Guiding on Anglesey yday, then out in the evening, hence late post!
A second winter Ring billed Gull in Holyhead Bay at 4pm looking east from the fish quay. Bird was feeding with just 3 Black headed Gulls and 2 Herring Gulls and was watched on the water and flying around the bay for 20 mins before flying NW, on its own, round the breakwater and lost to view. Worth checking the gulls in Beddmanarch Bay if your over that way, a cracking adult Med there yday.
