It is helpful you have fence posts in three of the four pictures. In one picture it is sitting on a rail next to a post. That bird would have to have one foot over the other if it was standing on the post. The next two pictures show a metal cap larger than the post. It is obvious it has plenty of room for both feet on the post alone.
Are both posts 4X4? If not, what size are they?
If the last two is a 4X4, I believe it is small enough to be male Sharp-shined.

Subject: [Tweeters] "Our" Cooper's Hawk
Beginning on September 5, we have been visited by a very human-tolerant Cooper's Hawk 3 times. I'm pretty sure it's been the same bird all 3 times, anyway. Each time the bird shows up in our backyard, we can quietly watching, moving around with our cameras taking pictures, and the hawk just does whatever it wants. Today I was outside doing a little yard work and heard an almost sweet-sounding little call that I didn't recognize. I looked around to see what bird could make that noise and there was the Cooper's Hawk sitting about 20 feet away on a lattice. I slowly stood and called Bill, who came with his camera. He took a few pictures, then the bird started hopping along the fence railing, continuing to call. Every so often it would pounce into one of our shrubs and passerines would shoot out the bottom. It's a fairly long back fence and the hawk patrolled the whole thing, finally sitting at the corner, from where it flew off.
Has anyone observed this behavior where the hawk calls softly while it's stalking its prey? The bird kept up its little crooning call the whole time it was in the yard this time (it hadn't done this previously).
The first 2 times we saw this hawk, it was in pristine condition. This time something has happened to the feathers on its head. I've created a Flickr album for some of the pictures we've taken of this hawk. The first three are from Sept. 5, then two from Oct 2, and 4 from today.
