| Occurrence Remarks |
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. |

| Event Remarks |
Weather: sky overcast, winds ENE 10-15 mph. Lighting: flat, very little contrast. [...] Five minutes later, Michael and I returned to the area, and what appeared to be the same bird flew across the road about 100 meters ahead at a height of perhaps 5-10 m. [...] By the time we were able to get binoculars on the bird it was 150 m away. It flew low and landed in a tree about 250 m away. |
