Records Committee review for rare bird sighting of Thayer's Gull at Red Rock Dam, 1991	Administrative records Field notes	Bird watching Ornithology Ornithology--Societies, etc	1991-10-24	1993-07-17	Rare birds documentation form	Records Committee review for a Thayer's Gull at Red Rock Dam in Marion County, IA on October 24, 1991. Includes a record review document with votes and a documentation form submitted to the committee.	Johnson, Ann	Thayer's Gull	Red Rock Dam	Below dam, Red Rock Reservoir, Marion Co., IA	Gravel bar and open river	The documentation form by Ann Johnson is the only one submitted and forms the basis of this record. \| Elimination of similar species: Herring Gull was eliminated by the light and uniform body color, brown as opposed to blackish primaries and tail band, lack of a window from above, and lack of any color to the underside of the primaries. Iceland Gull was eliminated based on the darker secondaries and wide, brown tail band. \| The original documentation form event lasted from 16:50:00/17:15:00.

Records Committee review for rare bird sighting of a Thayer's Gull at Red Rock Reservoir Dam, 1985	Administrative records Clippings (information artifacts) Field notes	Bird watching Ornithology Ornithology--Societies, etc	1985-12-10	1993-09-03	Rare birds documentation form	Records Committee review for a Thayer's Gull at Red Rock Reservoir Dam in Marion County, IA on December 10, 1985. 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

Thayer's Gull	Saylorville Dam	Above and below Saylorville Dam	Open water, rocky shore and ice covered pond.	The documentation form by Joe Schaufenbuel is the only one submitted and forms the basis of this record. \| Elimination of similar species: [...] Nearly the same size as an immature Herring Gull, but neck seemed thinner, head smaller. Bill was same length as a Herring Gull's but was blunter, not as strongly hooked. [...] The primaries were not nearly as dark as immature (1st year) or 2nd year Herring Gulls and was of a much different color than the black color of that species. Primaries and tail were nearly the same color. [...] In flight this bird could be easily picked out from the immature Herring Gulls at considerable distances. Using 7x35 binoculars the beige color of the upper surface of wings and translucent underwing could be detected as far as three-quarters of a mile. There were also three other birds that resembled this particular bird though they appeared darker on the upperparts. However I was unable to get close observations of these birds. The bird I observed closely and documented had one primary feather missing and aided in tracking the bird from day to day.	Iowa Ornithologists' Union \| MS 166	11	3

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.
