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).

Dinsmore is the only one submitted and forms the basis of this record. Other observers include Susan Grove, Eugene Armstrong, and Eloise Armstrong. \| Elimination of similar species: On the basis of size and general plumage characters, this species could only be confused with Ring-billed Gull, hundreds of which were available for direct comparison. The combination of slightly smaller size, distinct head shape, bill color and shape, dark eye, and slightly darker mantle and upperwings are sufficient to eliminate Ring-billed Gull. \| The original documentation form event lasted from 15:42:00/16:53:00.

Includes a record review document with votes, an article in Iowa Bird Life, and three documentations submitted to the committee.	Johnson, Ann	Mew Gull	Whitebreast Recreation Area	Whitebreast Recreation Area, Red Rock Reservoir, Marion Co., IA	Sandy area at edge of open water	The documentation form by Ann Johnson forms the basis of this record. Other documentation forms by Russ Widner and Jim Fuller were submitted. Other observers include Dick Tetrault and Roy Godwin. \| Elimination of similar species: Size eliminated any gull larger than a Ring-billed. Although structurally the bird more closely represented one of the larger hooded gulls, they were eliminated by the lack of any hood or auricular spot. Furthermore, most hooded gulls with a tail band would also show a strong carpal bar. Laughing Gull could be eliminated by the more diminuative [sic] bill and leg color. Although some individuals seem to carry a vestige of their more motley juvenile plumage into first winter, Ring-billed Gull was eliminated by size, head and bill structure, and clear-cut as opposed to more diffuse tail band. I originally identified this bird as a Mew Gull based on my experience studying structural differences between Ring-billed and Mew gulls on the west coast. I have never seen a first-year Mew Gull, however. In researching the Mew on my return home, I concluded that the bird in question was not dark enough, nor brown enough, to be of the west coast sub-species. By virtue of its strong similarity to a Ring-billed Gull, this bird was most likely the European sub-species known as the Common Gull. Although according to Grant the bill description comes closer to L.c. brachyrhynchus, I assume that this bird's bill coloration was still changing from juvenile plumage. Apparently the Common Gull appears on occasion on the east coast and is therefore probably as likely a vagrant to Iowa as is the western form. \| The original documentation form event lasted from 10:30:00/10:40:00.

The documentation form by Jim Fuller is the only one submitted and forms the basis of this record. Other observers include John McClure, Chris Edwards, and Jonnie Ellsworth. \| Elimination of similar species: All other dark mantled gulls have a larger size.

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.	Iowa Ornithologists' Union \| MS 166	34	35

[...] An adult gull in between the size of adjacent Ring-billed and Herring Gulls. It was noticeable larger than the Ring-bills; not too much smaller than the Herrings.
