Ring-billed gull - Llys-y-fran

No white-wingers tonight, but the Ring-billed gull was still there. It came in after 5pm along with majority of other gulls, and after a brief preen, tucked its head under its wing and adopted its usual posture. Prior to that only 250 gulls on the water which grew to about 2,500 with more still dropping in as I left at 6.15pm. Again vast majority were LBB, perhaps 100 Herring gulls, 2 adult GBB and a 1st winter bird, <10 Common gulls, only 3 BH gulls, and what looked good for an adult Yellow-legged gull. A Red kite was cruising low over the field, looking for trout remains perhaps. 10 GC grebe inc 2 pairs displaying. 8 Tufties, 5 Mute Swans, pair Goldeneye and 6 Heron, one of which got the attention of an adult GBB gull when it appeared to find something in the margins (fish remains?).
