At 11:25 am, while traveling north on I-71 just south of the Franklin County landfill, I observed a large falcon that I believe was a Prairie Falcon. I observed it for ~10 seconds as it flew across an agricultural field to the SE of I-71. I was the passenger, but did not have binoculars. I couldn't see any "field marks," but the size, shape, and erratic flight style all pointed to Prairie Falcon. The bird was significantly larger than a kestrel or Merlin, but slender and floppy compared to a peregrine. I have a lot of experience with Prairie Falcon and this bird struck me with 100% PRFA vibes. I report it as probable because of the nature of the observation, which leaves much to be desired. I'd be driving nearby side roads now if it weren't Thanksgiving or I didn't love my in-laws. Here is a map of the sighting from ebird for those who may follow up : http://ebird.org/ebird/view/checklist?subID=S26004595 Happy Thanksgiving, Jack Stenger, Cincinnati, OH ______________________________________________________________________ Ohio-birds mailing list, a service of the Ohio Ornithological Society.
