| Occurrence Remarks |
The documentation form by Ken Lowder is the only one submitted and forms the basis of this record. | Elimination of similar species: Sora; eliminated by size and color. Yellow rail: absolute lack of white wing patches; My bird was black - with no suggestion of lighter color anywhere. Virginia rail: eliminated by size and color of bird Could possibly have been a rail chick of another species - ruled out because of presence of chicks at this late date + would have been extremely extraordinary; and because chicks would be incapable of flight. | The original documentation form event occurred around 11:00:00. |
