Records Committee review for rare bird sighting of Thayer's Gull at Coralville Dam, 1981	Administrative records Correspondence Field notes	Bird watching Ornithology Ornithology--Societies, etc	1981-11-08	1993-08-26	Rare birds documentation form	Records Committee review for three Thayer's Gulls at Coralville Dam in Johnson County, IA on November 8, 1981. Includes a record review document with votes, correspondence and commentary about the sighting, summary of the review, and a documentation form submitted to the committee.	Moore, Francis L.	Thayer's Gull	Coralville Dam	Coralville Reservoir	Open wate [sic] near small sandy beach near the Dam area, Johnson County	The documentation form by Francis L. Moore is the only one submitted and forms the basis of this record. Other observers include Russell Hays, Tom Kent, Tom Shires, Tom Staudt, and many unidentified other observers. \| Elimination of similar species: Ring-billed Gull and Herring Gull, see above. The Ring-billed Gulls were seen in direct contrast to these three birds and were definitely much smaller birds. The Herring Gulls (first year birds) that I have seen have more of a contrast between the rump and back and upper wing surfaces and none that I remember showed the whitish trailing edge on the tail. [...] The three birds seen were about the size of Herring Gulls in typical first year plumage. They were obviously large gulls of the genus Larus with a noticeably larger size than the Ring-billed Gulls and one Bonaparte's Gull that were next to the three larger birds. [...] There were no Herring Gulls nearby with which to make a comparison of size and coloration. The bills of all three gulls were black did not seem as heavy or bulky as the bill of a Herring Gull. \| The original documentation form event lasted from 08:10:00/09:30:00.

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

Larger than Ring-billed Gulls- flock of 14 adjacent. [...] Headmuch [sic] smaller relative to body than in the Herring Gull- also flatter-appearing. [...] 1. Bill was black (or very dark); this , combined with the rather pale underparts relative to the rest of the (also rather pale) plumage tends to rule out a first year Herring Gull. 2. Bill and head size and shape were not as heavy-appearing as in Herring Gull. Direct comparison with adjacent adult Herring Gull was very useful in deciding this. [...] 5. Size and pinker legs than Herring Gull are not sure characters, but lend support to identification as Thayer's Gull.	Iowa Ornithologists' Union \| MS 166	11	3

Other observers include Tom Shires, James Kovanda, Sandra Kovanda, Tanya Bray, Babs Padelford, Loren Padelford, B.J. Rose, and four unidentified other observers. \| Elimination of similar species: The above description separates by direct comparison first-year Thayer's and Herring Gulls, the most similar species present. Thayer's may be confused in first year plumage with Kumlien's form of Iceland Gull, but the Thayer's had primaries slightly darker than the mantle (from above), whereas the opposite occurs in Iceland Gull (Lehman). Lehman also notes that some first-year Western Gulls may show translucent primaries from below in certain light, but these observations took place in excellent light at fairly close range. \| The original documentation form event lasted from approximately 09:30:00/11:00:00.

Kent is the only one submitted and forms the basis of this record. Other observers include Dick Tetrault. \| Elimination of similar species: The size and shape in comparison with Baird's Sandpiper establish this bird as a peep. The black legs, gray color, and lack of bib exclude Least Sandpiper (several of which were seen earlier). The distinction from Semipalmated Sandpiper is based on the bill and apparent molt to basic plumage. Five minutes earlier I had seen two Semipalmated Sandpipers running on the other side of the area; they had short straight bills and had all feathers of the upper parts edged with buff (juvenile plumage). I had seen a number of Semipalmated Sandpipers with longer and slightly drooped bills this fall, but none approached the length, thinness, and droop seen on the current bird. According to Kenn Kaufman's Advanced Birding, Semipalmated Sandpipers wear their juvenile plumage until they reach wintering grounds, and juvenile Western Sandpipers gradually molt from juvenile to basic plumage from August to October with some retaining rusty scapulars. I assume, based on date, that this bird was probably a first-year bird, and that it had either completely molted to basic plumage or had some rusty scapulars that I did not see. I did not consider any of the Eurasian stints, which would be exceeding unlikely and have bills more like a semipalmated or have yellow legs. \| The original documentation form event lasted from 10:15:00/10:20:00.

Johnson, Ann	Western Sandpiper	Big Creek Lake	Big Creek Wildlife Area, Polk Co., IA	Mudflats from low water on freshwater lake	The documentation form by Ann Johnson is only one submitted and forms the basis of this record. Other observers include Mike Thomas. \| Elimination of similar species: Although I understand the difficulty in identification of fall western sandpipers, the Baird's and white-rumped were eliminated because of wing length. The least sandpiper was eliminated by leg color and bill shape/size. The most difficult elimination was that of the semipalmateds, especially since other semipals were present in the area. After careful observation and comparison, however, the prototypical western sandpiper bill was too obvious to make the bird into a semipalmated. The bill was enough longer and had an obvious droop. The others in the area had varying bill sizes but none had the general shape of this bird. Consequently, I believe this was a late date western sandpiper. \| The original documentation form event lasted from approximately 15:00:00/15:10:00.	Iowa Ornithologists' Union \| MS 166	10	3
