The documentation form by Beth Proescholdt is the earliest and the one that forms the basis of this record. Other observers include Eugene Armstrong and Eloise Armstrong. | Elimination of similar species: Peregrine, imm male, is similar. See above. It was near the size and shape of a Peregrine with long tapered wings & slim body. I knew this wasn't a Peregrine (but an immature male Peregrine & an imm. Mississippi Kite are similar). However the slim, pointed wings of this bird had a different shape; the tail was longer, proportionately, than a Peregrine's, & squared-off rather than tapered like a Peregrine's. I couldn't see if its tail flared at the tip, but in the gap where we had a second, very quick look, Eloise noted its twisting of the tail which is a Mississippi Kite trait. But it was the wing beat that determined absolutely that it was a Mississippi Kite- light, bouyant, [sic] floppy, leisurely, like a moth-so different from the powerful, rapid, direct flight of a Peregrine, and different from any other raptor's flight we have observed. | The original documentation form event lasted from 10:30:00/10:31:00.
