The documentation form by Mark Proescholdt is the earliest and the one that forms the basis of this record. Other documentation forms by Beth Proescholdt were submitted later. | Elimination of similar species: Harrier - tail was not right and long enough for harrier and bird was not right color underneath. Nighthawk - Our bird was much bigger than Nighhawk and had no white patches in its wings. Turkey Vulture or Eagle - Our bird was much smaller and had long, narrow pointed wings. Accipiters - Body shape was wrong and did not have extra long tail -look like accipiters have. Osprey - Wrong body shape for osprey and no white markings on our bird. Buteos - Wrong body shape again even for Swainson's Hawk which can appear to have pointed wings when seen overhead. Buteos have much broader wings and should show some white contrasting colors underneath. Falcons - Our bird was too big for a Kestrel or Merlin. I don't think Merlins ever have leisurely, slow flapping flight. This bird didn't fly right for a Peregrine and the body proportions were not right for a Peregrine. I've seen Peregrines fly in a slow, leisurely manner and this did not seem to suggest a Peregrine at all. A Peregrine or Prairie Falcon should show some light-colored areas underneath. Also, a Peregrine's tail tapers down to a rounded end and is not squared off and flared at the end. | The original documentation form event lasted from 19:35:00/19:35:00.

The documentation form by Andrew S. Fix is the only one submitted and forms the basis of this record. Another observer was Craig Harms. | Elimination of similar species: Only species for possible confusion is Common Goldeneye, which was readily separable by the lack of dark lateral breast band in Common Goldeneye. Lack of dark back with linear row of white spots parallel to midline in Common Goldeneye and the overall whiter appearance of the Common Goldeneye. The final spot of the Barrow's is supposedly a cresent [sic] however this was not clearly evident in this bird, as the spot it had was suggestive of a cresent [sic] when compared to the nearby Common Goldeneye. Voice and behavior were not helpful in separation in this case. | The original documentation form event lasted from 11:30:00/12:00:00.
