Occurrence Remarks |
The documentation form by Steve Dinsmore is the only one submitted and forms the basis of this record. | Elimination of similar species: The dark hood and wing pattern eliminate all other gulls except Laughing Gull. The small bill and white bar separating the black wingtip from the rest of the wing eliminates Laughing Gull (in adult plumage). | The original documentation form event lasted from 15:40:00/16:30:00. |
