Pro golfer Tripp Isenhour is charged with killing a red-shouldered hawk with a golf ball. He was shooting a commercial, and the bird was making noise. The Orlando Sentinel has some video of a red-shouldered hawk, so you can see the type of bird Isenhour killed, and an expert who talks about how making noise comes naturally to the hawk.
