| Occurrence Remarks |
The documentation form by Steve Dinsmore is the only one submitted and forms the basis of this record. Other observers include Eric Munson. | Elimination of similar species: Am. Kestrel was eliminated because of the lack of a rusty back, rusty tail and the unbarred undertail. Peregrine and Prairie Falcons eliminated by larger size and lack of strongly barred tail. Sharp-shinned and Cooper's hawks eliminated by the longer tails, lack of strong barring underneath tail, and by the broader, non-painted wings. | The original documentation form event occurred around 17:15:00. |
