Fuller, James L	Great Black-backed Gull	Ben Butterworth Parkway	Mississippi River between Bettendorf, Iowa and Moline, Illinois (Scott Co.).		The documentation form by Jim Fuller is the only one submitted and forms the basis of this record. \| Elimination of similar species: [...] In the middle of the group was a gull that was darker than any of the other birds, even the immature Herring Gulls. [...] In general size, this bird appeared almost twice the size of the Ring-billed Gulls, and considerably larger than the Herring Gulls, maybe 25%. It also had a massive bill compared to either of those species.

Includes a record review document with votes, a photograph, and a documentation form submitted to the committee.	Johnson, Ann	Laughing Gull	Saylorville Dam	Below Saylorville Dam, Polk County, IA	Fast moving river with many small fish	The documentation form by Ann Johnson is the only one submitted and forms the basis of this record. \| Elimination of similar species: The body and bill structure eliminated all but hooded gulls and the brown plumage indicated a first year bird. Size close to Ring-billed, in addition to plumage already described, eliminated some of the smaller hooded gulls. The most likely candidate for confusion would be the Franklin's Gull. Juvenile Franklin's shows a hooded pattern early in development rather than a brown wash on the head. Franklin's tail band would also be incomplete with white feathers showing on the outer edge. It would also show fewer dark primaries, with the inner flight feathers more approximating the mantle and inner wing color. No other small gull has this characteristic. \| The original documentation form event lasted from 11:45:00/12:10:00 and 15:30:00/14:00:00 [sic].	Iowa Ornithologists' Union \| MS 166	10	18

Fuller, James L	Lesser Black-backed Gull	Lake MacBride Beach	Swim Beach of Lake MacBride State Park (Johnson County).		The documentation form by Jim Fuller is the only one submitted and forms the basis of this record. \| Elimination of similar species: All of the other larger gulls that are dark-mantled are larger than Lesser Black-backed. In addition, all those adult birds have pink legs, except Yellow-footed Gull, which has never been seen away from southern California and is larger than Herring Gull. \| The original documentation form event lasted from 15:59:00/16:03:00.

Fuller, James L	Iceland Gull	Lake MacBride	Short rock jetty from south shore of south arm of Lake MacBride (Johnson County).		The documentation form by Jim Fuller is the only one submitted and forms the basis of this record. \| Elimination of similar species: First year Thayer's Gull is generally darker, with noticably [sic] darker tail and primaries. First year Glaucous Gull is larger with a two-toned bill. \| The original documentation form event lasted from 16:39:00/16:42:00.	Iowa Ornithologists' Union \| MS 166	11	4
Records Committee review for rare bird sighting of Iceland Gull at Credit Island, 1993	Administrative records Field notes	Bird watching Ornithology Ornithology--Societies, etc	1993-02-14	1995-07-08	Rare birds documentation form	Records Committee review for an Iceland Gull at Credit Island in Scott County, IA on February 14, 1993. Includes a record review document with votes and a documentation form submitted to the committee.	Johnson, Ann	Iceland Gull	Credit Island	Credit Island, Davenport, Scott County, IA	Frozen lagoon with small amount of open water	The documentation form by Ann Johnson is the only one submitted and forms the basis of this record. \| Elimination of similar species: Although the duskiness on the face had somewhat of a "hooded" effect, any of the hooded gulls could be eliminated by the bill structure. The pale primaries eliminated all but the white-winged gulls - Glaucous, Iceland, and possibly Thayer's. Glaucous can be eliminated by size and bill color. Thayer's was eliminated because of: 1) overall gray-white appearance; 2) the lack of any secondary bar; and 3) the checkered tertials. Problems with the record are the duskiness on the face and the narrow dark edging to the outer primaries from below. These two characteristics may well indicate an Iceland/Thayer's intergrade. \| The original documentation form event lasted from 13:15:00/13:40:00.	Iowa Ornithologists' Union \| MS 166	11	4
Records Committee review for rare bird sighting of Iceland Gull at Centennial Bridge at Davenport, 1993	Administrative records Field notes	Bird watching Ornithology Ornithology--Societies, etc	1993-02-07	1995-07-08	Rare birds documentation form	Records Committee review for an Iceland Gull at Centennial Bridge at Davenport in Scott County, IA on February 7, 1993.

Fuller, James L	Iceland Gull	Centennial Bridge	Below Centennial Bridge, Mississippi River, Scott County.		The documentation form by Jim Fuller is the only one submitted and forms the basis of this record. Another observer includes Jim Scheib. \| Elimination of similar species: This bird was much too small for a Glaucous Gull, and the generally whiter cast and two-toned bill would suggest a second-winter, compared to first-winter Iceland. \| The original documentation form event lasted from 14:55:00/15:00:00.	Iowa Ornithologists' Union \| MS 166	11	4

Includes a record review document with votes and a documentation form submitted to the committee.	Cummins, Raymond L.	Iceland Gull	Rathbun Dam	Lake Rathbun Dam Appanoose Co.	The Iceland Gull was sighted on the ice above the dam feeding on a dead Canada goose. It was very protective of the food source chasing Crows away.	The documentation form by Ray Cummins is the only one submitted and forms the basis of this record. Other observers include Mary Montgomery and Dot Cornett. \| Elimination of similar species: Thayer's Gull was eliminated because there was no dark in the primaries, no dark secondary band, and bill was not all dark. A first-winter Glaucous would have the coloration but there is no way this gulls bill or body size was big enough tobe [sic] a Gloucous [sic] Gull. \| The original documentation form event lasted from 09:45:00/10:30:00.

Pinkston, Randall, 1956-	California Gull	Saylorville Dam	Saylorville Reservoir dam, Polk County, Iowa		The documentation form by Randy Pinkston is the earliest and the one that forms the basis of this record. Another documentation form by Stephen J. Dinsmore was submitted later. Another observer includes Susan Grove. \| Elimination of similar species: I am uncomfortable committing to California Gull given the brief and distant view I had, and my limited past experience with the species. My fear is that this was just a small Herring Gull. Herring can be quite variable in overall size, bill size, and in terms of color and shade of the first-winter plumage. Supposedly 10-15% of first-winter Herrings' can have a "dipped-in-ink" bill in the fall (Harrison 1983 or Grant 1986?). \| The original documentation form event lasted from 12:30:00/15:30:00.
