Myers, Robert K.	Yellow Rail	Sweet Marsh	Sweet Marsh		The documentation form by Robert K. Myers is the only one submitted and forms the basis of this record.

Along the trailing edge of each wing out from the body about 2" and about 1/2" wide (maybe wider) was a white bar. \| The original documentation form event occurred around 10:00:00.

Johnson, Ann	Prairie Falcon	Swan Wildlife Refuge	Swan Wildlife Refuge, Warren County [incorrect county], IA	Overlook of river bottom, waterfowl refuge	The documentation form by Ann Johnson is the only one submitted and forms the basis of this record. \| Elimination of similar species: The pointed wings and powerful, direct flight identified the bird as a falcon. Size eliminated all but the more likely Peregrine. The pale color and narrow facial markings with light supercilliary all but eliminated the Peregrine. The brief look at the black on the underwing confirmed this. \| The original documentation form event lasted from 15:50:00/15:51:00.	Iowa Ornithologists' Union \| MS 166	33	35
Rare bird documentation form for Merlin at Swan Lake, 1976	Field notes	Birds--Identification Ornithology Rare birds	1976-09-16	1976-09-17	Rare birds documentation form	Rare bird documentation form for a Merlin at Swan Lake in Johnson County, IA on September 16, 1976.	Halmi, Nicholas S.	Merlin	Swan Lake	Swan Lake, Johnson Co., Iowa	Swan L. is 1 mile south from the Coralville Reservoir. The bird was flying over the lake, the bordering mudflats and disappeared within seconds over an adjoining cornfield, continuing its rectilinear, unswerving flight.	The documentation form by Nicholas Halmi is the only one submitted and forms the basis of this record. \| Elimination of similar species: In spite of the first subconscious "gestalt" impression of a Mourning Dove approaching, the square tail, lacking white, falcon wings and greater size rule this one out. The bird seen was definitely too small to be a Peregrine, and had no mustache. It did not have the distinctive facial pattern of the familiar Kestrel either, nor the rufous back and/or wings and tail; it was a dusky bird, not the way Kestrels look to me; nor have I ever seen a Kestrel flying with such blinding speed and so "purposefully". \| The original documentation form event occurred around 15:30:00.

Rare bird documentation form for Pine Warbler west of Coralville Reservoir, 1991	Field notes	Birds--Behavior Birds--Identification Ornithology Rare birds	1991-08-04	N/A	Rare birds documentation form	Rare bird documentation form for a Pine Warbler west of Coralville Reservoir in Johnson County, IA on August 4, 1991.

Surrounded by cornfields. Groves of cultivated pines within 1/2 mile of the area. The bird was first spotted in the top-most branches of a bare (poplar?) snag.	The documentation form by Randall Pinkston is the only one submitted and forms the basis of this record. \| Elimination of similar species: Yellow-throated Vireo has thick, less pointed bill and distinct yellow spectacles. Immature or female Northern (Baltimore) Oriole much larger. \| The original documentation form event lasted from approximately 11:00:00/11:01:00.	Iowa Ornithologists' Union \| MS 166	35	29
Rare bird documentation form for Long-billed Dowitcher at Swan Lake, 1994	Field notes	Birds--Identification Ornithology Rare birds	1994-11-25	N/A	Rare birds documentation form	Rare bird documentation form for two Long-billed Dowitchers at Swan Lake in Johnson County, IA on November 25, 1994.

Kent is the only one submitted and forms the basis of this record. \| Elimination of similar species: These birds did not have the bold streaking of a snipe. I wouldn't believe a Short-billed Dowitcher at this date if I saw it myself. At any rate, the gray neck and some retained thin rufous edge on wing feathers is typical of molting juvenile Long-billed Dowitcher at this date in Iowa. \| The original documentation form event lasted from 15:45:00/16:10:00.

Kent is the only one submitted and forms the basis of this record. Other observers include Ron Harms. \| Elimination of similar species: The size and flight eliminate Kestrel. The dark axillaries eliminate Gyrfalcon and Peregrine Falcon. The long shape eliminates other raptors. \| The original documentation form event lasted from 10:00:00/10:05:00.
