The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. Other observers include Tanya Bray. | Elimination of similar species: The body shape, bahavior, [sic] and plumage identify the bird as a phalarope. Bill shape eliminates other phalaropes, which would be even more unlikely on this date. | The original documentation form event lasted from 09:30:00/10:45:00.

The documentation form by Jim Fuller is the only one submitted and forms the basis of this record. | Elimination of similar species: The amount of black and white in the outer primary tips (both upper and underwing) is much less than would be expected in Ring-billed or Herring. Ring-billed is smaller with a dark ring on bill of adult. Although a few Herrings have somewhat bright pink legs, most are a dull pink. An Iceland adult should have a lighter mantle and upperwing, and less gray (not black) on the outer primary tips. | The original documentation form event lasted from 13:50:00/14:15:00.

The documentation form by Randall Pinkston is the only one submitted and forms the basis of this record. | Elimination of similar species: Contrasted with first-winter Herring Gull above. First-winter Iceland typically much paler, especially the uppersurface of the primaries which are paler than the rest of the mantle, and Iceland should show mottling in the tertials and tail band. I suppose I cannot exclude a heavily-pigmented 'Kumlien's' Gull or an Iceland-Thayer's intergrade as described in Kevin Zimmer's Birding article. Both species are apparently highly variable. | The original documentation form event lasted from 10:45:00/11:15:00.

The documentation form by Randall Pinkston is the only one submitted and forms the basis of this record. Other observers include Jim Fuller. | Elimination of similar species: Compared with first-winter Herring Gull above. 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 Barb L. Wilson is the only one submitted and forms the basis of this record. | Elimination of similar species: Similar to most of the other large immature gulls of the world. Mantle too light for Black-backed group. Wingtips, even in their folded condition, too dark for Glaucous, Glaucous-winged, etc. that leaves a whole mess of light-mouthed large gulls with dark wing tips. Description seems to match young Herring Gull (second summer ?) well enough. Eye color would probably be becoming pale in a Herring of this plumage, but perhaps not, + it might not show at the distance. I have trouble eliminating California Gull, but it is even harder to support that species.

Laughing were clearly 20-25% larger, as was bill. A more prominent 'gonys' made the bill appear somewhat more hooked. In flight, the wing tips were black + more extensive than Franklins, both above + below. I looked carefully for any trace of white between tip + rest of wing, as well as for any white on the head, and there was none. The eye ring was broken on the front, less so in the back. The Franklin's had a rounder appearance to the head than did the Laughing. In flight, the Laughing's tail was pure white. | The original documentation form event lasted from 08:05:00/08:35:00.

The documentation letter by Ken Lowder is the only one submitted and forms the basis of this record. Other observers include John Daniel. | Elimination of similar species: It acted differently from the Common Loons. When it dove, it "reared back" its head, as though it were "winding up" for the dive. The Common Loons did not do this. In the Walsh article, this behavior is discussed. On page 26 of his article, Walsh states that "both Pacific and Artic Loons have similar diving motions." I do not believe our bird was a Pacific Loon. I base this judgement on overall body size, bill size, and the distribution of white coloration in the head/neck, waterline, and flank areas. Our bird was essentially similar size-wise to the accompanying Common Loons. The bill was also similar to Common Loon. It was not upturned and this as I would have expected with Red-throated Loon.
