Well, as long as someone has brought a Mothman thread to the top . . . you could find out more about this Winged Weirdie by ordering Loren Coleman's recent book
Mothman: Evil Incarnate:

. . . And I'm not just saying that because I wrote "The Mothman Annotations," which take up 1/3 of the book! Really!
Seriously, though, for a short and succinct version, nothing beats the chapter on "West Virginia's 'Mothman'" in
Strange Creatures from Time and Space (updated as
The Complete Guide to Mysterious Beings). To tell you the truth, I found all the contactee shenanigans in
Mothman Prophecies tiresome after a while. Anyway, most of the other odd events associated with Point Pleasant and Mothman are scattered throughout
Strange Creatures/Complete Guide.
The
Strange Creatures chapter was adapted from the Keel article, "West Virginia's Enigmatic 'Bird'," from
Flying Saucer Review July 1968, which has been reprinted in
Searching for the String: Selected Writings of John A. Keel, edited by Andy Colvin, if you want to read the raw, earlier incarnation of the account.
