Records Committee review for rare bird sighting of California Gull at Saylorville Dam, 1993	Administrative records Clippings (information artifacts) Field notes	Bird watching Ornithology Ornithology--Societies, etc	1993-12-06	1995-07-08	Rare birds documentation form	Records Committee review for a California Gull at Saylorville Dam in Polk County, IA on December 6, 1993. Includes a record review document with votes, an article in Iowa Bird Life, and two documentation forms submitted to the committee.	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.

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.

Includes a record review document with votes, a photograph, an article in Iowa Bird Life, and three documentation forms submitted to the committee.	Bray, Tanya	California Gull	Carter Lake	Carter Lake, Pottawattamie County		The documentation form by Tanya Bray forms the basis of this record. Other documentation forms by Loren and Babs Padelford, and Ross Silcock were submitted. Other observers include Jerry Toll and B.J. Rose. \| Elimination of similar species: Both Ring-billed and Herring Gulls are eliminated by bill coloration, size, slightly darker mantle, and eye color. Western, Lesser-black backed would be darker mantled, different bill coloration. \| The original documentation form event lasted from 10:30:00/10:58:00.	Iowa Ornithologists' Union \| MS 166	11	1
Rare bird documentation form for Thayer's Gull at Red Rock Dam, 1993	Field notes	Birds--Identification Ornithology Rare birds	1993-11-13	N/A	Rare birds documentation form	Rare bird documentation form for a Thayer's Gull at Red Rock Dam in Marion County, IA on November 13, 1993.	Pinkston, Randall, 1956-	Thayer's Gull	Red Rock Dam	Lake Red Rock dam, Marion County, Iowa		The documentation form by Randall Pinkston is the only one submitted and forms the basis of this record. Other observers include Jim Fuller. \| Elimination of similar species: Compared with first-winter Herring Gull above. Pale Thayer's may be confused with same-aged Iceland Gull, but Iceland typically much paler than this individual. Iceland should also show pale, mottled tertials and tail which are concolor with the upperparts. This bird's tertials and tail were unpatterned (except at the edges of the tertials) and darker than the remainder of the upperparts. Iceland's folded primaries are paler than the remainder of the mantle, not darker as in this bird. Slaty-backed, Glaucous-winged, and Glaucous-winged X Western hybrid Gulls all larger, have more massive bills, less likely in Iowa. \| The original documentation form event lasted from 10:15:00/10:40:00.

Carter, Dennis L.	Great Crested Flycatcher	Effigy Mounds National Monument	Effigy Mounds National Monument, Allamakee County, Iowa	railroad tracks at base of river bluff (wooded) and ajacent [sic] to Mississippi River " right-of-way bordered by brushy growth	The documentation form by Dennis Carter is the only one submitted and forms the basis of this record. \| Elimination of similar species: I considered the possibility that this might be an Ash-throated Flycatcher, a species that was recorded in Minnesota in Nov., 1990. The bird I saw lacked the pale coloration and slim appearance of Ash-throated. I feel that the bright yellow belly, contrasting with the dark gray chest eliminates Ash-throated. At no time during my observation, did I feel that this bird might be an Ash-throated Flycatcher. \| The original documentation form event lasted from 10:30:00/11:00:00.

Other documentation forms by Maridel Jackson, Ross Silcock, Jane R. Clark, and Jim Sinclair were submitted later. Other observers include John Cecil, Eugene Armstrong, and Eloise Armstrong. \| Elimination of similar species: Northern Goshawk- Although Goshawks have been known to show pointed wings, they are never as pointed as a Falcon's. I have seen many Northern Goshawks and jizz alone would rule this one out. I saw no barring on the tail. One of the prime field marks on a Goshawk are the bright white undertail coverts which this bird did not have. The bird in question also lacked a dark crown. Peregrine Falcon- Size. No dark helmet. Jizz (mentioned above). The bird lacked overall contrast of a Peregrine Falcon. Juveniles would be brown. Prairie Falcon- Color. Prairies are a brown bird in all plumages. The underwing was uniform with no black axillaries. Habitat. Prairies feed almost exclusively on small mammals. \| The original documentation form event occurred around 15:30:00.

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

Van Dyk, John, 1936-	Peregrine Falcon	Sioux Center	Sioux Center, IA 51250		The documentation form by John Van Dyk is the only one submitted and forms the basis of this record. \| Elimination of similar species: Its clear head markings definitely rule out a Prairie Falcon (which is now becoming a regular visitor here in winter), and the bird was much too large to be a smaller (e.g., Merlin). \| The original documentation form event occurred for around five minutes.
