Looks like it could be an Broad winged Hawk.
Here are links to a website with pics. At first I thought it might be a Coopers hawk as they are pretty well known for hunting at bird feeders, but I don't think they are in Eastern US. And the Coopers hawk site gave a link to this broad winged hawk. Looks an awful lot like the picture here.
