Intelligent Rooks

So the snow is here now and it is colder, too. The birds will find it harder to find food so I expect more to come into the garden for the free stuff I have put out. I managed to get a shot (poor quality, I know, but they don't let me get close) of this Rook pulling up the string from which the peanuts and bird-cake hang, holding the food on the branch with one foot and then pecking away. Got to admire the Rooks, though the songbirds don't get a chance.
