Kent is the earliest and the one that forms the basis of this record. Other documentation forms by Jim Fuller, Ann Johnson, and Carol Thompson. Other observers include Ken Lowder, Jim Scheib, Bud Goode, Cal Knight, Bernie Knight, and Beth Brown. \| Elimination of similar species: The head posture resembled a cormorant, but the bill, overall coloration, and behavior quickly excluded that possibility. The size and bill led me to an immediate identification. I was puzzled about the plumage. I expected to see a juvenile or basic-plumaged bird, but the distribution of dark coloration was that of alternate plumage. I assume that the red/black throat, lines of neck, and gray tones had faded to give one rather uniform color. The drab light may have contributed some to the failure to see color differences, but the last observation was relatively close and the texture of the feathers could be seen. \| The original documentation form event lasted from 07:45:00-08:30:00 and 12:20:00-12:45:00.

Rose, Doug Rose, Roger Rose, Dave Starr, and Jerry Toll. \| Elimination of similar species: Pacific Loon, eliminated by red color of throat patch and shape of bill. This bird's bill was more like that of a Eared Grebe; that is, very slender and not as loon-like as that of Pacific Loon. Pacific Loon's bill looks like a small Common Loon.
