I was photographing a Burrowing Owl on Cape Coral, FL, from a distance, when a Cooper's Hawk flew directly at the owl and swiped at it. The Owl's response was to fly quickly low and away from its burrow onto the ground some distance away and puff itself up as much as it could. It walked around puffed up for some time. The hawk flew beyond into a far distant tree. The owl came back near its burrow and went underground. Not perfect photos, but it shows the amazing behavior we had never seen before. Lucky Owl!
