| Habitat |
The area of Sweet Marsh where the bird was flushed had a water depth of about two feet. Many large and small clumps of grass covered mounds of earth, there was a shallow marshy spot that was heavily vegitated. Otherwise the area surrounding sighting was similar. This type of habitat covered several acres. The grasses were mostly remanent [sic] of last years growth, with new sprouts over a foot in height. The water was slightly stagnant, and water level was slightly higher than normal because of recent rains. |

| Occurrence Remarks |
The documentation form by Joe Schaufenbuel is the only one submitted and forms the basis of this record. | Elimination of similar species: I can think of no species of bird of similar size with a white patch on hind wing. Other rails would be uniform dark and larger. Perching birds such as a Swamp Sparrow (Melospiza gerogiana) have long tails. Extreme comparisons could be made with Common Snipe (Capella gallinago) which is long billed, has pointed wings, and has a rapid zig-zag flying style. | The original documentation form event occurred around 18:30:00. |

| Event Remarks |
Viewing Conditions: Distance: When flushed the bird was very close at hand, within six feet, but by the time I got my head turned it was at an estimated 10 or more feet. It was watched in flight until it landed, an estimated distance of 90 feet. Optical equipment: Because of close range, and rapid appearance of subject none were used. Light: Sun was at my back as I viewed the bird, the position of the sun was in the northwest, with the bird in the east. The sky had broken clouds, with the sun shining at time of observation. Although sun was close to horizon it still had strong light. Altogether fair viewing conditions. |
