Thompson, Dennis	Laughing Gull	Sandpiper Recreation Area	New Beach (sw of marina) Saylorville Lake Polk Co Ia	Sandy beach.	The documentation form by Dennis Thompson is the only one submitted and forms the basis of this record. \| Elimination of similar species: Franklin's gull - bird had a completely different build. I had the advantage of a direct comparison with ring-billed. This bird was smaller, but still larger than a Franklin's. I would say it was half-way between a Ring-bill + Franklin's in size. White was almost non existent in the wingtips, both at rest + in flight. The most obvious difference was the structure of the bird. As soon as I saw it, I knew it wasn't a Franklin's. The long neck, size, long legs, long bill, + "pot-bellied" look caught my eye immediately. I guess another way to describe it was upright-looking. \| The original documentation form event lasted from 06:30:00/06:35:00.	Iowa Ornithologists' Union \| MS 166	10	18

Potential other observer includes Thomas H. Kent. \| Elimination of similar species: [...] I looked at my field guides + realized that I was not sure if I could distinguish Franklins from Laughing Gulls in their last summer plummage [sic] before becoming adults. I am not sure of the identification. At present I lean toward Laughing due to 1. lack of obvious white on wings 2. Size of dark patches @ wing tips 3. Dark color of mantle 4. The white tail rules out all the younger birds. \| The original documentation form event lasted from approximately 10:00:00/10:05:00.	Iowa Ornithologists' Union \| MS 166	10	18

High Rock Bridge near Dixon, Scott Co.	grassy ditch along county road	The documentation form by Peter C. Petersen is the only one submitted and forms the basis of this record. Other observers include Don Moeller and Walter Zuurdeeg. \| Elimination of similar species: Yellow Rail-no white wing patch. Sora & Virginia Rail-bird much too small, flight weaker than either.

Large, man-made lake - sandy beaches	The documentation form by Robert K. Myers is the only one submitted and forms the basis of this record. Other observers include Eugene Armstrong and Eloise Armstrong. \| Elimination of similar species: The gull was too big and had too large of a bill for herring gull. The checkered back + very contrasty head + upper breast with lower are not consistent with herring. Basically size of bird + its bill eliminated most everything. \| The original documentation form event lasted from 18:30:00/18:45:00.	Iowa Ornithologists' Union \| MS 166	10	21

Other observers include Cal Knight, Bernie Knight, Walter Zuurdeeg, Ann Barker, Mary Lou Petersen, and Gerry White. \| Elimination of similar species: As I was filling my bird feeders I noticed two birds in the silver maple behind the house that at first glance appeared to be house sparrows. I was struck by the neat appearance and greater activity of these particular birds and by the fact that they were not associating with the flock of house sparrows near the bird feeders. Even without binoculars I was able to see the black spots on the birds faces. \| The original documentation form event lasted from 10:00:00 through the afternoon.

Barrow's Goldeneye	DeSoto National Wildlife Refuge	Iowa portion of DeSoto Bend National Wildlife Refuge	water - central portion of large body of water at DeSoto Bend NWR	The documentation form by Andrew S. Fix is the only one submitted and forms the basis of this record. Another observer was Craig Harms. \| Elimination of similar species: Only species for possible confusion is Common Goldeneye, which was readily separable by the lack of dark lateral breast band in Common Goldeneye. Lack of dark back with linear row of white spots parallel to midline in Common Goldeneye and the overall whiter appearance of the Common Goldeneye. The final spot of the Barrow's is supposedly a cresent [sic] however this was not clearly evident in this bird, as the spot it had was suggestive of a cresent [sic] when compared to the nearby Common Goldeneye. Voice and behavior were not helpful in separation in this case. \| The original documentation form event lasted from 11:30:00/12:00:00.	Iowa Ornithologists' Union \| MS 166	8	21

River, Keokuk, Lee Co, Iowa	River rapids.	The documentation form by Robert Cecil is the only one submitted and forms the basis of this record. Another observer includes Doug Reeves. \| Elimination of similar species: First year Herring much more "contrasty"--see above. Kumlien's Iceland Gull...According to Seabirds (Harrison), 1st year Iceland is more pale, tail uniform gray. Overall body coloration is more like 1st year Glaucous--bird I saw was darker than 1st year Glaucous. [...] The important thing about this uniformity that the accompanying first year Herring Gulls had much contrast, showing whitish head, darker wingtips, dark at the tip of the underwings (sometimes), and most obviously, much darker secondaries, creating a dark trailing edge to the wings. Their general color was a darker chocolatey brown. [...] BILL: Pinkish--noticably [sic] smaller that [sic] Herrings. This is pretty subjective, but at about 2/3 of the way across the river at the dam (maybe one third mile) the bill on a Herring can be easily seen through my scope. [...] A very indistinct darkening (wing, upper surface) of the first two or three primaries. The mark had to be looked for to be seen--on the Herring it was much more evident. [...] At some times, the bird showed secondaries that were slightly darker than the rest of the wing. Slightly should be emphasized--at no time was it even close to the darkness of the secondaries of the first year Herring. [...] There was a very slight and indistinct darkening to the first two or three primaries, but this had to be looked for carefully. I have also seen a number of 1st year Herring Gulls that fit this description, but all have a distinct window at base of primaries. \| The original documentation form event occurred at various times during the date range of sightings on the documentation form.
