gathering, probably more.
More information on the North Wales Great Black-backed Gull B:147, it was seen in Castle Bay on Skomer on 5th September, 15 days before it was recorded nearby on Dale Airfield. A second bird from the same colony, B:160, which was seen at the Gann on 9th October, was seen on Skomer (South Haven) 5 days later on 14th October. Fascinating stuff!
