I looked out the window and what I thought was a squirrel attaching a suet feeder was a Hawk, which surprised me.. i didn't have my camera. Then, it flew deeper into the bushes with a tremendous thrashing of wings. By the time I got my camera, it was gone.

About 5 minutes later I look up and see this. I don't know for a fact that it is the same hawk, but I did get a couple pics before it disappeared behind the tree-line.

It was overcast and the pics are silhouettes. I wasn't able to discern the ventral coloration. Can anyone look and suggest what kind of hawk it may be?
