The documentation form by Ann Johnson is the only one submitted and forms the basis of this record. | Elimination of similar species: This was a classic case of delayed reaction as I began sorting through in my mind as I drove down the road. The large size and bulk of the bird, plus the broad, rounded tail made it an obvious buteo. After double-checking all phases of the rough-legged hawk in Clark's Hawks, I once again eliminated rough-leg because of the nearly all white underparts. However, redtail wasn't fitting either, even a light phase, and a few miles down the road the ferruginous crossed my mind. I pulled off the road, made a few notes, and began researching with the guides at hand. The most troublesome field mark was the 'white tail with gray band.' I have seen numerous redtails give the white rump appearance but none have had the distinctive white tail/gray terminal band. There was absolutely no dark patagial marking on the underwing. The combination of field marks (or lack thereof) would seem to approach an immature Krider's redtail. I eliminated this bird because of the appearance of one, wide gray tail band and the more uniform coloring of the body - very little white mottling. Although I wish I'd had a longer look, I came to the conclusion that the combination of what I had observed pointed toward an immature ferruginous hawk. | The original documentation form event lasted from approximately 09:00:00/09:01:00.

The combination of slightly smaller size, distinct head shape, bill color and shape, dark eye, and slightly darker mantle and upperwings are sufficient to eliminate Ring-billed Gull. | The original documentation form event lasted from 15:42:00/16:53:00.

Ring-billed Gull never shows this much brown in any plumage, has a dark tail band in immature plumages, has a different wing pattern, and is structurally different from California Gull. Herring Gull is more similar in first-basic plumage, but always shows a pale window on the inner primaries, lacks the double dark bar effect in the innerwing, is larger, and very rarely shows a strongly bicolored bill. | The original documentation form event lasted from 10:55:00/12:24:00.

Other observers include Don Stolz, Carole Stolz, Eugene Armstrong, Eloise Armstrong, Pam Allen, Reid Allen, Ann Johnson, Jim Dinsmore, Jim Fuller, Bob Cecil, and Aaron Brees. | Elimination of similar species: My experience and references of Buff-bellied Hummingbird suggest that the cinnamon color, extent of this color toward the throat, cinnamon rump/back, and white eye spot do not fit this species. I believe that the features shown in the photo of the Arizona 'mystery' bird in Field Notes are a perfect fit for the Des Moines bird. I do not know of specific information on bird trafficking in Iowa.

The documentation form by Thomas H. Kent is the only one submitted and forms the basis of this record. Other observers include Cal Knight, Bernie Knight, and Jim Fuller. | Elimination of similar species: Herring Gull --see above. [...] The bird is not any larger than some of the ring-bills--some of the ring-bills are smaller. The larger ring-bills are almost as big as this bird, and it is distinctly smaller than a number of Herring Gulls in the same field. The bill is much smaller and thinner; the head is small. [...] The striking thing about this bird is the size, bill shape and head shape compared to the nearby herrings and very distinct smudge through the eye." | The original documentation form event lasted from around 09:10:00 for several minutes and 15:55:00 for many minutes.
