| Occurrence Remarks |
The documentation form by Ann Johnson is the earliest and the one that forms the basis of this record. Other documentation forms by Thomas H. Kent, Jim Fuller, and Chris Edwards were submitted later. | Elimination of similar species: The apparent size differential, bill size and clean line to the neck eliminated Common and Yellow-billed Loon. Red-throated is approximately the same size but the bill appears upturned because of the angular shape of the lower edge. Red-throated also has a head lighter than the body. A chinstrap would not be seen on any other species. Grebes were eliminated by thickness of neck and general jizz. | The original documentation form event lasted from 13:30:00/13:40:00. |
