Other observers include Bery Engebretsen. \| Elimination of similar species: The shape was obviously that of a grebe. The bird was much too large for a Horned or Eared grebe, both of which were seen within an hour of this sighting. The combination of large size, white throat/cheek patch, and bill size and color eliminates all other grebes. \| The original documentation form event lasted from 09:50:00/10:35:00.

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.

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	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.
