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.

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.

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.

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.

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.
