The documentation form by James P. Mattsson is the only one submitted and forms the basis of this record. Other observers include Michael Bornstein. | Elimination of similar species: [...] The bird was most similar to the dark phase rough-legged hawk (Bureo lagopus) in size and general shape, but the latter species lacks the deep rust coloration on the upper wing coverts, scapulars, and upper back, and also has some dark banding on the outer one-half of the tail. Although by no means a conclusive characteristic, the subject bird did not hover during the period we observed it, a characteristic typical of hunting Rough-legged hawks. Dark phase Swainson's hawk have much darker, barred flight feathers and tail when viewed from below than that of the subject bird. | The original documentation form event lasted from 12:30:00/12:45:00.

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.
