| Occurrence Remarks |
The documentation form by Ann Johnson is the earliest and the one that forms the basis of this record. Other observers include Reid Allen, Pam Allen, Eugene Armstrong, and Eloise Armstrong. | Elimination of similar species: Red-throated and Yellow-billed Loons could both be eliminated by the horizontal head and bill. This bird also showed a more rounded head and definite black/white contrast which was lacking in the Red-throated Loon I had observed six days earlier. Common Loon was eliminated by combination of size, smaller bill, distinct line separating white and black feathers, and ultimately by the chinstrap. | The original documentation form event lasted from 12:10:00/12:30:00. |

1990-25 |
| Event Remarks |
The bird was viewed across the water at a distance of 200-400? yards through a scope at 25x-45x. At first the sky was overcast, but during the time of observation the lighting kept improving which probably allowed for clearly seeing the chinstrap. |
