| Occurrence Remarks |
The documentation form by Jan L. Walter is the only one submitted and forms the basis of this record. Other observers include Jim B. Walter and Edna E. Peters. | Elimination of similar species: Size; Rail shape, flight, and behavior eliminated near-by Blackbirds. It was too early in the year for a downy Rail chick in North Iowa. Also downy chicks would not be able to fly. Very small size and all black color eliminated other Rail species. Even though we did not see the reddish wash on the back, white speckling on the wings, or barring on the flanks; the black, not reddish, underparts eliminated the possibility of a small Virginia Rail. | The original documentation form event lasted from 19:13:00/19:13:00. |
