This bird was quite distinctive in terms of the orange legs, black smudge across the breast, blackness of the upper parts, and white V in the tail. I judged the sex as a female based on size and plumage, and the plumage as alternate based on the distribution of black and the feather wear. More black on the underparts might be expected in fresh spring plumage. | The original documentation form event lasted from 09:10:00/09:40:00 and 16:30:00/16:40:00.

[...] 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. .

The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. Other observers include Scott Rolfes. | Elimination of similar species: The color and wing crescent eliminates all larids except skuas and Pomarine and Long-tailed jaegers. Skuas are easily eliminated by their larger size, heavier bill, and more prominent white patches on the wings. Long-tailed Jaeger is eliminated by the presence of a white crescent on the upper surface of the wing. Pomarine Jaeger can be eliminated by its larger, heavier body size, more prominent white crescent on the wing, presence of white greater underprimary coverts, larger-headed appearance, heavier bill, and general lack of rufous color on the body. | The original documentation form event lasted from 16:22:00/16:51:00.

The documentation form by Ann Johnson and Jim Bangma is the earliest and the one that forms the basis of this record. | Elimination of similar species: The powerful direct flight, the longish tail, and the rounded broad wings identified this bird as an accipter. Bangma's first comment was that the width of the wings reminded him of Hook-billed Kites in So. Texas, a dramatic characteristic that allows experienced hawk watchers to identify Northern Goshawk from a distance - literally a stovepipe with broad wings. Buteos have a much shorter tail that gives them an entirely different look and feel. A gray adult male Northern Harrier would look white below and have longer wings proportionate to the body. Although we were unable to see the bird at an angle to see every characteristic of this species, other accipters would have been rufous or brown from below. Although this is certainly a late date for this species, Northern Goshawk has been seen in the winter in and near this location. In breeding areas it feeds on grouse. We speculated on the reintroduction of Ruffed Grouse in this area and what effect it might have on late migration and even potential breeding. | The original documentation form event lasted from 13:45:00/13:46:00.
