Our not so little visitor

After getting out the bird book, we think it is a juvenile Coopers Hawk because it had yellow eyes vs the adult reddish eyes. Our guess it was close to 15-16″ long.  It sat in our tree for about 45 minutes or more.  Flew off but came back about an hour later.  It was quite a beautiful sight to watch!  Also found a half eaten chipmunk on the ground where it had been sitting.  Thankfully, I got it scooped and thrown away before the puppers finished it off.
