Includes a record review document with votes and a documentation form submitted to the committee.	Proescholdt, Beth	Mississippi Kite	Grammer Grove County Wildlife Area	Grammer Grove, Marshall County - hawk-watch	Wooded ridge paralleling Iowa River	The documentation form by Beth Proescholdt is the earliest and the one that forms the basis of this record. Other observers include Eugene Armstrong and Eloise Armstrong. \| Elimination of similar species: Peregrine, imm male, is similar. See above. It was near the size and shape of a Peregrine with long tapered wings & slim body. I knew this wasn't a Peregrine (but an immature male Peregrine & an imm. Mississippi Kite are similar). However the slim, pointed wings of this bird had a different shape; the tail was longer, proportionately, than a Peregrine's, & squared-off rather than tapered like a Peregrine's. I couldn't see if its tail flared at the tip, but in the gap where we had a second, very quick look, Eloise noted its twisting of the tail which is a Mississippi Kite trait. But it was the wing beat that determined absolutely that it was a Mississippi Kite- light, bouyant, [sic] floppy, leisurely, like a moth-so different from the powerful, rapid, direct flight of a Peregrine, and different from any other raptor's flight we have observed. \| The original documentation form event lasted from 10:30:00/10:31:00.

Ross	Sharp-tailed Sandpiper	Riverton Wildlife Management Area	Riverton GMA, Fremont County		The documentation form by Ross Silcock is the only one submitted and forms the basis of this record. Other observers include B.J. Rose, Roger Rose, and Doug Rose. \| Elimination of similar species: [...] It resembled a Pectoral Sandpiper, but differed in the following ways: the crown was streaked, and showed noticeable rufous coloration in the feathering; the off-white superciliary stripe was lengthy and broadened towards the rear; the breast markings were dense as in a Pectoral but did not show a clearcut ending at the whitish belly, but instead ended indeterminately by gradually fading out. [...] Once ready to record, we flushed the bird and it gave a soft series of notes, somewhat like a Lesser Yellowlegs, but rather flat and unmelodious. This call was most unlike the harsh, grating call of a Pectoral Sandpiper. [...] Plumage, time of year, call upon flushing, and key plumage differences from Pectoral Sandpiper, cited above, led us to identify this bird as an adult Sharp-tailed Sandpiper. \| The original documentation form event occurred around 10:30:00.

Lowder, Ken	Arctic Loon	Saylorville Dam	I saw the bird at the dam at Saylorville Lake		The documentation letter by Ken Lowder is the only one submitted and forms the basis of this record. Other observers include John Daniel. \| Elimination of similar species: It acted differently from the Common Loons. When it dove, it "reared back" its head, as though it were "winding up" for the dive. The Common Loons did not do this. In the Walsh article, this behavior is discussed. On page 26 of his article, Walsh states that "both Pacific and Artic Loons have similar diving motions." I do not believe our bird was a Pacific Loon. I base this judgement on overall body size, bill size, and the distribution of white coloration in the head/neck, waterline, and flank areas. Our bird was essentially similar size-wise to the accompanying Common Loons. The bill was also similar to Common Loon. It was not upturned and this as I would have expected with Red-throated Loon.

Falcon not expected to sail so effortlessly on fixed wings for so long. Dark slate-gray plumage and white head seen in good light does not fit with any North American falcon. \| The original documentation form event lasted from 07:50:00/07:50:00.

Another documentation form by Peter Ernzen was submitted later. \| Elimination of similar species: Mute swans usually have a curved neck posture with the bill held below horizontal. Their springtime bill color is expected to be pink. Tundra Swans are expected to have a concave bill, a slight forehead and a smaller proportioned bill.

Pacific Loon	Anderson Goose Lake	Anderson L., Hamilton Co., IA	shallow marsh	The documentation form by Steve Dinsmore is the earliest and the one that forms the basis of this record. Other documentation forms by Mark Proescholdt, James Dinsmore, Thomas Kent, and Beth Proescholdt were submitted later. Other observers include Hank Zaletel. \| Elimination of similar species: The size and shape of the bird were those of a loon. The lack of a dark auricular patch, contrasting neck pattern, dark back and upperwings, and dark bill color all ruled out Yellow-billed Loon. Red-throated Loon was eliminated by bill shape, neck pattern, the dark back and upperwings, and dark area around the eye. Common Loon was eliminated by the dark back and upperwings, shorter, thicker bill, dark area around the eye, evidence of a chinstrap, neck pattern, and contrast between the pale nape and dark back. The bird was clearly a Pacific or Arctic Loon, but which one? Unfortunately, exact identification was not possible, though it was likely a Pacific Loon. \| The original documentation form event lasted from 17:25:00/20:15:00.
