Both the Ring-billed and Yellow-legged gull there this evening, and 1 Adult Mediterranean. The R-B gull is usually present much earlier (3pm), and often 'tucked-up for bed', before the majority of the larger gulls arrive. At 4.45pm there was a mass arrival of large gulls dropping down from the field just to the east, unfortunately the light was going too quickly for a really good look. A Greylag amongst the Canadas.
