The documentation form by Steve Dinsmore is the one that forms the basis of this record. Other documentation forms by Jim Dinsmore, Bob Myers, Robert Cecil, Ann Johnson, Jim Fuller, Michael K. Thomas, and Mark Proescholdt were submitted. Other observers include Dennis Thompson, Betsy Myers, Eugene Armstrong, Eloise Armstrong, and many unidentified observers. | Elimination of similar species: The large size should eliminate all peeps. The bird was also larger than Sanderlings in direct comparison. Otherwise, the bill shape and dull yellow legs would eliminate Sanderling and Dunlin. | The original documentation form event lasted from 06:53:00/07:41:00 and 08:15:00/09:35:00.

I knew it was unusual and also knew it was a Red Knot from the breast and the bill size which I estimated as twice as long as the Killdeers bill and Dowitcher - bill was shorter than dowitcher and dark back. I tried to think of other shorebirds it could have been and the dowitcher species was what I could imagine, but its bill was too short. | The original documentation form event lasted from 19:30:00/19:35:00.

The bill was much too short for dowitcher. The bill was not curved enough for Curlew Sandpiper. These birds appeared to be partially molted into alternate plumage. | The original documentation form event lasted from 08:35:00/08:45:00 and 10:30:00.

[...] No other calidrine sandpiper likely to be found in Iowa combines the coloration, size, and proportions of the Knot. The only species that combine the overall grey coloration and the heavy straight bill are Sanderling, much smaller, and Willet, much larger and longer-legged, with blue-grey rather than black bill and legs. The other shorebirds that are remotely similar are the Tattlers, which have more slender bills and paler legs; basic-plumaged Surfbird, which has a shorter, thicker bill, yellow at base, pale legs, and less-distinct face-pattern (but similar pattern on coverts/ scapulars/tertials); Great knot, which is supposed to lack a distinct supercilium, have round black spots on chest and flanks, black upperparts, a longer, more slender bill. .

Loess Hills / Missouri River Valley. The bird was coming from out of the valley. It crossed the wooded ridges of HNA and headed southeast.

The documentation form by Mark Orsag is the earliest and the one that forms the basis of this record. | Elimination of similar species: I considered 5 other species of raptor in total. I eliminated two possibilities (Rough-legged Hawk and Northern Harrier) within seconds of seeing the bird in question. I eliminated two others (Bald Eagle [imm.], and Red-tailed Hawk more or less during the minute or so that I had the bird in view. **** ** I reviewed, in my head, the fine points of the Krider's Red-tailed Hawk for a few seconds after the bird had disappeared from view. The fifth species came to mind just before I started writing this report (the next day). I retroactively eliminated it. In reconstructing my reasoning, I believe: Rough-leg was eliminated due to the unmarked white throat, breast, underwings, and underside. Northern Harrier was eliminated due [sic] the large size and robust shape of the bird, the flight pattern (especially wingbeat), the unstreaked white throat, etc. Immature Swainson's Hawk later eliminated by dark head, white wing patches on primaries, lack of dark flight feathers on underwing, unlikelihood of December sighting. Bald Eagle immature- (whitebelly I-II) was eliminated by the downpushing wingbeat, the colors of the bird's dorsal surface, the lack of a contrast on the dorsal surface between the brown-gray forward part of the wing and the darker flight feathers (a little known good fieldmark for Immature BE), and the confining of the white coloration to the primaries, etc. Red-tailed Hawk-This species, in light of its similar (but smaller) size and variable plumages, posed the greatest problems. The dark upper surface, dark head, pointed wings, and pattern of flight (dihedral in glide posture), as well as the distinct and identical nature of the white markings on the upperwings and the lack of patagial marks, "commas", or other dark markings on the underside, were considered in total and used to rule out the immature light-morph Red-tail and, on reflection, a partial albino Red-tail. Krider's Red-tailed Hawk was the toughest to rule out. Here are my reasons: 1. Krider's heads appear white/light in contrast to the darker (gray or brown) color of the back. This bird's head was not lighter in color (on top) than the back. Back coloring was too dark (brown-reddish) for Krider's-no white mottling seen. Wings were pointed not rounded. No 'headlight' fieldmark [sic] was seen and the 'points of light' fieldmark [sic] was. Dihedral in glide unusual but not impossible for a Red-tail, but the wingbeat (fluid and downpushing rather than centered on the downstroke at the wrist) did not look like a Red-tailed's. | The original documentation form event lasted from 09:00:00/09:01:00.

The documentation form by Rodger Junck is the only one submitted and forms the basis of this record. Other observers include unnamed sister. | Elimination of similar species: Most familiar with red-tails. I have had more than a dozen of them at a time circling my combine during harvest. Have seen them 'displaying' against each other over a rabbit as well. In fact, I see them most days - but they are considerably too small and, except for the Krider's, would be wrong color. I have no info on if Kriders have a white head and white feathery legs | The original documentation form event lasted from 09:30:00 - -09:35:00.

Also larger - Red-tailed Hawk - could not see dark patagial marks. Wingtips were long. Tail was not red - | The original documentation form event lasted from 14:30:00/15:20:00.

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.
