looks a bit big to me to be a greenshank, imo looks and feels more like a black-tailed godwit.
Is it a bit too white underneath for a Black-tailed Godwit?
It's just a bit shorter in body length than the Black-headed Gull, which points to it still being possibly a Common Greenshank. Legs look too pale for a Black-tailed Godwit or Bar-tailed Godwit.
Actually there are 2 greenshank in the photo, as well as 2 redshank near the edges.
Greenshank is our palest wader, the only species that will ever look mostly white at a distance, apart from the much smaller sanderling. Both godwits are distinctly darker and browner, with darker blue-grey legs and longer, stouter bills.
