Thanks to all of you who have posted your Common Nighthawk sightings on eBird. Yes, I realize it is not data from a well-designed study but Cornell University can tell it is valuable to them and their worldwide study of birds. Ultimately this benefits all of us in the birding community. Enjoy the fall migration, Matt Valencic Geauga County ______________________________________________________________________ Ohio-birds mailing list, a service of the Ohio Ornithological Society.
