Records Committee review for rare bird sighting for Mountain Bluebird northeast of Lamoni, 1984	Administrative records Clippings (information artifacts) Field notes	Bird watching Ornithology Ornithology--Societies, etc	1984-12-22	1993-09-01	Rare birds documentation form	Records Committee review for a Mountain Bluebird northeast of Lamoni in Decatur County, IA on December 22, 1984. Includes a record review document with votes, an article in Iowa Bird Life, and ten documentation forms submitted to the committee.	Livingston, Jeffrey R.	Mountain Bluebird	Lamoni	1 mile east and 3 miles north of Lamoni Iowa	A small grove of cedar trees around a farmhouse and a mostly frozen pond in a pasture across the road. The cedar trees have many berries.	The documentation form by Jeffrey R. Livingston forms the basis of this record. Other documentation forms by Francis L. Moore, Thomas H. Kent, Eugene Armstrong, Robert K. Myers, Peter C. Petersen, Jim Fuller, Carl J. Bendorf, Raymond Cummins, and Barbara L. Wilson were submitted. Other observers include Tom Johnson, Don Gillaspey, Eloise Armstrong, Betsy Myers, Dennis Thompson, Jim Gillaspey, Dan Long, Mary Lou Petersen, Corey Blevins, Brian Blevins, Lewis Blevins, and many unidentified other observers. \| Elimination of similar species: The bird at one glance was definitely a bluebird. The Eastern and Western Bluebirds both have rust markings on their breast and neck. The Eastern Bluebird has a more stocky shape than the Mountain Bluebird. I had a chance to compare as I had just seen a flock of Easterns about 5 min. before. The immature Eastern has a soeckled breast, this bird had none. The long thin bill eliminates the Shrikes as does the bright blue and the small size. \| The original documentation form event lasted from 12:00:00/12:45:00.	Iowa Ornithologists' Union \| MS 166	13	5
