Occurrence Remarks |
The documentation form by Steve Dinsmore is the earliest and the one that forms the basis of this record. Other documentation forms by Eugene Armstrong, Eloise Armstrong, and Mark Proescholdt were submitted later. | Elimination of similar species: The body shape, posture, and black-and-white coloration identified the bird as loon. Although some Common Loons may be quite small. I think this bird was too small for even a very small Common Loon. Otherwise, the slender, upturned bill, the head posture, the contrast between the back and the neck, and the gray neck and white throat eliminated Pacific and Common Loons. | The original documentation form event lasted from 13:46:00/15:43:00. |
