What is this?

Just took this picture - was sitting at the computer checkin out FM and glanced outside to see this guy. Figured I'd ask here...

You've either got a juvenile Cooper's hawk or juvenile goshawk. They are pretty close in size, and there is size variation even within species, so size isn't the best indicator. Since the juvie goshawk has a strong white line over the eye and the juvie Cooper's has a buff-colored head, as well as a couple other more suble field marks, I'm going to lean toward the Cooper's.

Looks like a Cooper's Hawk to me.

There is also the slight possibility it could be a sharp-shinned hawk. The only difference between the immature SSHA and the imm. COHA are size and tail shape. The SSHA typically has a squared tail were the COHA's tail is rounded. But I would agree with catfish and boat fixer, probably an immature cooper's hawk.
