The documentation form by Thomas H. Kent is the only one submitted and forms the basis of this record. Other observers include Jim Fuller and Dick Tetrault. | Elimination of similar species: The falcon shape was clear to us. The bird was flying directly into a strong southwest wind, but I don't think an accipiter's wing could be that pointed even in a strong wind. The bird was too large and plain to be a kestrel and the flight pattern and behavior were unlike any of the many kestrels seen that day. The light color and open farmland habitat favor Prairie over Peregrine. A Merlin would be smaller and darker. However, I would not have identified this bird as to species with out seeing the underwing pattern. | The original documentation form event occurred at approximately 12:00:00.
