Old Oliver & The Hawk

Husband is pulling machinery out of sheds today with this old Oliver tractor. Normally, he would use the skid loader, but its in the repair shop, as mentioned in yesterday's post.
As I stepped out of the house a few minutes ago to snap a picture of the tractor, this big bird was soaring high above our farm buildings and trees, riding along on a convenient air current------it happens to be extremely windy here today.
Here he is again, appearing to be tangled in tree branches, when actually he is high above them. I would imagine this bird is a hawk of some sort, but I'm thinking its not one of the usual red-tailed hawks we see.......but, I could very well be wrong about that. If someone can tell what it is......let us know in the comments.
