The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. Another observer was Brian Warson. | Elimination of similar species: The bird was clearly an alcid. The small size rules out the murres, Razorbill, and guillemots (see earlier discussion). The long, thin bill eliminates Dovekie, Ancient Murrelet, and all of the auklets. The bill shape, dark cap that included the eye, and presence of two white patches on each side eliminates all other murrelets, especially Kittlitz's. | The original documentation form event lasted from 15:15:00/15:24:00.

The documentation form by Stephen J. Dinsmore is the earliest and the one that forms the basis of this record. Other documentation forms by Thomas H. Kent and Jim Fuller were submitted later. Another observer includes Chuck Fuller. | Elimination of similar species: The three most similar species are Herring, Thayer's, and Glaucous gulls in first-basic plumage. The latter was eliminated by its larger size and longer, heavier, bicolored bill. First-basic Herring Gull is much darker overall with primaries darker than the upperwing coverts, a pale window on the inner primaries, and rectrices that are all black. First-basic Thayer's Gull is the hardest to eliminate. Thayer's always show primaries that are as dark or darker than the rest of the wing. The dark tail band of Thayer's is always darker than the mantle and apparently matches the color of the wingtips (Kaufman 1990). | The original documentation form event lasted from 11:30:00/13:10:00.
