The bill shape, dark cap that included the eye, and presence of two white patches on each side eliminates all other murrelets, especially Kittlitz's. \| The original documentation form event lasted from 15:15:00/15:24:00.

Records Committee review for rare bird sighting of Least Tern at Cone Marsh, 1984	Administrative records Field notes	Bird watching Ornithology Ornithology--Societies, etc	1984-05-19	1993-09-01	Rare birds documentation form	Records Committee review for a Least Tern at Cone Marsh in Louisa County, IA on May 19, 1984. Includes a record review document with votes, a summary of a review, and two documentation forms submitted to the committee.	Bendorf, Carl J.	Least Tern	Cone Marsh Wildlife Management Area	Cone Marsh	State owned marsh of about 700 Acres.	The documentation form by Carl J. Bendorf forms the basis of this record. Another documentation form by Thomas J. Staudt was submitted. \| Elimination of similar species: The obvious possibilities are both Common or Forsters' Terns. At the very most, this bird was perhaps half the size of the gulls. This would put the body length in the general range of 8" long with a wingspread of 24" (according to size of Ring bills in the Natl. Geo. Guide) The Natl. Geo. Guide gives the general size range of Least Tern as 9" long with a wingspread of 20 ". The sizes of the other terns are given as Common L 14 1/2', W 30", and Forsters' L 14 1/2, W=31". Thus on size alone, Least Tern seems to be the only reasonable choice. The short but deeply forked tail also indicates Least Tern. Harrison's SEABIRDS says, on page 182, "Size and hurried flight,..., usually sufficient to clinch identification in northern hemisphere". The flight of this bird was much quicker and fluttery compared to my experience with the slower, deeper, and more deliberate flight of Common and Forster's Terns. \| The original documentation form event lasted from 09:30:00/09:32:00.

Other documentation forms by Jim Dinsmore and Tom Kent were submitted. Other observers include Jim Sinclair and Dick Tetrault. \| Elimination of similar species: The combination of smaller size, bill size, leg length, and wing pattern eliminates other Sterna, especially Common and Forster's Terns. \| The original documentation form event lasted from 18:15:00/19:40:00.

Arctic Tern	Sandpiper Recreation Area	Saylorville Reservoir, Polk County, Iowa	large reservoir	The documentation form by Steve Dinsmore forms the basis of this record.
