Cooper's hawk comes by for a visit

Was about to leave for a teaching assignment this morning when I looked out the second story window and saw an immature Cooper's Hawk sitting in the tree to the north of us. I ran downstairs and started to take some pictures through the front window but there were many branches in the way and I also noticed the squirrels were returning to the garden not seeing the hawk in the tree. I went outside and the squirrels ran off and I got a few more pictures of the hawk before he flew off!
