Rare bird documentation form for Red-necked Grebe at Four Mile Lake, 1993	Field notes Forms (documents)	Birds--Identification Ornithology Rare birds	1993-06-09	1993-06-23	Rare birds documentation form	Rare bird documentation form for two Red-necked Grebes at Four Mile Lake in Emmet County, IA on June 9, 1993.	Ehresman, Bruce Flaherty, Molly	Red-necked Grebe	Four Mile Lake Wildlife Management Area	T99N, R34W, Sec 8 SE 1/4 at Four Mile Lake Restored Area. ~150 yds NW of NW corner of furthest east parking lot along County Rd. A22.	Restored wetland w/ emergent vegetation - surrounded by grassland	The documentation form by Bruce Ehresman and Molly Flaherty is the only one submitted and forms the basis of this record. \| Elimination of similar species: Head similar to Western Grebe, but this grebe's neck is rusty red color. Body also smaller than western grebe, and bill not as long and pointed. \| The original documentation form event lasted from 10:15:00/11:15:00.	Iowa Ornithologists' Union \| MS 166	32	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.

Other observers include Bery Engebretsen. \| Elimination of similar species: The shape was obviously that of a grebe.
