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.

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.

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.
