Records Committee review for rare bird sighting of Thayer's Gull at Red Rock Dam, 1991	Administrative records Field notes	Bird watching Ornithology Ornithology--Societies, etc	1991-11-25	1993-07-17	Rare birds documentation form	Records Committee review for a Thayer's Gull at Red Rock Dam in Marion County, IA on November 25, 1991. Includes a record review document with votes and two documentation forms submitted to the committee.	Johnson, Ann	Thayer's Gull	Red Rock Dam	Below dam, Red Rock Reservoir, Marion Co., IA	Gravel bar and open river	The documentation form by Ann Johnson forms the basis of this record. Another documentation form by Thomas H. Kent was submitted. Other observers include Jim Fuller, Dick Tetrault, and Tim Schantz. \| Elimination of similar species: Herring Gull was eliminated by the light and uniform body color, pale gray primaries, secondaries and tailband, lack of a window from above, and lack of any color to the underside of the primaries. The bird certainly had the overall coloration of a first year Iceland Gull. However, Iceland Gull was eliminated based on the darker secondaries, complete gray tail band, and the darker webs to the outer primaries from above. \| The original documentation form event lasted from 16:10:00/16:50:00 on November 25, 1991 and 13:50:00/14:05:00 on November 28, 1991.

(Thomas Hugh), 1934-	Lesser Black-backed Gull	Coralville Lake	Coralville Reservoir, Johnson Co., IA.	Reservoir mostly ice-covered. Gulls around small patch of open water.	The documentation form by Thomas H. Kent is the only one submitted and forms the basis of this record. Jim Fuller was another observer. \| Elimination of similar species: The size, wing and mantle color and yellow legs exclude other species, except perhaps for the most unlikely Yellow-footed Gull, which should be larger. \| The original documentation form event lasted from 08:45:00/09:00:00.

That bird has never been seen away from that area, and should be noticeably larger than a Lesser black backed gull. The European race of the Herring gull has yellow legs, and one has been seen on the east coast the past two winters. That bird should be larger, and does not have a dark mantle. \| The original documentation form event lasted from 14:03:00/14:27:00.	Iowa Ornithologists' Union \| MS 166	11	5

Includes a record review document with votes, an article in Iowa Bird Life, and two documentation forms submitted to the committee.	Kent, Thomas H. (Thomas Hugh), 1934-	Iceland Gull	Lock and Dam 14	Lock and Dam 14, Scott Co., IA	Mississippi River	The documentation form by Thomas H. Kent is the earliest and the one that forms the basis of this record. Another documentation form by Jim Fuller was submitted later. Other observers include Pete Wickham, John Daniel, Chuck Fuller, Bill Dawes, and John Rutenbeck. \| Elimination of similar species: At first I thought the bird might be a Glaucous Gull, but the all black bill quickly excluded that possibility. Later I confirmed that the bird was smaller than Herrings and had a bill that was too small and too short for a Glaucous. I believe that the tail band also argues against Glaucous. I next considered Thayer's Gull, but decided that the tail band was not extensive enough, that there was no secondary bar, that the wing tips were too light (both in flight and on the standing bird), and that the tertials were not dark enough on the standing bird. All of the findings were a good fit for first-winter Iceland Gull. \| The original documentation form event lasted from 13:15:00/13:35:00 on December 31, 1991 and 08:55:00/10:20:00 on January 1, 1992.

Other observers include Dawn DeVore, Dick Tetrault, Jim Scheib, Beth Brown, Michael Porter, Eugene Armstrong, Eloise Armstrong, and many unidentified observers. \| Elimination of similar species: [...] Iowa Birds mentions that there is a problem separating Iceland with Thayers. If there was any problem with this bird being anything it was a Glaucous Gull of the same age. However the bird was smaller than the Herring Gulls that were on the roost. Long wings will rule out the rare small race of Glaucous Gull. There are not to [sic] many birds that have primaries lighter than the mantle in the sitting bird.

Fuller, James L	Thayer's Gull	Red Rock Dam	Below Red Rock Dam- Marion County	River	The documentation form by Jim Fuller is the only one submitted and forms the basis of this record. Other observers include Ann Johnson, Chuck Fuller, and Jane Fuller. \| Elimination of similar species: Herring Gull (first winter) compared above. [...] I first saw this bird flying, and the underwing was translucent throughout the primaries to the end of the wing (Herring Gull had dark outer primaries, although most also had a lighter window type area medial to this dark area). The bird was about the same size or a little smaller than the Herrings. The upperwing in flight was much lighter in the primaries than the first winter herrings. [...] It had a more rounded head than the herrings. [...] It's color was more uniform than the herrings and also lighter- a brownish color. There was a dark smudge around the eye. The feather edging (whitish) provided more contrast with the brown on the back than in the herrings, and the folded tail was brownish, not black. When in flight the tail band was brownish not blackish like the herrings. \| The original documentation form event lasted from 13:15:00/13:45:00.	Iowa Ornithologists' Union \| MS 166	11	3

Includes a record review document with votes, two articles in Iowa Bird Life, and five documentation forms submitted to the committee.	Kent, Thomas H. (Thomas Hugh), 1934-	California Gull	Babcock Access	Babcock Access, Coralville Reservoir, Johnson County, Iowa	shallow, open area of reservoir	The documentation form by Thomas H. Kent is the earliest and the one that forms the basis of this record. Other documentation forms by Jim Fuller, Randy Pinkston, Carol Thompson, and Carl J. Bendorf were submitted later. Other observers include Timothy Dwyer, John Cordell, James Huntington, Cal Knight, Bernie Knight, and Rick Hollis. \| Elimination of similar species: First-year Ring-billed Gulls were all in first winter plumage with gray mantle and were much lighter overall. The only other species considered is juvenile Herring Gull. The size is small for Herring Gull. The elongated appearance and short legs fit California Gull. Most young Herrings that I see in early fall have mostly dark bills that are larger than that of this bird. The double inner wing bar and lighter tertial tips fit California Gull. The overall relatively uniform and relatively light brown color without windows in the inner primaries also made this bird look different from Herring Gull. \| The original documentation form event lasted from 15:15:00/16:55:00 on October 27, 1990 and from 19:10:00/22:30:00 and 15:00:00/16:00:00 on October 28, 1990.

California Gull	Oak Grove Recreation Area	[...] Oak Grove Beach Recreation Area at Saylorville Reservoir, Polk County.		The article by Stephen J. Dinsmore forms the basis of this record. \| Elimination of similar species: [...]The bird was similar in size to the largest Ring-billed Gulls, but slightly larger than others. I approached closer and noted that, when compared to a Ring-billed Gull, the bird had duller yellow legs, a stouter bill with black and red spots near the tip of the lower mandible, and a darker gray mantle. [...] The bird was slightly larger than most of the Ring-billed Gulls, although one or two of the biggest Ring-billed Gulls were as large as the bird I was studying. Proportionately, the bird was heavier and larger-headed than a Ring-billed Gull. [...] I estimated the mantle color to be about midway between those of Ring-billed Gull and a Lesser Black-backed Gull. [...] The bill was heavier than the bill of a Ring-billed Gull and had a distinct gonys. The legs were pale gray-green, unlike the bright yellow legs of a Ring-billed Gull. Leg length appeared similar to a Ring-billed Gull. \| The original documentation form event lasted from 07:45:00/09:27:00.	Iowa Ornithologists' Union \| MS 166	11	1

The documentation form by Raymond Cummins is the only one submitted and forms the basis of this record. \| Elimination of similar species: Of the medium sized Gulls only Ring-billed, Franklin's, and Mew Gulls have similar juvenile plumages. The direct size comparison, seen gull being smaller, bill shape and dark color, and lack of white in head eliminates Ring-billed Gull. Mew Gull is eliminated by long dark bill, Ring-billed like jist of bird in flight, and uniform overall color. The long down turned bill and the total improbability of a juvenile Franklin's being in southern Iowa on this date. \| The original documentation form event lasted from 10:19:00/10:30:30 on June 4, 1991 and 09:30:00/09:35:00 on June 5, 1991.

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.

Skuas are easily eliminated by their larger size, heavier bill, and more prominent white patches on the wings. Long-tailed Jaeger is eliminated by the presence of a white crescent on the upper surface of the wing. Pomarine Jaeger can be eliminated by its larger, heavier body size, more prominent white crescent on the wing, presence of white greater underprimary coverts, larger-headed appearance, heavier bill, and general lack of rufous color on the body. \| The original documentation form event lasted from 16:22:00/16:51:00.
