Rare bird documentation form for Prairie Falcon between Treynor and Carson, 1995	Field notes	Birds--Identification Ornithology Rare birds	1995-03-03	1995-03-04	Rare birds documentation form	Rare bird documentation form for a Prairie Falcon between Treynor and Carson in Pottawattamie County, IA on March 3, 1995.	Kent, Thomas H. (Thomas Hugh), 1934-	Prairie Falcon	Treynor Carson	between Treynor and Carson on highway 92, Pottawattamie Co., IA	gently rolling hills; small stream with scattered trees.	The documentation form by Thomas H. Kent is the only one submitted and forms the basis of this record. Other observers include Jim Fuller and Dick Tetrault. \| Elimination of similar species: The falcon shape was clear to us. The bird was flying directly into a strong southwest wind, but I don't think an accipiter's wing could be that pointed even in a strong wind. The bird was too large and plain to be a kestrel and the flight pattern and behavior were unlike any of the many kestrels seen that day. The light color and open farmland habitat favor Prairie over Peregrine. A Merlin would be smaller and darker. However, I would not have identified this bird as to species with out seeing the underwing pattern. \| The original documentation form event occurred at approximately 12:00:00.

Widner, Russ	Prairie Falcon	Yale	South of Yale IA	Bean Field	The documentation form by Russ Widner is the only one submitted and forms the basis of this record. Other observers include Norm Larsen. \| Elimination of similar species: The size, manner of flying + facial coloration eliminate even a [illegible] female Kestrel. The size, facial pattern, probable axillary pigmentation + lack of strong tail bars eliminate Merlin. The head + face pattern + lack of a broad sideburn a helmet, coloration + somewhat shallower wing beat rule against Peregrine. The face pattern, wing shape, manner of flying + lack of a white rump patch eliminate Harrier. \| The original documentation form event occurred around 15:00:00.

Numerous perches and open space for flight.	The documentation form by Bill Huser is the only one submitted and forms the basis of this record. Other observers include Jerry Probst and Bob Moritz. \| Elimination of similar species: The distinct tear marks eliminated all hawks but falcons and also eliminated the Merlin. Long wings, relative to the tail, and body size eliminated Gyrfalcon. Size and direct comparison eliminated Kestrel. Lack of dark "helmet" eliminated Peregrine Falcon. \| The original documentation form event lasted from 16:45:00/16:50:00.	Iowa Ornithologists' Union \| MS 166	33	35

Rare bird documentation form for Yellow Rail at Sweet Marsh, 1978	Field notes	Birds--Identification Ornithology Rare birds	1978-04-29	1978-04-30	Rare birds documentation form	Rare bird documentation form for a Yellow Rail at Sweet Marsh in Bremer County, IA on April 29, 1978.	Schaufenbuel, Joseph P.	Yellow Rail	Sweet Marsh	Sweet Marsh, which is located one mile East of Tripoli, Bremer County, IA.	The area of Sweet Marsh where the bird was flushed had a water depth of about two feet. Many large and small clumps of grass covered mounds of earth, there was a shallow marshy spot that was heavily vegitated. Otherwise the area surrounding sighting was similar. This type of habitat covered several acres. The grasses were mostly remanent [sic] of last years growth, with new sprouts over a foot in height. The water was slightly stagnant, and water level was slightly higher than normal because of recent rains.	The documentation form by Joe Schaufenbuel is the only one submitted and forms the basis of this record. \| Elimination of similar species: I can think of no species of bird of similar size with a white patch on hind wing. Other rails would be uniform dark and larger. Perching birds such as a Swamp Sparrow (Melospiza gerogiana) have long tails. Extreme comparisons could be made with Common Snipe (Capella gallinago) which is long billed, has pointed wings, and has a rapid zig-zag flying style. \| The original documentation form event occurred around 18:30:00.
