Other observers include Bery Engebretsen, Eugene Armstrong, and Eloise Armstrong. | Elimination of similar species: The long, thin neck eliminated ducks and loons and convinced me that the shape of the bird was most certainly a grebe. Western/Clark's shows white rather than gray on the chin, neck, and breast and is larger. Horned Grebes are smaller and also are white on the underparts. Pied-billed could be eliminated by the size and shape of the bill alone. Although fall Eared Grebes are fairly gray, the size equaling Hooded Mergansers and the large bill allowed me to eliminate that species. | The original documentation form event lasted from 16:30:00/16:40:00.

The documentation form by Jim Bangma is the earliest and the one that forms the basis of this record. Another documentation form by Ann Johnson was submitted later. | Elimination of similar species: Double-crested is smaller, with a much thinner neck. There is a noticeable transition from the thin neck to the larger head. In this bird, there was no noticeable widening from the neck to the head. Additionally, Double-crested has a proportionally much smaller and weaker bill. Double-crested's forehead slopes more evenly into the bill. While these differences may be difficult to see in single birds without comparative experience, in direct comparison they are significant. Additionally, the orange facial skin combines with the gular pouch to accentuate the overall orange color of the face. Other extralimital black cormorants can be ruled out on size alone, additionally, most have thinner necks and smaller bills than even Double-crested. | The original documentation form event lasted from 11:00:00/11:02:00.

Despite the great distance and lack of a good view of the wing pattern, I believe the bird was a Pomarine Jaeger. | The original documentation form event lasted from 13:45:00/14:43:00.

At the time I did not realize the importance of this detail, but I recorded it along with my other field notes as I knew from past reading that distinguishing between Long-tailed and Parasitic Jaegers could be tricky. | The original documentation form event occurred around 18:00:00.

Bill was gull-like, but hooked mail different. May have been exagerated [sic] by a darker color than basal portion.
