Met up with George for a look at the reservoir this evening, a fairly compact roost mostly towards the southern half. An adult Caspian, 6 Yellow-legged gulls (5 adult and 3 cy), couple of Argentatus-type herring gull, the Ring-bill/LBB cross and a small presumably LBB/HG. 5 adult Mediterranean gulls. 3 GBB (2adult and a 1cy). 15 Greylag flew down the reservoir, single male Goldeneye.
