Thayer's may be confused in first year plumage with Kumlien's form of Iceland Gull, but the Thayer's had primaries slightly darker than the mantle (from above), whereas the opposite occurs in Iceland Gull (Lehman). Lehman also notes that some first-year Western Gulls may show translucent primaries from below in certain light, but these observations took place in excellent light at fairly close range. | The original documentation form event lasted from approximately 09:30:00/11:00:00.

The direct size comparison, seen gull being smaller, bill shape and dark color, and lack of white in head eliminates Ring-billed Gull. Mew Gull is eliminated by long dark bill, Ring-billed like jist of bird in flight, and uniform overall color. The long down turned bill and the total improbability of a juvenile Franklin's being in southern Iowa on this date. | The original documentation form event lasted from 10:19:00/10:30:30 on June 4, 1991 and 09:30:00/09:35:00 on June 5, 1991.

Pale Thayer's may be confused with same-aged Iceland Gull, but Iceland typically much paler than this individual. Iceland should also show pale, mottled tertials and tail which are concolor with the upperparts. This bird's tertials and tail were unpatterned (except at the edges of the tertials) and darker than the remainder of the upperparts. Iceland's folded primaries are paler than the remainder of the mantle, not darker as in this bird. Slaty-backed, Glaucous-winged, and Glaucous-winged X Western hybrid Gulls all larger, have more massive bills, less likely in Iowa. | The original documentation form event lasted from 10:15:00/10:40:00.

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.

[...] I picked this bird out because of it's small size compared to the other Herring Gulls present (40). It was smaller than any of the Herring gulls present, but still much larger than any of the numerous Ring-billed gulls. The head appeared more rounded than the Herring gulls and the heavy brown streaking on the nape and neck was more extensive and darker than any Herring present. The bill w/a red gonys mark on the lower mandible was shorter and thinner w/less gonys than the Herrings. They eye iris was dark not yellowish as in all the Herrings present. | The original documentation form event lasted from 10:00:00/10:35:00.

The documentation form by Jeffrey R. Livingston is the only one submitted and forms the basis of this record. Other observers include Joe Breshears. | Elimination of similar species: Upon first seeing the bird and noticing the bill, I thought of an Evening Grossbeak, [sic] but this bird had a dark bill not a yellow-green one. The body was definitely gray not yellowish. When I saw it closer and in better light, I noticed the rust on the head and rump. This eliminated the Evening Grossbeak. [sic] The bird had no crest or prominent eye markings as do the Waxwings. The under tail coverts were gray. The waxwings are rusty. The White-winged Crossbill is lots smaller and has red on the breast and throat. | The original documentation form event lasted from 09:50:00/10:05:00.
