The documentation form by James Scheib is the only one submitted and forms the basis of this record. Other observers include Sharon Scheib. \| Elimination of similar species: I assumed a Red-tailed hawk until I put my binoculars on it and saw that it lacked the patagial marks of a RTH and had a dark mottled pattern underneath including the breast, thus really getting my attention. I next assumed a Rough-legged Hawk and looked to the wing pattern, but the wrist markings were dark commas, not the large carpal patch in a RLH. See above for RTH & RLH. From the first I never considered it to be a Red-shouldered Hawk because of the highly contrasting patterning of the underside as opposed to the duller, finer underside of the RSH. The size was also that of a larger hawk. \| The original documentation form event lasted from 09:00:00/09:02:00.	Iowa Ornithologists' Union \| MS 166	33	28
