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.
