The documentation form by Russell Reisz is the earliest and the one that forms the basis of this record. Other documentation forms by Peter Ernzen, Thomas H. Kent, Jim Fuller, Dick Tetrault, Chris Edwards, and Mark Proescholdt were submitted later. Other observers include Beth Proescholdt. | Elimination of similar species: Fulvous Whistling-duck is the most similar species. This species was eliminated because it has a different bill color and a different leg color than the Black-bellied Whistling-duck. The Fulvous Whistling-duck also lacks the white wing patch and the dark belly of the Black-bellied Whistling-duck. These were all points of identification for the species seen at Tomahawk Marsh. | The original documentation form event lasted from 19:58:00/19:58:00.
