Prairie Falcon?

Another somewhat rare find in this part of Minnesota, I found this guy on the way to work yesterday and I to go back today to get a picture. He's not in a good place to stop and take pictures so I had to snap a few quick and go. Wish I had better shots, but according to my sister's real live bird nerd friend, this is a Prairie Falcon...also a little out of his norm because of the extreme winter.
