I live on a ridge top in East Tennessee. I have a large deck accessed by four patio doors. The deck overlooks the valley and the forested ridge on the other side. Usually there are 3 to 10 hawks/bussards/falcons cruising over the valley looking for a meal.
Yesterday a dove crashed into the kitchen patio door at top speed and was stunned. It was lying on the deck and my wife went to help. As she reached down to pick it up, a falcon? swooped in and took it away. I said falcon because my wife described it as slightly larger than the dove. I have seen the prey birds catch other birds, snakes and small animals but this incident tops my list of weird. Obviously I need some education about birds of prey in tnis area.
