Overton, and Chris Edwards were submitted later. Other observers include Mary Edwards, Pam Allen, Reid Allen, Dennis Henrickson, Clem Claphake, Jim Kovanda, and Sandy Kovanda. | Elimination of similar species:From first glance, the Garganey was conspicuously different from other nearby ducks on the lake.

Another documentation form by Ann Johnson was submitted later. | Elimination of similar species: Double-crested is smaller, with a much thinner neck. There is a noticeable transition from the thin neck to the larger head. In this bird, there was no noticeable widening from the neck to the head. Additionally, Double-crested has a proportionally much smaller and weaker bill. Double-crested's forehead slopes more evenly into the bill. While these differences may be difficult to see in single birds without comparative experience, in direct comparison they are significant. Additionally, the orange facial skin combines with the gular pouch to accentuate the overall orange color of the face. Other extralimital black cormorants can be ruled out on size alone, additionally, most have thinner necks and smaller bills than even Double-crested. | The original documentation form event lasted from 11:00:00/11:02:00.

The documentation form by Ann Johnson and Jim Bangma is the only one submitted and forms the basis of this record. | Elimination of similar species: The lack of a pointed tail eliminated even a young Ring-necked Pheasant (confirmed later in the week with observations). Sharp-tailed Grouse have been released in the Loess Hills, but they show a more pointed tail with white at the edges and their flanks are more spotted than barred. Ruffed Grouse has a fan-shaped tail which matches the body color and has a dark subterminal band. We had no doubt that these birds were Prairie Chickens. Lesser Prairie Chicken cannot be eliminated by our sighting but is dismissed based on location and habitat (tall grass vs. short grass prairie). The question of origin then arises. The closest releases of grouse have been Sharp-tailed in the Loess Hills south of Sioux City, but our observations eliminated Sharp-tailed. Greater Prairie Chickens have most recently been released in Ringgold County, some 150-200 miles to the southeast. I discussed possible releases with some birders in the area and no one had any knowledge of released birds. On the other hand, Greater Prairie Chicken nests in South Dakota fairly close to the Iowa border. This map shows the relative abundance of the bird in the plains states based on Breeding Bird Surveys. We therefore feel that it is most likely that these birds come from a native population nearby and might possibly have been a family group. | The original documentation form event lasted from 07:20:00/07:22:00.

The documentation letter by Bob Vane is the only one submitted and forms the basis of this record. Other observers include Jean Vane, Myra Willis, and Lillian Serbousek. | Elimination of similar species: [...] I must say at that particular time, since the bird was new to us, we were not absolutely sure whether it was a Smooth-billed or Groove-billed ani. Upon returning home, however, we found in Bent, "The note of the Smooth-billed ani has been called a wailing or whining whistle - resembling the notes of the wood duck." Our bird's call note was not a whistle at all. And then we found in Pough's Eastern Land Birds under Smooth-billed ani, "The two anis are hard to tell apart except by note, the whining notes of this species being in sharp contrast to the soft double note of the Groove-billed." So for my part, that settled it that our bird was a Groove-billed ani. | The original documentation form event occurred in the afternoon
