I don't know about the celebrity part... Based on the information on the first post, the act looks like its premeditated. He "accidentally" killed the bird you might say but come on, he is obviously hurling golf balls at the direction of the bird. And as most people and golfers know, a golf ball can crack tempered glass in car windshields and it can obviously hurt/kill birds.
Put it this way, you have a dog that is 30 feet from a kid. The dog is barking, but not necessarily at the kid. The kid tries to "scare" the dog away by throwing decent sized rocks at it. He unknowingly hits your dog. Your dog dies. Unfortunately your dog is a competition winning dog (this part shouldn't matter though). Would you try to get compensation from the kid's parents or just accept the fact that its an accident and that your pet dog that you love is gone.
This might be a wrong analogy but its the best that I can come up with. Dogs are considered property and an endangered bird is/should be worth more than a dog in my opinion. Its not about the money but about the punishment and taking responsibility for your actions. Although one can argue that you can just punish the kid in the analogy that I made above, in the golfer's case, a big fine.
