Dungeness Bird Observatory
Most of the day was spent watching gulls as numbers continue to build up. The highlights were a first-winter Glaucous Gull at the Patch for a few minutes in the afternoon and a minimum of five first-winter Caspian Gulls. The latter were all roosting near the lighthouse during the worst of the weather in the morning. Also of note was an apparent first-winter Glaucous x Herring Gull hybrid and three Mediterranean Gulls. Sheer numbers were provided by at least 3500 Black-headed Gulls, 2500 Common Gulls, 7000 Herring Gulls, 500 Great Black-backed Gulls and 200 Kittiwakes.
