Beaver chews through tree limb: close up footage: See how beavers do it!

( EDITOR'S NOTE: If you want to see what happened just before this video; and see how the tree ended up on its side; watch this video link: https://www.youtube.com/watch?v=l0SKRR6K620 ). I was in the right place at the right time to film this wild beaver chewing a chunk off of a fallen tree trunk. I tried to get in very close to provide a real up-close look at how they do this.
