The documentation form by Jim Fuller is the only one submitted and forms the basis of this record. Other observers include Ann Johnson, Chuck Fuller, and Jane Fuller. | Elimination of similar species: Herring Gull (first winter) compared above. [...] I first saw this bird flying, and the underwing was translucent throughout the primaries to the end of the wing (Herring Gull had dark outer primaries, although most also had a lighter window type area medial to this dark area). The bird was about the same size or a little smaller than the Herrings. The upperwing in flight was much lighter in the primaries than the first winter herrings. [...] It had a more rounded head than the herrings. [...] It's color was more uniform than the herrings and also lighter- a brownish color. There was a dark smudge around the eye. The feather edging (whitish) provided more contrast with the brown on the back than in the herrings, and the folded tail was brownish, not black. When in flight the tail band was brownish not blackish like the herrings. | The original documentation form event lasted from 13:15:00/13:45:00.

According to NGS, Glaucous-wing has less mottling or scalloping. The Keokuk birds were obviously mottled. | The original documentation form event lasted from 11:05:00/11:30:00.

The documentation form by Thomas H. Kent is the earliest and the one that forms the basis of this record. Other observers include Dick Tetrault. | Elimination of similar species: We were looking for a Swallow-tailed Kite reported the day before, but this bird did not have the forked tail and contrasting black and white of that species. The underparts and tail were not white as would be expected for Black-shouldered Kite. I did note any contrast in the upper wing (white posterior edge of inner wing) -- I may not have seen this or this could of been a first-year bird that lacks this mark. The failure to flap wings and overall gray color is inconsistent with any falcon. I saw a Swainson's Hawk earlier in the morning and its contrasting underwing was very different than this bird. A Red-tailed Hawk was also seen earlier and had an obvious buteo shape. | The original documentation form event lasted from 10:27:00/10:29:00.
