Fairly large wading bird on Humber mudflats. Suspect it may be a sandpiper or Dunlin?
No interactions present.
Common sandpiper is mainly a summer visitor and would be smaller. Also not dunlin and looks too long-necked for knot. The legs also look as if they could be pretty long.
Do you have more information e.g. beak and leg colour, rump, tail and wing markings?
If I had to make a guess, I might go for something like Ruff, but would want to exclude godwits, greenshank etc. from any additional information.
Although there is the original comment about a "fairly large wading bird", assessing the size of the bird is very difficult as there is nothing against which to compare in the picture. The shape of the bill with a slightly down-curved tip excludes godwits, greenshank and knot but does strongly suggest dunlin, a point also supported by the basic 2 tone grey-white plumage and the shape of the demarkation between the 2 colours on the upper breast.
Dunlin was the 2nd choice of the observer, and there is nothing at all in the picture to suggest this is incorrect. I wouldn't describe a Dunlin as a large wader, but this IS a Dunlin.
I has dismissed dunlin because of size, but would agree about all the features mentioned above
Sorry about my misleading comments. Unfortunately it was some distance away and not close to anything to scale against. I should have put medium sized as it was not as big as a curlew but probably about lapwing sized. Gulls, LBJ's and waders...all a problem to me!
