After Stanwell Moor I made a visit up to Staines Reservoir, which was fairly quite, but the American Horned Lark still present, plus two Black-necked Grebes, three Peregrines noisily chasing each other over the south basin briefly and a Little Ringed Plover was heard but not located as it flew by on the southern basin.
