A scramble of Sanderling

High tide and what does your average Sanderling want to do? Scramble up on to a rock out of the way and have a sleep with one's mates is clearly the answer.
They are just coming into their breeding plumage - gone are the black and white clockwork toys of the winter but the glorious deep red chests of the summer have yet to arrive. We won't see much of them as that is reserved for the Arctic breeding grounds.
In the late afternoon, a final boat trip before our contrary migration south to try and find a cave on the far side of Eaval. We had detailed instructions form a local crofter and it was lucky we had as it would have been the easiest thing in the world to miss. 
An impressive stone lined shelter hidden from view half way up the flanks of the mountain. Even though we had trod the hill well before, every time one goes out, one seems to find new things!
