Woodpecker Holes in Fallen Bradford Pear Tree

I was cleaning up some storm damaged trees in my neighborhood over the last couple weeks and noticed this. I found a series of small holes in a Bradford Pear tree trunk made by a woodpecker. I am guessing the tree had about 10 holes in it.

Of course, the picture would have been much nicer if I would have actually gotten a picture of the bird making the holes!
