Ernzen, Peter	Long-billed Curlew	Black Hawk Lake	dredge pond area southeast of Blackhawk Lake in Sac Co.		The documentation form by Peter Ernzen is the only one submitted and forms the basis of this record. Other observers include Joshua Ernzen. \| Elimination of similar species: [...] Whimbrel was eliminated by size, color and bill size. The whimbrel should have been slightly smaller to about the same size as the marbled godwits. The brown body and cinnamon wing linings did not fit whimbrel either. The bill size is variable with shorebirds, however the great length of the bill was more suggestive of the long billed curlew. The call heard does not fit the description for whimbrel in my National Geographics [sic] Field guide to Birds of North America. Three outside possibilities the far Eastern curlew, Eurasian curlew, and bristle thighed curlew were eliminated as well. The far Eastern curlew size is about the same as that of the marbled godwit. The bird also has white wing linings with dark barring. The barring would be hard to see, however the lighter color would be distinguishable. The Eurasion [sic] curlew was eliminated because this bird would have a white rump, and white wing linings. The bird I saw in flight turned and twisted. I did not notice any white markings on the rump. The bristle thighed curlew is much more similar to the smaller whimbrel and would be eliminated by small size, shorter bill and call - "chu-a-wut". \| The original documentation form event lasted from 19:50:00/20:00:00.

The documentation form by Babs & Loren Padelford is the only one submitted and forms the basis of this record. \| Elimination of similar species: At rest, the bird had a very slender and streamlined appearance, not stocky like that of a Franklin's Gull. The head had no trace of a dark hood. The head was the same color as the rest of the body except for lighter areas around bill, on forehead and top of the head. The bill seemed longer and more curved than a Franklin's, but difficult to say with no Franklin's for comparison. \| The original documentation form event lasted from 10:15:00/11:05:00.

Other observers include May Lou Petersen and Dan Dorrance. \| Elimination of similar species: Franklin's Gull - larger, much heavier bill, wider tail band, this bird with much more extensive area of black on primaries.

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

Includes a record review document with votes, a photocopy of a photo, and a documentation form submitted to the committee.	Dinsmore, Stephen J.	Laughing Gull	Oak Grove Recreation Area	Oak Grove Beach, Saylorville Reservoir, Polk Co., IA		The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. Other observers include Eugene Armstrong and Eloise Armstrong. \| Elimination of similar species: On the basis of the dark hood, size, and dark gray mantle, all gulls except for Laughing and Franklin's gulls can be removed from consideration. I will admit that I was skeptical that a Laughing Gull could show up in Iowa on such an early spring date; most interior records are from May-June. But, given the evidence, I am convinced that this bird was indeed a Laughing Gull. The size of this bird, nearly that of a ring-billed gull, favors Laughing Gull. The bill shape and size, length of the legs, wing pattern, and extent of the eye crescents also favor Laughing Gull. An adult Franklin's Gull can be eliminated by the lack of a white bar separating the gray inner wing from the black wingtip. One year-old Franklin's Gulls, however, may show a wing pattern like that of this bird. But, according to Kaufman (1990), such a Franklin's Gull should show some white flecks on the hood, and would be most likely encountered in late spring and summer. \| The original documentation form event lasted from 10:48:00/11:34:00 and 12:26:00/13:20:00.

Includes a record review document with votes and two documentation forms submitted to the committee.	Bray, Tanya	Laughing Gull	Lake Manawa	Lake Manawa, Pottawattamie County		The documentation form by Tanya Bray forms the basis of this record. Another documentation form by Ross Silcock was submitted. Other observers include Babs and Loren Padelford. \| Elimination of similar species: This bird differed from Franklin's Gull in the following ways: 1. Less extensive black on head. Eye coverts were not immediately noticable [sic] due to white cheek area. 2. Longer legs, more upright posture, and generally a very long, slender bird. 3. In flight, the bird had long slender wings with completely dark primaries; no white dividing the tips of the outer primaries from the rest of wing, and no white tips to outer primaries. Underside of primaries as described above. 4. Bill was long, curved and slightly swollen and hooked at tip. \| The original documentation form event lasted from around 07:35:00/07:36:00, 08:45:00, 12:15:00, and 18:30:00.

Hollis, Richard Jule	Laughing Gull	Hawkeye Wildlife Management Area	Hawkeye Wildlife Area, Johnson Co, IA	marshy backwaters of reservoir	The documentation form by Richard Hollis is the only one submitted and forms the basis of this record. 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

Jaegers	Spirit Lake	Spirit L., Dickinson Co., IA	large lake	The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. Other observers include James J. Dinsmore. \| Elimination of similar species: The combination of size, dark coloration, and white in the primary shafts eliminated the possibility of a juvenile gull. Despite the great distance and lack of a good view of the wing pattern, I believe the bird was a Pomarine Jaeger. \| The original documentation form event lasted from 13:45:00/14:43:00.
