Was Woody Here?

There are times that I've heard the sounds of a woodpecker outside my window, but I haven't seen him.  The other day I was looking at something in the yard and I noticed these almost perfect circles in one of the trees.  I wondered if the holes might be from a woodpecker, so I Googled it, and yup, they are definitely from a woodpecker.  I will see you one day, Woody!
