Prairie Falcon

I had seen one in Nebraska once before, with no real good photo but very high in the air (you can see it is a falcon) and I had seen a couple in Wyoming. I went to one of my local places, adding a Western Meadowlark and hoping few more year birds. I got excited at finding maybe a Peregrine Falcon. At the end of my walk there was this lump on a bent tree:

It was too large for a kestrel or a merlin. Getting closer, and the light really was as bad as above, I got some photos of it. The couple of pictures in flight are from a bit of video I took. The line on the face and the white behind the eye make it a Prairie Falcon. Only in winter and early spring do they get this far East.

It flew low across a field of corn stubble to the next row of trees by a farm.
