Please forgive the rather bad photo, it was taken through a misty window. I have been watching this chap for some weeks now. He or she comes regularly to investigate the cracks between the tiles on the barn next door and in the barn wall. Why peck at the frozen bark of the local trees, when you can have insects in ready-made cracks?
The barn is a real attraction for the local birds. I can stand at my window and watch nuthatches, redstarts, treecreepers, bluetits and more feasting on the insect buffet offered by the old barn. Allowing the bird life to come to me certainly beats wandering around in the cold weather clutching a pair of binoculars.
