Pileated woodpeckers

Yesterday I went for a walk on the camp road, and before I had been walking for even a minute, a pair of HUGE pileated woodpeckers flew in from somewhere and landed on a couple of trees just a few yards off the road. I've only ever seen one of these birds a handful of times, and I've never seen a pair before. They were about to settle in to pecking some of those peculiar, rectangular holes, and I was trying to figure out how to use the camera on my cell phone when a snowmachine came by and they both flew off.
