Includes a record review document with votes, an article in Iowa Bird Life, and six documentation forms submitted to the committee.	Bendorf, Carl J.	Thayer's Gull	Red Rock Dam	Red Rock Res. Tailwater		The documentation form by Carl J. Bendorf forms the basis of this record. Other documentation forms by Thomas H. Kent, Francis L. Moore, Bob Myers, Beth Proescholdt and Mark Proescholdt, and Dennis Thompson were submitted. Other observers include Joe Schaufenbuel, Darwin Koenig, Steve Dinsmore, Eugene Armstrong, Eloise Armstrong, and many unidentified observers. \| Elimination of similar species: Thayer's Gull is a difficult bird to identify. In researching this problem, I have found several helpful sources in addition to the standard field guides and I have tried to understand what it takes to know a Thayer's Gull when you see one. Nearly every reference makes it clear that Thayer's cannot be identified on the basis of one or two positive field marks. It takes a combination of characters to come to a conclusion of any certainty. In discussing this particular observation, I will examine each of the fieldmarks and compare and contrast to similar species with liberal reference to the literature, especially Lehman (1980). The most likely similar gulls in this case are 1st winter Herring and 1st winter Iceland (Kumlien's). The Kumlien's form is the darker form of the Iceland Gull and is the form that breeds in the Baffin Island area and winters mainly on the Atlantic coast. Lehman's article deals mainly with Kumlien's. Several similarly sized and possible but unlikely candidates can be eliminated rather quickly. A 1st winter California should not have an all dark bill and would show much darkening in the primaries in flight. Lesser Black-backed Gull could be about the right size, but in flight a 1st winter bird should show darker primary and secondary coverts, more extensively dark primaries, even compared to Herring Gull. A 1st summer Slaty-backed Gull is also light uniform brown with an all dark bill, but it should exhibit extensive darkening in the primaries on the upper wing. A 1st winter Glaucous-winged Gull would be very similar to Thayer's but should be larger, with a larger bill, and less mottling to the body color. Except for the first two, one would probably not consider the likelihood of their occurrence in Iowa to be very great. One hybrid, Glaucous-winged X Western, might be similar but should have a quite heavy bill. [...] Summary: Of the most likely similar species, 1st winter Herring Gull and 1st winter Kumlien's Iceland Gull, each is eliminated by one or more of the features discussed above. The wing pattern is especially damaging to the possibility of Herring, along with the bill shape and size. Iceland is ruled out by the presence of the noticeable tail band and by the darker secondaries on the upper wing. To identify a Thayer's Gull, one must see a combination of field marks. I feel that the bird I saw at Red Rock is consistent on every point.\| The original documentation form event lasted from 14:15:00/14:45:00.	Iowa Ornithologists' Union \| MS 166	11	3

Other observers include Chris Pilliod, Jim Sandrock, Cal Knight, Jane Fuller, Charles Fuller, and James Huntington. \| Elimination of similar species: The only species I could not eliminate on the basis of field marks observed was Yellow-footed, which according to Tom Kent (telephone conversation) is not a known vagrant. More objectively, the Yellow-footed is supposed to be larger than a Herring Gull. As stated above, this bird was about the size of a Herring Gull, or perhaps a little smaller. I don't feel it was larger than a Herring Gull. Seabirds (Harrison) warns of possible confusion with dark race Herring Gull. I have not heard of this race occuring [sic] in Iowa. In any event, the foot coloring was incorrect for Herring Gull, which has pink legs in contrast to this bird's yellow legs. \| The original documentation form event occurred at various times.

White, Gerald	Townsend's Warbler	Wildcat Den State Park	[...] At Wild Cat Den State Park in a small area of bottom land of deciduous woods on May 12, 1988 at 7:20 AM, for aproximatly [sic] 45 seconds.		The documentation form by Gerald White is the only one submitted and forms the basis of this record. \| Elimination of similar species: [...] When the first look at the head I thought of a possible Blackburnian but when I saw the neck I knew I had a new bird for myself. The most striking features being the head and throat markings. [...] I then checked the rest of the birds listed and made the summation that I had seen the Townsend's. That evening when I returned from work I checked my Golden, Peterson, N.G.S. and Audubon Master Guide for their accounts of the Townsend's and similar species. I eliminated the following; Hermit Warbler - no cheek patch: Blackburnian - dosn't [sic] have a black throat: Black-throated Green - has solid back color and cheek patch not as bold, no black cap. Of the references mentioned, the N.G.S. has the most accurate illustration of the birds head but I can't verify that the bird I saw did or didn't have yellow under the eye. \| The original documentation form event lasted from approximately 07:20:00/07:20:45.
