It's funny how an odd pose can throw you, isn't it. This guy had me pondering for a long time as to what it was.

My morning picture... well done to those who spotted the two birds, one each side of the big rock, not far from the right and left hand borders. Unless I'm very much mistaken they're Lapwings and well done to JJ who ID'd them too.
