One at Westfield Pill,along with a couple of Common Sandpipers and single Black Tail Godwit.It has probably been there since at least last Monday.Today is the first time I have had good enough views to confirm my initial suspicions.Best looked for on the mud in front of the eastern reedbed.It does not associate with the Common Sandpipers,instead favouring a narrow strip of mud underneath the trees,where it can be very difficult to find and see.
