Pileated Woodpecker

Have you ever wondered what in the world they are pecking all the way to China for? See our oak trees have worms in them. A little underexposed so I had to use a little touch up. Thought it was an interesting photo. They came in a pair today. Had lots of good shots but almost all were underexposed.
Thank you for your comments.
It really got hot here today I got a little over heated and had to come in for a while.
