At about noon today I saw a Falcon that appeared to me to be a Prairie Falcon in flight. I first saw it close flying up from the ground away from me showing its plain light brown back. It had pointed Falcon wings. There was a Kestral in the area, too, but this bird was too big to be a Kestral or a Merlin. As it flew higher, it appeared to be uniform colored underneath with heavy brown streaking. When it turned its head, lower than the eye, I briefly saw two vertical facial markings. It kept soaring higher, heading north & west out of view. I was at an intersection a couple miles north and west of Bayard.
