Hi Lorant
I,ve seen quite a few waders do this over the years. The flexible end is supposed to be to do with locating and getting hold of worms etc with the beak underground. This one is probably just stretching like we do.
Nice pic anyway- shows it well.

Hi Lorant ,pretty sure that the flexible bit on the upper part of the bill is used for the locating and catching of worms and other food when the birds are probing in mud or soft earth,noticed it a lot with Snipe.Very much like the one legged pose on your Godwit and the odd lifted feather.

Fun image showing these birds' amazing beaks and their flexibility. They do all their foraging underneath the sand/ground, so we don't normally see this behavior.
