It was -22 this morning so I couldn't move quick enough to snap a picture of the crows close up, but here we see them after they retreated to the safety of the tree. Duke and I stepped outside this morning to start the car. (It was parked in the driveway and needed to "warm up" - that's an understatment.) At the end of the driveway were 5 or 6 crows. They were just sitting there with their feathers all puffed up to ward off the cold. Duke went into action, ran down the driveway and dispersed the crows. They were cawing up a storm when I snapped this picture.
The picture below is Duke enjoying the snow yesterday as he helped me start the car.
