Rare bird documentation form for Laughing Gull at Sandpiper Recreation Area at Saylorville, 1999	Field notes	Birds--Identification Ornithology Rare birds	1999-05-22	N/A	Rare birds documentation form	Rare bird documentation form for two Laughing Gulls at Sandpiper Recreation Area at Saylorville in Polk County, IA on May 22, 1999.	Engebretsen, Bery	Laughing Gull	Sandpiper Recreation Area	Saylorville, parking lot at Sandpiper		The documentation form by Bery Engebretsen is the only one submitted and forms the basis of this record. \| Elimination of similar species: I could see both Laughing + Franklin's standing side by side. Laughing were clearly 20-25% larger, as was bill. A more prominent 'gonys' made the bill appear somewhat more hooked. In flight, the wing tips were black + more extensive than Franklins, both above + below. I looked carefully for any trace of white between tip + rest of wing, as well as for any white on the head, and there was none. The eye ring was broken on the front, less so in the back. The Franklin's had a rounder appearance to the head than did the Laughing. In flight, the Laughing's tail was pure white. \| The original documentation form event lasted from 08:05:00/08:35:00.

Ia		The documentation form by Dennis Thompson is the only one submitted and forms the basis of this record. \| Elimination of similar species: Franklin's + this bird were swimming side by side. Bill longer, bulkier. No white in the wing tips while resting. Stretched its wings once, with no white visible in the primaries nor any white bar separating the gray wing from the black primaries. White spots + bar visible in nearby Franklin's. Direct size comparison noted above. \| The original documentation form event lasted from 15:30:00/15:40:00.	Iowa Ornithologists' Union \| MS 166	34	31

Kent is the only one submitted and forms the basis of this record. Other observers include James Huntington and Jim Fuller. \| Elimination of similar species: 1st year Franklin's Gull has more pattern to wings and more extensive tail band. 2nd year Franklin's would have less black in outer wing and more of a half-[illegible]. This bird was not close enough to see the bill well on details on the tail band. \| The original documentation form event lasted from 18:05:00/18:20:00.	Iowa Ornithologists' Union \| MS 166	34	31

Thompson, Dennis	Laughing Gull	Saylorville Lake	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 [sic] in the wing-tips, 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	34	31

Dinsmore, Stephen J.	Franklin's Gull	Saylorville Lake	Saylorville Reservoir, Polk Co.-above dam	resting with other gulls on large reservoir	The documentation form by Steve Dinsmore is the only one submitted and forms the basis of this record. \| Elimination of similar species: The dark hood and wing pattern eliminate all other gulls except Laughing Gull. The small bill and white bar separating the black wingtip from the rest of the wing eliminates Laughing Gull (in adult plumage). \| The original documentation form event lasted from 15:40:00/16:30:00.

Other observers include Thomas Kent, Randy Graesser, John Van Ryebroek, Carol Thompson, and Dick Tetrault. \| Elimination of similar species: Laughing Gull: White in wingtips of adult gull doesn't fit. Bonaparte's Gull: Mantel color seemed too dark for adult bird and white tertial mark on mantel indicates a white trailing edge to wing which doesn't fit. Common Black-headed Gull: same problems as with Bonaparte's. \| The original documentation form event lasted from 13:00:00/13:30:00.	Iowa Ornithologists' Union \| MS 166	34	32

Kent is the only one submitted and forms the basis of this record. Other observers include Carl Bendorf, Carol Thompson, and others. \| Elimination of similar species: Bonaparte's [handwritten note - 'neither is Franklins!] not hooded at this time of year and has lighter wing with white leading edge. In the last several years, Franklin's Gulls in alternate plumage have been recorded in the midwest in winter. \| The original documentation form event lasted from 13:30:00/13:45:00 estimate.

Dinsmore, Stephen J.	Franklin's Gull	Saylorville Lake	Saylorville Reservoir, Polk Co.-at spillway below dam		The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. \| Elimination of similar species: The dark gray wings separated from the black wingtip by a white bar, broad white eye crescents, stocky bill lacking a pronounced gonys and rounder wings eliminate Laughing Gull. The combination of the black head and dark gray mantle eliminates other dark-headed gulls such as Bonaparte's and Common Black-headed gulls. \| The original documentation form event lasted from 16:10:00/17:20:00.

Rare bird documentation form for Herring Gull at MidAmerican Energy Ponds near Council Bluffs, 1985	Field notes	Birds--Identification Ornithology Rare birds	1985-05-24	1985-06-03	Rare birds documentation form	Rare bird documentation form for a Herring Gull at MidAmerican Energy Ponds near Council Bluffs in Pottawattamie County, IA on May 24, 1985.	Wilson, Barbara L.	Herring Gull	MidAmerican Energy Ponds	IPL Settling Ponds, Council Bluffs, Iowa		The documentation form by Barb L. Wilson is the only one submitted and forms the basis of this record. \| Elimination of similar species: Similar to most of the other large immature gulls of the world. Mantle too light for Black-backed group. Wingtips, even in their folded condition, too dark for Glaucous, Glaucous-winged, etc. that leaves a whole mess of light-mouthed large gulls with dark wing tips. Description seems to match young Herring Gull (second summer ?) well enough. Eye color would probably be becoming pale in a Herring of this plumage, but perhaps not, + it might not show at the distance. I have trouble eliminating California Gull, but it is even harder to support that species.	Iowa Ornithologists' Union \| MS 166	34	34
Rare bird documentation form for Herring Gull at Red Rock Reservoir, 1991	Field notes	Birds--Identification Ornithology Rare birds	1991-01-04	1991-01-23	Rare birds documentation form	Rare bird documentation form for a Herring Gull at Red Rock Reservoir in Marion County, IA on January 4, 1991.	Kent, Thomas H. (Thomas Hugh), 1934-	Herring Gull	Lake Red Rock	Red Rock Reservoir, Marion County, Iowa	Des Moines River below dam, water mostly open with ice on edges	The documentation form by Thomas H. Kent is the only one submitted and forms the basis of this record. Other observers include Jim Fuller and Tim Barksdale. \| Elimination of similar species: The color of the back and obvious window in the inner primaries, as well as the rest of the feather tracts, all fit 2nd winter Herring Gull and seem to exclude Lesser Black-backed Gull. The soft parts were somewhat atypical, but I was not bothered much by this because I have seen much variation in Herring Gulls. \| The original documentation form event lasted from 08:10:00/08:25:00 and 12:45:00/13:00:00 (approximate)	Iowa Ornithologists' Union \| MS 166	34	34

(Island View East and West Areas)	sitting on ice and feeding on open water with other gulls	The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. Other observers include Ray Cummins. \| Elimination of similar species: The first-year birds were separated from first-year Iceland Gull by the distinct tail band and the darker primaries and from first-year Herring Gull by head shape, bill size, more uniform body color, and the silvery-white underwing. The adult bird was separated from an adult Iceland Gull by size, bill shape, and more black (still not too much, though) in the wingtips and from an adult Herring Gull by head shape, bill size, and paler wingtips. \| The original documentation form event lasted from 10:05:00/10:30:00 and 13:30:00/13:54:00.

Rusty Pelican Restaurant	River	The documentation form by Bob Cecil is the only one submitted and forms the basis of this record. \| Elimination of similar species: See above discussion. [...] The wingtip pattern is what caught my attention. There was much less darkening to the outer primaries than on accompanying gulls. [...] When viewed fro [sic] underneath, the wingtips of the subject bird were white to the tips, with the exception of very narrow black tips at the tips of the primaries. This was very different from the adult Herring/Ring-bills which had substantial black towards the end of the underwings. \| The original documentation form event lasted from 10:30:00/10:45:00.

Kent is the only one submitted and forms the basis of this record. Other observers include Jim Fuller. \| Elimination of similar species: I distinguished this bird from Herring Gull based on smaller body size, smaller head and bill, shorter wing span, uniform light tan coloration, medium brown (not black) outer primaries, translucent primaries from below, and medium brown tail band. I distinguished it from Iceland Gull by the brown outer primaries, relatively more tan coloration, and medium brown tail band. \| The original documentation form event lasted from 11:40:00/11:50:00.
