Rare bird documentation form for Red-necked Grebe at Jester Park, 1990	Field notes	Birds--Identification Ornithology Rare birds	1990-10-28	N/A	Rare birds documentation form	Rare bird documentation form for a Red-necked Grebe at Jester Park at Saylorville Lake in Polk County, IA on October 28, 1990.	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.

Red-legged Kittiwake, the one gull to share the neck collar, was eliminated by the black carpal bar and black tips to tail feathers. \| The original documentation form event lasted from 10:10:00/10:30:00.

Other observers include Bery Engrebretsen, Eugene Armstrong, Eloise Armstrong, Pam Allen, Reid Allen, and others from the Des Moines Audubon. \| Elimination of similar species: Most ducks were eliminated by the angle/slope of the head and bill and the size of the bill. Although there was a similarity of head profile to the Common Eider, the facial spots eliminated any eider.

Other observers include Babs Padelford, BJ Rose, Ross Silcock, and Tim Schantz. \| Elimination of similar species: Cormorants could be eliminated by bill shape, among other characteristics.

[...] The three birds seen were about the size of Herring Gulls in typical first year plumage.
