Occurrence Remarks |
The documentation form by Stephen J. Dinsmore forms the basis of this record. Another documentation form by Michael D. Overton was submitted. Other observers include Maridel Jackson, Ann Johnson, Aaron Brees, Gordon Brand, and many other unidentified observers. | 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 15:30:00/16:40:00. |
