Another possible YLG

I  am more hesitant now about reporting definite Yellow Legged Gulls, especially 2nd winters, but a bird I kept looking at today had some good features on it, I wasn't totally convinced by the tone of grey, head shape and bill at some angles, but it looked pretty like one most of the time and was aggressive and bigger than nearby adult Herrings. I await confirmation, but here are a couple of shots;

 

Also present 130-150 Wigeon, 1 Little Egret, 2 Skylark, 30-40 Teal, c50 Lapwing, but not much else.
