"I'm not talking to you anymore!"

Out walking in my local park (again), I was on the hunt for a good duck shot, being as I am, rather fond of the quacking creatures. Naturally, none of them were cooperating, swimming away as soon as I reached for my camera. I did, however find these two ducks under a little tree. I'm sure they've had an argument - why else would the far duck have his back turned to his mate?
