Oh no it's (a) Knot.
I Popped over to Manor Farm at lunchtime to see if the Knot found by Chris G was still there.
It was and showing very well from up by the top path - just as well really as I didn't have time to go searching for it. Only my second ever in the county and well worth being late back to work for.
Also seen in a very brief visit were 2 Little Egrets, a Green Sandpiper, a few Lapwings and a group of Black-headed Gulls.
