Please Help Identify this Bird!

So I'm not a bird guy.  Not that I don't like birds, I just don't know a darn about them.  That being said I was hoping someone could help me figure out what I have here.

This little fellow was in a tree overhanging my driveway early this week and making quite a racket.  I am guessing he is some type of hawk, but I can't be sure. Any help identifying this species would be appreciated!

p.s. Sorry for the poor quality of the pictures, I was in kind of a rush!
