This big bird was surveying the back hill this afternoon while I was outside tending the chickens. He was nice enough to wait for me while I went inside to get the camera. Unfortunately, my camera doesn't zoom enough to get a really clear picture, but you can certainly tell he was a big dude! I'd estimate he sat nearly 2 feet high with a 2-3 foot wingspan. From what I can tell, it appears that he is a Cooper's hawk.
