Difficult image to manage...looks like a flying bullet! A bit tight in the frame and I too would tone down some of the sheen on the bill. Not my favorite wing position (which they were fully down), but still very impressive.
A stunning image and I agree with the praise others have given. However this is a Greater Yellowlegs---thicker bill base with a lot of paler colouring, bill gives the impression of being very slightly upturned, secondaries edged/notched white.
