Hunting Cat

I was at Birsay Palace and saw this cat which I'm sure I've photographed before. It went up a path and leapt onto the post. The shot isn't too sharp.It only sat for a few moments before pouncing onto a mouse or something but I think it missed. I was over on the Brough of Birsay earlier. I saw my first nearctic gull of the winter- a glaucous gull, also male hen harrier, lots of dunlin, ringed plover, redshank and turnstone and a few purple sandpiper etc.
