Somehow I missed this. What fantastic creature! Yes, a Red-tailed. Very powerful looking. Wouldn't want one mad at me.
My son and I saw a big hawk get clipped by a fast moving car on the highway. Bird cartwheeled over a few times and luckily landed on the side of the road, out of traffic. It was alive, but stunned, so we picked it up (with a blanket!) and waited for the bird rescue to come get it. I thought that bird was big, but much more slender than a Red-tailed. Turned out it was a female juvenile Northern Harrier. It was fine, bird rescue released it in a couple of days. I think I see it along that road sometimes, up on the power poles.
Northern Harriers have owlish looking faces.
