woodpecker walking

I suppose I never really thought about woodpeckers that much. I've always thought that they landed on a branch and sat there while pecking on a tree for insects but today I learned something . I watched this woodpecker walk up to a tree and then walk up the tree. I thought it was amazing. After all, the woodpecker has no hands; just two feet and it has to take one of them off the ground (or tree in this case ) to take the next step so he is supporting his whole body weight while parrallel to the ground and all on one foot. I thought that was really amazing. Animals are so much fun to watch.
