| Occurrence Remarks |
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. |
