A Squirrel Enjoying Dinner

Today was going to be cool outside with a chance of storms.  I opened the windows after waking up to draw in some cool air.  After the last few storms rolled through I heard something gnawing on wood from inside the living room.  Our property borders a creek that's maybe about 200 feet from our door.  I can often hear beavers chewing on the trees along the creek.  I went outside to go down and scare them away to try and save what trees are left along the creek.  I didn't get too far before I realized the gnawing was coming from up in a tree along the driveway.  I went back inside to get the video camera and this is what I recorded.
