| Occurrence Remarks |
The documentation form by Carl J. Bendorf is the only one submitted and forms the basis of this record. Other observers include Thomas Kent, Randy Graesser, John Van Ryebroek, Carol Thompson, and Dick Tetrault. | Elimination of similar species: Laughing Gull: White in wingtips of adult gull doesn't fit. Bonaparte's Gull: Mantel color seemed too dark for adult bird and white tertial mark on mantel indicates a white trailing edge to wing which doesn't fit. Common Black-headed Gull: same problems as with Bonaparte's. | The original documentation form event lasted from 13:00:00/13:30:00. |

| Event Remarks |
Viewing Conditions: After returning, I relocated the bird standing on the edge of ice about 600 yards (estimated) away. The sky was overcast and the viewing conditions were of medium quality. The bird was immediately adjacent to a group of about 20 Ring-billed and several Herring Gulls. Overall, there were about 400 gulls present. With a 22X scope, I noted the following features which I wrote down immediately after viewing the bird (retyped below the next day along with the rest of this form): |
