This is a short video/slideshow of a Pileated Woodpecker. The Sound of a Pileated Woodpecker is very distinct and can be heard for a great distance. This is one of the largest types of woodpeckers. They make a lot of noise when pecking on a tree and can usually be heard off in the distance pecking away. The tree bark will often shower to the ground with the onlooker wondering what is up there causing all this disturbance.
What is interesting is when you hear a Pileated woodpecker call and then you can hear another one in the distance call, then another one even further out.
