Says you, to me hitting golf balls in the direction of a bird is most likely going to kill it.  It said he hit towards it multiple times, if he was really trying to just scare it away don't you think you'd give up after the first few were close and didn't scare it off.  He was obviously trying to hit it, which would most likely injure or kill it.  It's a freaking bird they aren't that tough, plus it's a predator so all you gotta do is bust that things eye or wing and you pretty much render it unable to hunt.
