Johnson, Ann	Palm Warbler	Greenfield Township	My yard in northern Warren County, Iowa	Open riparian edge	The documentation form by Ann Johnson is the only one submitted and forms the basis of this record. \| Elimination of similar species: Other yellow rumped warblers were eliminated by the bright yellow undertail coverts contrasting with the buffy breast and belly. \| The original documentation form event lasted from 11:20:00/11:25:00.

Rare bird documentation form for Laughing Gull at Saylorville Lake, 1987	Field notes	Birds--Identification Ornithology Rare birds	1987-06-29	1987-06-30	Rare birds documentation form	Rare bird documentation form for a Laughing Gull at Saylorville Lake in Polk County, IA on June 29, 1987.	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

Kent, Thomas H. (Thomas Hugh), 1934-	Laughing Gull	Babcock Access	Babcock Access, Coraville Res., Johnson Co., Iowa	Open, wide part of reservoir with mud flats.	The documentation form by Thomas H. 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

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
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.

The documentation form by Kevin Healy is the only one submitted and forms the basis of this record. Other observers include Karl Jungbluth. \| Elimination of similar species: The bird was soaring above the river in the vicinity of two adult Bald Eagles. We saw a large dark buteo similar in size to the Bald Eagles. Head projected less than 1/2 the length of the tail, noticeably less than that of the adult Bald Eagles in view at that time. \| The original documentation form event lasted from 12:50:00/12:53:00.

Healy, Kevin	Golden Eagle	Y Camp	YMCA Camp northwest of Boone IA	Soaring above Des Moines River	The documentation form by Kevin Healy is the only one submitted and forms the basis of this record. \| Elimination of similar species: Turkey Vulture: similar in size, but flight different (i.e., this bird did not rock back and forth despite fairly stiff winds during time of observation). Also, wings were held flatter than what I expect for a Turkey Vulture. Harlan's Hawk: Breast and belly solid in color, no barring on tail, wing shape unlike that of Red-tailed Hawk. Size difference. Dark phase Rough-legged Hawk: No speckling on breast or belly, tail longer with thinner terminal band. Size difference. \| The original documentation form event lasted from 11:45:00/11:48:00.

Walter is the only one submitted and forms the basis of this record. Other observers include Jim B. Walter. \| Elimination of similar species: Small head, longer tail, absence of any white in plumage eliminated Bald Eagle. Size much larger than common, familiar Red-tailed Hawk eliminated dark morph buteos as did lack of strong contrast between flight feathers and under wing linings. It did not have the 2-toned under wings, strong dihedral or rocking flight of the Turkey Vulture. \| The original documentation form event lasted from 16:00:00/16:05:00.	Iowa Ornithologists' Union \| MS 166	33	31
