We were just heading back from Arnold's Marsh on Salthouse Broad to the Cley visitors' centre when we noticed a couple watching this bird. I had no idea what it was but the man thought it was a Ruff.
I did some internet research and it seems that this is indeed a Ruff, although its strange white-headed appearance can evidently cause confusion!
Update: do read Stewart's informative comment below. Thank you, Stewart.
