| Occurrence Remarks |
The documentation form by Steve Dinsmore is the only one submitted and forms the basis of this record. | Elimination of similar species: Herring Gull eliminated by larger size, lighter mantle color, lack of black and red spots on bill, and wrong leg color (pink, although a very few Herring Gull show yellowish legs). Ring-billed Gull eliminated by smaller size, lighter mantle color, lack of a black ring on bill, and by yellower leg color. | The original documentation form event lasted from 13:13:00/14:08:00. |
