The documentation form by Michael Newlon is the only one submitted and forms the basis of this record. Other observers include Carol S. Newlon. | Elimination of similar species: proportions, uniformly pale primaries would rule out herring; size/build rules out imm. glaucous. Bill much less heavy than imm. glaucous-winged. Remaining question is whether this bird is (over) a Thayer's Gull or a Kumlien's gull, presently considered separate species but widely suspected of being conspecific. Thayer's is extremely variable, and the limits of its variability are not well known, especially for imm. plumages. [Dwight says of his series of ad. thayeri, 'no two are alike'. It seems probable that there is clinal variation from west to east (thayeri - kumliesi [sic] - nominate glaucoides) and even possible that thayeri interbreeds with argenlatus at the western end of its range.] In addition several plumage descriptions in the literature may be assigned to birds of [illegible] age. Be that as it may: L. glaucoides glaucoides is supposed to have pale warm-brown primaries as a 1-W & paler, nearly whitish areas as a 2-W (though photos in grant's [sic] book show one 2-W with pale-brown primaries concolor with coverts). L. glaucoides kumlieni (in Dwight's plates) is assigned v. pale primaries as a 1-W, with slightly darker outer webs; would look uniform pale grey at any distance. His 2-W has darker primaries, again with slightly darker outer webs [I suspect these assignments should be reversed.] L. thayeri in published description is supposed to have darker primaries still, though not so dark as those of imm. Herring gulls, and lacking contrast with mantle. However some west coast thayeri-type gulls are very pale - though their back color is grey-brown rather than the warmer pale tan of L. glaucoides. (It is possible that these are really kumlieni but little data exists.) It is the similarity of the Cone Marsh Bird to one I photographed in Cal. that convinced me to classify it as thayeri - though kumleni cannot be unequivocally ruled out | The original documentation form event lasted from 11:10:00/12:30:00.

The documentation form by Ray Cummins is the only one submitted and forms the basis of this record. Other observers include Ann Johnson. | Elimination of similar species: see above. [...] 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 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.

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 wingtip pattern is what caught my attention. There was much less darkening to the outer primaries than on accompanying gulls. [...] When viewed fro [sic] underneath, the wingtips of the subject bird were white to the tips, with the exception of very narrow black tips at the tips of the primaries. This was very different from the adult Herring/Ring-bills which had substantial black towards the end of the underwings. | The original documentation form event lasted from 10:30:00/10:45:00.

The documentation form by Scott Gritters is the only one submitted and forms the basis of this record. Other observers include Kevin Timmer. | Elimination of similar species: Upon sighting of the bird in the tree we eliminated hawks by large size and black over whole body. At first his head appeared to be black headed - so I thought it was an immature bald eagle. This also cleared it from being a Turkey Vulture. Finally the bird turned its head toward us as it was getting 'nervous' - this revealed a golden crown. | The original documentation form event lasted from 12:00:00/12:05:00 approximately.
