A common tern dropped into the bay during the afternoon showers. It took some time to confirm the ID. Thanks to Peter and Graham for the clinching photos which eventually ruled out arctic. Ring necked duck showing very well indeed off Prospect Place. Two yellow legged gulls (regular 3CY at Channel View and 4CY in Bay). Two 2CY med gulls also. Hundreds of hirundines in the bay including my first house martin of the year.
