We have one behind the house who hits the same tree over and over and hasn't seemed to make a dent in it. He is out there right now actually! You can hear him a mile away. I have gotten a couple of decent shots of him over the years by sneaking up when he is drumming.
I believe that when they drum like that they're sending a message. They find a branch or trunk that is hard enough too resonate so they can communicate with other piliateds over the miles. When I this shot he was ripping into our tree looking for bugs.
