I snuck out between rain showers the other day to take some photos and when I turned my back this Cooper's Hawk flew in. He landed on the fence and was hidden so I attempted to pish him out. My high pitched pish got him really excited and he flew out and landed in a tree a couple of feet from me. Then he flew to this branch for a split second before realizing I wasn't a songbird. Then he took off. Pretty exciting 10 seconds of yard action.
