Rare bird documentation form for Yellow Rail south of Emerson, 1988	Field notes	Birds--Identification Ornithology Rare birds	1988-04-29	1988-05-02	Rare birds documentation form	Rare bird documentation form for a Yellow Rail south of Emerson in Mills County, IA on April 29, 1988.	McGrew, David E.	Yellow Rail		3 miles South of Emerson, Mills County, Iowa	In foxtail stubble in government set aside acres. The grass had been clipped about knee high + the machinery passing through had smashed much of it, leaving rows of standing stubble, some leaning into it, + flat rows. Dave said the bird was hard to see in it. This was next to end rows planted to a sparse stand of alfalfa, halfway to Knee high.	The documentation form based upon notes and observations by Dave McGrew is the only one submitted and forms the basis of this record. The documentation form was written by Barb L. Wilson. \| Elimination of similar species: Upland Sandpiper (which he had seen in the same field same day), quail, partridge. I showed Dave rail pictures in Peterson's Eastern guide + the Audubon Master guide. He didn't think much of the yellow rail picture objecting particularly to the white feather edging on the back, + the dull color of legs + bill (which may vary seasonally). After looking through the book he felt rails were the best match, though the bill was a bit too acute but the tail matched. He felt some other species in the Yellow Rail/juvenile Sora area might be it. Except of course there is no other rail like that, at least here. \| The original documentation form event occurred at 19:30:00.	Iowa Ornithologists' Union \| MS 166	33	39
Rare bird documentation form for Lesser Black-backed Gull at Jester Park, 1999	Field notes	Birds--Identification Ornithology Rare birds	1999-12-06	N/A	Rare birds documentation form	Rare bird documentation form for a Lesser Black-backed Gull at Jester Park in Polk County, IA on December 6, 1999.	Brees, Aaron	Lesser Black-backed Gull	Jester Park	Jester Park, Campground 4		The documentation form by Aaron Brees is the only one submitted and forms the basis of this record. \| Elimination of similar species: Herring Gull was eliminated by structure, wing pattern, and tail pattern. California Gull was eliminated by bill coloration and tail pattern. Thayers Gull was eliminated by wing pattern, structure, and over all color.	Iowa Ornithologists' Union \| MS 166	34	36
Rare bird documentation form for Long-tailed Duck at Lake Manawa, 1988	Field notes	Birds--Identification Ornithology Rare birds	1988-10-24	1988-10-27	Rare birds documentation form	Rare bird documentation form for a Long-tailed Duck at Lake Manawa in Pottawattamie County, IA on October 24, 1988.	Grenon, Alan G.	Long-tailed Duck	Lake Manawa	west-central part of Lake Manawa, Pottawattamie County, Iowa	open water and the air over open water	The documentation form by Alan Grenon is the only one submitted and forms the basis of this record. Other observers include Babs Padelford, Loren Padelford, Ruth Green, Betty Grenon, and Bruce Wetteroth. \| Elimination of similar species: This duck was similar in size or slightly larger than nearby Lesser Scaup; most of the bird was a brown slightly lighter than female Lesser Scaup, and without mottling patters. Among ducks that have considerable white on the face, few have white around the eye and extending back to the nape. This eliminates the scoters (also, the bill did not seem large or deep enough for most scoters), Harlequin Duck, Bufflehead, goldeneyes, Smew, scaup, and Northern Pintail (which might have a similar plumage, but with white lower on the neck and side of neck, patterning on the body, speculum, and more differences). Unmarked bill and wing eliminate aberrant Ring-necked Duck and scaup, respectively, and also other divers with contrasting wing markings (including Bufflehead, goldeneyes). The possibility of an aberrant Harlequin Duck exists, but that seems less likely than a young Long-tailed Duck at this location. \| The original documentation form event lasted from 10:15:00/11:15:00 and 17:00:00/18:15:00.

Zobac, Aldrich Zobac, Gladys	Turkey Vulture	Palo	Over fields, 2 or 3 miles SE of Palo, Iowa	Open country, near Cedar River, some woodlots.	The documentation form by Aldrich Zobac and Gladys Zobac is the only one submitted and forms the basis of this record. \| Elimination of similar species: Not a bald eagle, because tail was long and head was small flight not that of a hawk or eagle; much larger than a crow. \| The original documentation form event lasted occurred around 13:30:00.

Grove of trees.	The documentation form by Aldrich Zobac is the only one submitted and forms the basis of this record. Other observers include Gladys Zobac. \| Elimination of similar species: [...] Relative size of bird: Smaller than grackle Slightly larger than Cowbird. [...] Birds were feeding + flying around with huge flock of starlings + sparrows (house sparrows). At first glance - when birds were first sighted - thought we were spotting a cowbird. \| The original documentation form event lasted from 15:15:00/16:00:00.

Rare bird documentation form for Black Scoter at Jester Park at Saylorville Lake, 1989	Field notes	Birds--Identification Ornithology Rare birds	1989-04-09	1989-04-23	Rare birds documentation form	Rare bird documentation form for a Black Scoter at Jester Park at Saylorville Lake in Polk County, IA on April 9, 1989.	Fix, Andrew S.	Black Scoter	Jester Park	50 ft. off Jester State park South end - Saylorville Reservoir	water	The documentation form by Andrew S. Fix is the only one submitted and forms the basis of this record. Other observers include Ann Johnson, Bery Engebretsen, and Steve Dinsmore. \| Elimination of similar species: Other breeding plumage male scoters have characteristic white markings on head, coots have a white bill, moorhens have white along the side. \| The original documentation form event lasted from 16:30:00/17:00:00.

Rare bird documentation form for White-winged Scoter at DeSoto Bend National Wildlife Refuge, 1987	Field notes	Birds--Identification Ornithology Rare birds	1987-03-14	1987-05-20	Rare birds documentation form	Rare bird documentation form with additional notes for a White-winged Scoter at DeSoto Bend National Wildlife Refuge in Harrison County, IA on March 14, 1987.	Fix, Andrew S.	White-winged Scoter	DeSoto National Wildlife Refuge	Iowa part of DeSoto Bend National Wildlife Refuge	water, along shore until alerted, then swam further out and finally flew off	The documentation form by Andrew S. Fix is the only one submitted and forms the basis of this record. Other observers include Craig Harms. \| Elimination of similar species: By general shape, bill characteristic, and color this bird was identified as a scoter. The white/creamish spot between the cere and eye and lack of pale cheeks and throat ruled out the Black Scoter; the bill was Also too extended up the forward part of head for a Black Scoter. I did not feel comfortable differentiating Surf from White-winged based on the morphology of the head. No white wing patch was evident while this bird was on the water. In my experience (see #14), the white patches on the heads of female and immature scoters are very unreliable and highly variable. Fortunately the two key characteristics were plainly visible when the bird flew; paddling along the water for a short distance (confirmed scoter), and prominent white secondaries (confirmed white-winger scoter) \| The original documentation form event lasted from 14:00:00/14:15:00.

Rare bird documentation form for Lincoln's Sparrow north of the IA 17 bridge near Saylorville Reservoir in Polk County, 1988	Field notes	Birds--Identification Ornithology Rare birds	1988-12-18	1988-12-21	Rare birds documentation form	Rare bird documentation form for four Lincoln's Sparrows north of the IA 17 bridge near Saylorville Reservoir in Polk County, IA on December 18, 1988.	Fix, Andrew S.	Lincoln's Sparrow	High Bridge	Des Moines River Bottom north of Rt. #17 Bridge	scrubby fields with variable brush, weeds, thistle, bramble	The documentation form by Andrew S. Fix is the only one submitted and forms the basis of this record. Other observers include Mark Proescholdt. \| Elimination of similar species: -> Song sparrow: These birds (Lincoln's Sparrows) were smaller and had shorter tails than Song Sparrow's [sic], 1 sided central spot, and had buffy breasts, also flight was not the characteristic pumping flight of Song Sparrow -> Savannah Sparrow: These birds lacked yellow lores and were in entirely wrong habitat for Savannah's and had A buffy, fine streaked breast \| The original documentation form event lasted from 08:00:00/12:00:00.

Rare bird documentation form for Prairie Warbler at Lake Ahquabi State Park, 1999	Field notes	Birds--Identification Birdsongs Ornithology Rare birds	1999-05-20	N/A	Rare birds documentation form	Rare bird documentation form for a Prairie Warbler at Lake Ahquabi State Park in Warren County, IA on May 20, 1999.	Bangma, Jim Johnson, Ann	Prairie Warbler	Lake Ahquabi State Park	Lake Ahquabi State Park, Warren County		The documentation form by Ann Johnson and Jim Bangma is the only one submitted and forms the basis of this record. Other observers Jim Sinclair. \| Elimination of similar species: No other warbler has the combination of black outlining the cheek and black flank streaking. The song is unmistakable and we watched this bird sing. While watching the bird we remarked on how it had overshot suitable habitat across the road and that is exactly where Jim Sinclair found this bird the following day. As we watched it forage in the treetops, it was constantly moving to the south and toward better habitat for this species. \| The original documentation form event lasted from approximately 14:30:00/14:40:00.	Iowa Ornithologists' Union \| MS 166	35	30
Rare bird documentation form for Red-necked Grebe at Dale Maffitt Reservoir, 1990	Field notes	Birds--Identification Ornithology Rare birds	1990-03-11	N/A	Rare birds documentation form	Rare bird documentation form for a Red-necked Grebe at Dale Maffit Reservoir in Dallas County, IA on March 11, 1990.	Johnson, Ann	Red-necked Grebe	Dale Maffitt Reservoir	Dale Maffitt Reservoir, Dallas Co., IA	Open water on man-made reservoir; near weedy shoreline	The documentation form by Ann Johnson is the only one submitted and forms the basis of this record. \| Elimination of similar species: Loon were eliminated because, although the neck was somewhat thick, it was longer than a loon. The head was also a bit flatter and it rode higher in the water, just giving a different posture than a loon. Plumage details did not fit any loon. Western Grebe- Thicker neck, some color on neck and white cheek eliminated this one Pied-billed Grebe - Size, bill shape, and other features wrong. Horned/Eared Grebes - Although it gave much the same appearance as a horned grebe, size and bill eliminated both. \| The original documentation form event lasted from 16:34:00/16:42:00.

Rare bird documentation form for Red-necked Grebe at Jester Park, 1990	Field notes	Birds--Identification Ornithology Rare birds	1990-10-28	N/A	Rare birds documentation form	Rare bird documentation form for a Red-necked Grebe at Jester Park at Saylorville Lake in Polk County, IA on October 28, 1990.	Johnson, Ann	Red-necked Grebe	Jester Park	Jester Park, Saylorville Lake, Polk Co., Iowa	Open water	The documentation form by Ann Johnson is the only one submitted and forms the basis of this record. \| Elimination of similar species: Loons were eliminated on the basis of thin neck and posture. Cormorants were eliminated because of straight posture, lack of throat patch, and basic plumage configurations. The bird was obviously larger than a Pied-billed Grebe which would, in addition to the yellow bill, eliminate all but Western Grebe. Western Grebe would have looked much larger than the various waterfowl nearby and would not have shown any rust color on the neck. \| The original documentation form event lasted from 12:45:00/13:05:00.

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.	Iowa Ornithologists' Union \| MS 166	35	31
Rare bird documentation form for Black-legged Kittiwake at Red Rock Dam, 1990	Field notes	Birds--Identification Ornithology Rare birds	1990-12-24	1990-12-26	Rare birds documentation form	Rare bird documentation form for a Black-legged Kittiwake at Red Rock Dam in Marion County, IA on December 24, 1990.	Johnson, Ann	Black-legged Kittiwake	Red Rock Dam	below dam, Red Rock Reservoir, Marion Co., IA	Open water	The documentation form by Ann Johnson is the only one submitted and forms the basis of this record. \| Elimination of similar species: Red-legged Kittiwake would be the only other gull with a semblance of collar at this time of year. It is eliminated by the black bar on the wings and back and the black tailband. \| The original documentation form event lasted from 15:00:00/15:15:00.	Iowa Ornithologists' Union \| MS 166	34	40
Rare bird documentation form for Thayer's Gull at Red Rock Dam, 1995	Field notes	Birds--Identification Ornithology Rare birds	1995-01-01	1995-03-01	Rare birds documentation form	Rare bird documentation form for a Thayer's Gull at Red Rock Dam in Marion County, IA on January 1, 1995.	Johnson, Ann	Thayer's Gull	Red Rock Dam	Red Rock Dam, Marion Co., IA	gravel bar below dam	The documentation form by Ann Johnson is the only one submitted and forms the basis of this record. \| Elimination of similar species: Structure, darker mantle, dark eye, and gray primaries eliminate Herring Gull. Other gulls of intermediate size - Lesser Black-backed eliminated by relative gray of mantle, leg color, and primary color. California eliminated by leg color, primary color, and lack of black marking on bill. Iceland eliminated by dark mantle color \| The original documentation form event lasted from 10:15:00/10:30:00.

Rare bird documentation form for Buff-breasted Sandpiper at Sandpiper Beach at Saylorville Reservoir, 1990	Field notes	Birds--Identification Ornithology Rare birds	1990-10-16	N/A	Rare birds documentation form	Rare bird documentation form for a Buff-breasted Sandpiper at Sandpiper Beach at Saylorville Reservoir in Polk County, IA on October 16, 1990.	Johnson, Ann	Buff-breasted Sandpiper	Sandpiper Recreation Area	Sandpiper Beach, Saylorville Reservoir, Polk Co., IA	sandy beach with short greasy area nearby	The documentation form by Ann Johnson is the only one submitted and forms the basis of this record. \| Elimination of similar species: The larger size and lack of facial pattern and tail pattern in flight eliminated the Baird's Sandpiper. A juvenile Reeve would have been nearer the size of the nearby Killdeer; a Ruff even larger. Both would have a thicker bill than this bird. Upland Sandpiper would have been larger and not had the buffy color. \| The original documentation form event lasted from 16:35:00/16:45:00.	Iowa Ornithologists' Union \| MS 166	34	25
Rare bird documentation form for Black-legged Kittiwake at Lake Red Rock, 1988	Field notes	Birds--Identification Ornithology Rare birds	1988-11-27	N/A	Rare birds documentation form	Rare bird documentation form for a Black-legged Kittiwake at Lake Red Rock in Marion County, IA on November 27, 1988.	Johnson, Ann	Black-legged Kittiwake	Lake Red Rock	below dam - Lake Red Rock, Marion Co, IA	dam on Des Moines River forming reservoir; open river with islands	The documentation form by Ann Johnson is the only one submitted and forms the basis of this record. \| Elimination of similar species: The only other gull with a black collar, the red-legged kittiwake, was eliminated because of the black wing strip and tail band. \| The original documentation form event lasted from 16:02:00/16:48:00.	Iowa Ornithologists' Union \| MS 166	34	40
Rare bird documentation form for Brewster's Warbler at Greenfield Township in Warren County, 1989	Field notes	Birds--Identification Ornithology Rare birds	1989-05-11	1989-05-25	Rare birds documentation form	Rare bird documentation form for a Brewster's Warbler at Greenfield Township in Warren County, IA on May 11, 1989.	Johnson, Ann	Vermivoras	Greenfield Township	My Yard - small acreage in northern Warren County, IA	Mixed open woods and field edge with creek and many shrubs	The documentation form by Ann Johnson is the only one submitted and forms the basis of this record. \| Elimination of similar species: The parent birds were eliminated because of the totally white underparts eliminating the blue-winged and the lack of dark throat and narrower eye stripe eliminating the golden-winged. The golden yellow cap reminded me of a chestnut-sided but the lack of streaking on the back and absence of any markings on the side eliminated this bird also. The combination of field marks leaves the Brewster's as the only logical possibility. \| The original documentation form event lasted from 07:00:00/07:00:00.	Iowa Ornithologists' Union \| MS 166	35	17
Rare bird documentation form for Prairie Falcon at Swan Wildlife Refuge, 1991	Field notes	Birds--Identification Ornithology Rare birds	1991-10-27	N/A	Rare birds documentation form	Rare bird documentation form for a Prairie Falcon at Swan Wildlife Refuge in Marion County, IA on October 27, 1991.	Johnson, Ann	Prairie Falcon	Swan Wildlife Refuge	Swan Wildlife Refuge, Warren County [incorrect county], IA	Overlook of river bottom, waterfowl refuge	The documentation form by Ann Johnson is the only one submitted and forms the basis of this record. \| Elimination of similar species: The pointed wings and powerful, direct flight identified the bird as a falcon. Size eliminated all but the more likely Peregrine. The pale color and narrow facial markings with light supercilliary all but eliminated the Peregrine. The brief look at the black on the underwing confirmed this. \| The original documentation form event lasted from 15:50:00/15:51:00.	Iowa Ornithologists' Union \| MS 166	33	35
Rare bird documentation form for Eastern Phoebe at Cherry Glen Recreation Area at Saylorville Lake, 1988	Field notes	Birds--Identification Ornithology Rare birds	1988-11-12	1988-11-26	Rare birds documentation form	Rare bird documentation form for an Eastern Phoebe at Cherry Glen Recreation Area at Saylorville Lake in Polk County, IA on November 12, 1988.	Johnson, Ann	Eastern Phoebe	Cherry Glen Recreation Area	Cherry Glen, Saylorville Lake, Polk Co., IA	Edge of woods near open field along lakeshore	The documentation form by Ann Johnson is the only one submitted and forms the basis of this record. \| Elimination of similar species: Yellow wash, lack of wing bars, and tail bobbing eliminated the eastern wood-pewee. \| The original documentation form event lasted from 08:51:00/08:51:00.

Rare bird documentation form for Townsend's Solitaire at Lake Ahquabi State Park, 1997	Field notes	Birds--Behavior Birds--Identification Birdsongs Ornithology Rare birds	1997-04-13	N/A	Rare birds documentation form	Rare bird documentation form for a Townsend's Solitaire at Lake Ahquabi State Park in Warren County, IA on April 13, 1997.	Johnson, Ann	Townsend's Solitaire	Lake Ahquabi State Park	Lake Ahquabi SP, Warren Co., IA		The documentation form by Ann Johnson is the only one submitted and forms the basis of this record. Other observers include Aaron Brees and Jim Sinclair. \| Elimination of similar species: Female bluebirds are similar in size and structure and have similar eye rings. The lack of any blue on the wings and tail and the presence of white outer tail feathers eliminates all bluebirds. \| The original documentation form event lasted from 14:45:00/15:45:00.

Rare bird documentation form for Black Scoter at Jester Park at Saylorville Lake, 1989	Field notes	Birds--Identification Ornithology Rare birds	1989-04-09	N/A	Rare birds documentation form	Rare bird documentation form for a Black Scoter at Jester Park at Saylorville Lake in Polk County, IA on April 9, 1989.	Johnson, Ann	Black Scoter	Jester Park	Jester Park area of Saylorville Lake, Polk County, IA	Large impoundment with much open water	The documentation form by Ann Johnson is the only one submitted and forms the basis of this record. Other observers include Andy Fix. \| Elimination of similar species: The coot was eliminated by bill color and general body shape. Other scoters were eliminated by the rounder head shape, lack of any white on the head or body, and by the distinctive bill color and pattern. \| The original documentation form event lasted from 17:20:00/17:30:00.	Iowa Ornithologists' Union \| MS 166	33	13
Rare bird documentation form for Red-necked Grebe at Saylorville Reservoir, 1993	Field notes	Birds--Identification Ornithology Rare birds	1993-11-22	N/A	Rare birds documentation form	Rare bird documentation form for a Red-necked Grebe at Saylorville Reservoir in Polk County, IA on November 22, 1993.	Johnson, Ann	Red-necked Grebe	Saylorville Lake	Saylorville Reservoir, Polk County, IA	Open deep water	The documentation form by Ann Johnson is the only one submitted and forms the basis of this record. Other observers include Bery Engebretsen, Eugene Armstrong, and Eloise Armstrong. \| Elimination of similar species: The long, thin neck eliminated ducks and loons and convinced me that the shape of the bird was most certainly a grebe. Western/Clark's shows white rather than gray on the chin, neck, and breast and is larger. Horned Grebes are smaller and also are white on the underparts. Pied-billed could be eliminated by the size and shape of the bill alone. Although fall Eared Grebes are fairly gray, the size equaling Hooded Mergansers and the large bill allowed me to eliminate that species. \| The original documentation form event lasted from 16:30:00/16:40:00.
