Occurrence Remarks |
The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. | Elimination of similar species: The wing pattern, size, and lack of black marks on the face eliminated any of the smaller gulls (i.e. Bonaparte's). The small size and smaller bill size eliminated California Gull. Ring-billed Gull was eliminated on the basis of the darker mantle and upperwings, large, dark eye, and bill color and shape. | The original documentation form event lasted from 16:03:00/16:41:00. |
