Interesting thought, I still see a very good plumage for a 1CY Curlew Sandpiper, and dismissed the unusual bill as mud-covered, partly because the legs seem to have the same colour.
Looking at the pictures again and TRYING HARD, I find the PP on the short side for a Curlew SP. This might be due to photo angle and a foreshortening effect, but normally Curlew SP has slightly, but clearly longer wings, which the wingtips often crosses above the tail and are longer than the tail (evident when looking from behind). I found this most clearly evident on 1CY birds (reason?) and when clearly present, a good character against Dunlin.
Examples are here:
This can alltogether produce a clearly different rear than that of a Dunlin.
In this bird this jizz isnt there, maybe this (together with a hump-backed, broad-shouldered"-look, adds to the "plump-end" Knot-jizz, Roland?
But I still like the answer of a normal Curlew SP with mudcovered bill and legs (and the PP is clearly within variation for Curlew SP, especially when a foreshortening effect and a "single-picture-effect", concerning the hump-backed-look" is taking into account)
I hope my views are understandable!
