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.

Cecil, Robert I.	Thayer's Gull	Lake Red Rock	Tailwaters, Red Rock Res.	Tailwaters/River	The documentation form by Bob Cecil is the only one submitted and forms the basis of this record. Other observers include Tom Kent and Dick Tetrault. \| Elimination of similar species: 1st winter Herring Gull has a very dark secondary bar, often has lighter head, and generally has a much more 'contrastry' appearance involving darker and lighter shades of brown. Overall, the 1st winter Herring is darker brown. \| The original documentation form event occurred in the afternoon.	Iowa Ornithologists' Union \| MS 166	34	35
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.

First-winter Iceland typically much paler, especially the uppersurface of the primaries which are paler than the rest of the mantle, and Iceland should show mottling in the tertials and tail band. I suppose I cannot exclude a heavily-pigmented 'Kumlien's' Gull or an Iceland-Thayer's intergrade as described in Kevin Zimmer's Birding article.

The head appeared more rounded than the Herring gulls and the heavy brown streaking on the nape and neck was more extensive and darker than any Herring present. The bill w/a red gonys mark on the lower mandible was shorter and thinner w/less gonys than the Herrings. They eye iris was dark not yellowish as in all the Herrings present. \| The original documentation form event lasted from 10:00:00/10:35:00.	Iowa Ornithologists' Union \| MS 166	34	35
