| Occurrence Remarks |
The documentation form by Robert K. Myers is the only one submitted and forms the basis of this record. Other observers include Eugene Armstrong and Eloise Armstrong. | Elimination of similar species: The gull was too big and had too large of a bill for herring gull. The checkered back + very contrasty head + upper breast with lower are not consistent with herring. Basically size of bird + its bill eliminated most everything. | The original documentation form event lasted from 18:30:00/18:45:00. |
