Records Committee review for rare bird sighting of Thayer's Gull at Lake Manawa, 1981	Administrative records Correspondence Field notes	Bird watching Ornithology Ornithology--Societies, etc	1981-12-05	1993-08-26	Rare birds documentation form	Records Committee review for a Thayer's Gull at Lake Manawa in Pottawattamie County, IA on December 5, 1981. Includes a record review document with votes, correspondence and commentary about the sighting, and a documentation form submitted to the committee.	Silcock, W. Ross	Thayer's Gull	Lake Manawa	Lake Manawa		The documentation form by W. Ross Silcock is the only one submitted and forms the basis of this record. \| Elimination of similar species: [...] Smaller than adult Herring Gull (winter plumage, red spot end of lower mandible) beside it, legs a little pinker. 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

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.

Kent is the only one submitted and forms the basis of this record. Other observers include Carl Bendorf, Mike Newlon, and many unidentified other observers. \| Elimination of similar species: Photographs taken at the first encounter with a Celestron 750 mm lens demonstrate the size difference, the bill and head shape difference, the lighter overall color, and the window in the wing. An adult Herring was in the photo with the Thayer's on 7 Nov and imm Herring were photographed on 10 Nov for comparison. \| The original documentation form event lasted from 09:25:00/09:50:00 and 11:00:00/11:20:00 on November 7, 1981 and 07:30:00/08:30:00 on November 8, 1981.

Includes a record review document with votes, correspondence and comments about the sighting, an article in Iowa Bird Life, and four documentation forms submitted to the committee.	Silcock, W. Ross	Thayer's Gull	Lake Manawa	Lake Manawa, Pottawattamie County, Iowa.		The documentation form by Ross Silcock is the earliest and the one that forms the basis of this record. Other documentation forms by Thomas H. Kent, Peter C. Petersen, and Robert K. Myers were submitted later. 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.

Records Committee review for rare bird sighting of Western Sandpiper at Babcock Access at Coralville Reservoir, 1990	Administrative records Field notes	Bird watching Ornithology Ornithology--Societies, etc	1990-10-13	1993-07-17	Rare birds documentation form	Records Committee review of a Western Sandpiper at Babcock Access at Coralville Reservoir in Johnson County, IA on October 13, 1990. Includes a record review document with votes and a documentation form submitted to the committee.	Kent, Thomas H. (Thomas Hugh), 1934-	Western Sandpiper	Babcock Access	Babcock Access, Coralville Res., Johnson Co. Iowa.	mud flats with shallow pools	The documentation form by Thomas H. 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.

Includes a record review document with votes, correspondence about the sighting by Guy McCaskie, Kim Eckert, and Bruce Peterjohn, and a documentation form submitted to the committee.	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

Other observers include Andy Fix. \| Elimination of similar species: see above [...] The bird was roughly 25% smaller than a Pectoral Sandpiper. [...] Note that we saw a single Semipalmated Sandpiper in the same flock of shorebirds. The Semipalmated Sandpiper had a shorter, thicker bill, more of a brown wash on the breast, and frequented the edge of the mudflat rather than wading in the water. \| The original documentation form event lasted from 15:30:00/16:45:00.
