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.

Another documentation form by Stephen J. Dinsmore was submitted later. Another observer includes Susan Grove. \| Elimination of similar species: I am uncomfortable committing to California Gull given the brief and distant view I had, and my limited past experience with the species. My fear is that this was just a small Herring Gull. Herring can be quite variable in overall size, bill size, and in terms of color and shade of the first-winter plumage. Supposedly 10-15% of first-winter Herrings' can have a "dipped-in-ink" bill in the fall (Harrison 1983 or Grant 1986?). \| The original documentation form event lasted from 12:30:00/15:30:00.
