Includes a record review document with votes and two documentations submitted to the committee.	Brogie, Mark A. Wickham, Peter P.	Iceland Gull	Le Claire	[...] along the Mississippi River approximately one-half mile north of the Interstate 80 bridge in Scott County, Iowa.		The documentation form by Mark Brogie and Peter P. Wickham forms the basis of this record. Another documentation form by Paul Martsching was submitted. Another observer includes Steve Dinsmore. \| Elimination of similar species: [...] The bird was in the company of several Herring Gulls (Larus argentatus) and three subadult Glaucous Gulls (Larus hyperboreus). Two of the Glaucous Gulls were light plumaged birds lacking a gray mantle and, since eye color was not noted, may have been either first or early second winter birds. The third Glaucous was quite buffy and was undoubtably [sic] a first winter bird. The Iceland Gull was first observed being chased by a light-phased Glaucous and was distinctly smaller and lighter colored. It also flew with a faster wingbeat and had a more buoyant flight than that of the larger bird. Glaucous Gulls were also observed chasing Herring Gulls but at no time was intraspecific chasing observed. During several instances two Glaucous Gulls were observed resting on the water or sitting on the ice together, but the Iceland always remained isolated from these birds. At one point the Iceland Gull circled overhead at a distance of approximately 40 yards in the company of a light-phased Glaucous and an immature Herring Gull, and characteristics between the species were well noted. The plumage of the Iceland was wholly white with a faint buffy tinge, yet distinctly whiter than the Glaucous Gull. The size difference between the Glaucous and the other two species was apparent as the Iceland and Herring were of approximately equal size. The head and bill of the Iceland Gull appeared less robust in shape than the Glaucous although both species had a bicolored bill with a flesh colored base and dark tip. [...] The brown barring of the undertail coverts of the Iceland appeared heavier and more noticable [sic] than in its white-winged congeneric counterpart, and contrasted particularly with the whitish tail. \| The original documentation form event lasted for approximately twenty minutes.

Petersen, Peter C.	Iceland Gull	Lock and Dam 15	Location: Davenport. County: Scott	General: Chanel [sic] of Miss. R., near middle of river when standing. Specific: 1/2 - 3/4 mi. above Lock + Dam 15.	The documentation form by Peter C. Petersen forms the basis of this record. Other documentation forms by Ann Barker, Mary Lou Petersen, and Bill Barker were submitted. Other observers include Steve Dinsmore, Paul Martsching, Pete Wickham, Mark Brogie, Lewis Blevins, Corey Blevins, Brett Ashford, and Dale Dickinson. \| Elimination of similar species: Glaucous Gull eliminated by size, wing extention [sic] well beyond tail. Flight, headshape, all emphasized by direct comparison with Glaucous Gulls. The next afternoon Bill Barker compared this bird to two different sized Glaucous Gulls and it was smaller than the smaller Glaucous Gull. Plumage lighter than Glaucous also. \| The original documentation form event lasted from 11:40:00/12:10:00.	Iowa Ornithologists' Union \| MS 166	11	4

Kent, Pam Allen and Reid Allen, Jeff Dankert, and Ann Johnson were submitted later. Other observers include Russ Widner, Kelly McKay, Tim Schantz, Gerald White, Eloise Armstrong, Eugene Armstrong, and Fred Lesher. \| Elimination of similar species: The long legs, upright posture, and long neck were clearly features of a whistling-duck. The extensive rufous color on the belly, dark back edged with tawny, lack of any white on the upperwing, and dark bill and legs eliminate Black-bellied Whistling-Duck. \| The original documentation form event lasted from 13:30:00/14:10:00.

Includes a record review document with votes, correspondence about the bird sighting, seven photographs and photocopies of them, and a documentation form submitted to the committee.	Silcock, W. 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.

Includes a record review document with votes, two articles in Iowa Bird Life, and five documentation forms submitted to the committee.	Kent, Thomas H. (Thomas Hugh), 1934-	Sharp-tailed Sandpiper	Coralville Lake	w. of Greencastle corner, Coralville Res., Johnson Co., Iowa	wet marshy area with low vegetation and mud flats.	The documentation form by Thomas H. Kent forms the basis of this record. Other documentation forms by Ann Johnson, Jim Fuller, Carol Thompson, and Randy Pinkston were submitted. Other observers include Jane Huntington, James Huntington, Jim Sandrock, John Cordell, John Daniel, Mary Noble, Ken Lowder, and Tim Schantz. \| Elimination of similar species: The only other species worthy of consideration is Pectoral Sandpiper. The most distinctive feature is the plain, cinnamon-buff breast without bib line or streaking centrally. The soft breast color shaded off evenly to the lower belly and throat. Some pectorals had very week [sic] breast markings, but on close inspection all had streaks and a sharp bib line. The solid rusty cap differed from any pectorals; some pectorals appeared a bit rusty on the cap, but some streaking was seen on such individuals. The eye line appeared white, and it dropped and widened posteriorly. Some pectorals had light eye lines but they were off-white, less distinct, and straighter. The juvenile feathers of the upper parts were edged with rufous; this was especially prominent on the tertials. Some pectorals appeared to have rusty edging on the tertials, but this was dependent on lighting and at least one rufous appearing pectoral had the color more in the center of the feathers with grayer edging. The gray smudging on the undertail coverts I saw once and only had a glance at a nearby pectoral for comparison, so I am not very confident of this mark. \| The original documentation form event lasted from 09:20:00/09:25:00, 09:55:00/10:00:00, and intermittently 16:15:00/17:00:00.

Sharp-tailed Sandpiper	Credit Island	Credit Island Harbor seen from S. Concord St., Davenport, Scott Co	mud flat on Miss.	The documentation form by Peter C. Petersen forms the basis of this record. Another documentation form by Brian Blevins was submitted later. \| Elimination of similar species: Pectoral Sandpipers, available side-by-side, were slightly larger, legs & bill a bit longer than Sharp-tailed. White eyebrow on Pectorals did not broaden behind eye cap not as richly colored in Pectorals. Pectorals had streaking across buff breast wash uniformly to lower edge of buff. Back of Sharp-tailed seemed more uniformly rich brown than those of the Pectorals. Birds all departed downstream on Miss. before photos could be attempted. \| The original documentation form event lasted from 15:50:00/15:55:00.	Iowa Ornithologists' Union \| MS 166	10	4

Gyrfalcon	Lake Red Rock	Red Rock Reservoir, Marion Co. above the dam	flyover the ice	The documentation form by Matthew Kenne is the only one submitted and forms the basis of this record. \| Elimination of similar species: The lack of facial pattern and white throat and chest rule out peregrine, as the bird was flying almost directly into the sun (perpendicular to me). It wasn't as pale or brown as a prairie, and with shadow and distance there wasn't any dark/light pattern to the underwing. It wasn't black as a crow + the shape was wrong. Eagles were patterned and obviously larger. \| The original documentation form event occurred around 13:10:00.	Iowa Ornithologists' Union \| MS 166	9	4

Other documentation forms by Maridel Jackson, Ross Silcock, Jane R. Clark, and Jim Sinclair were submitted later. Other observers include John Cecil, Eugene Armstrong, and Eloise Armstrong. \| Elimination of similar species: Northern Goshawk- Although Goshawks have been known to show pointed wings, they are never as pointed as a Falcon's. I have seen many Northern Goshawks and jizz alone would rule this one out. I saw no barring on the tail. One of the prime field marks on a Goshawk are the bright white undertail coverts which this bird did not have. The bird in question also lacked a dark crown. Peregrine Falcon- Size. No dark helmet. Jizz (mentioned above). The bird lacked overall contrast of a Peregrine Falcon. Juveniles would be brown. Prairie Falcon- Color. Prairies are a brown bird in all plumages. The underwing was uniform with no black axillaries. Habitat. Prairies feed almost exclusively on small mammals. \| The original documentation form event occurred around 15:30:00.
