The documentation form by Steve Dinsmore forms the basis of this record. Other documentation forms by Bob Myers, Mark Proescholdt, Beth Proescholdt, Thomas H. Kent, Jim Fuller, Francis L. Moore, Robert Cecil, and Paul Martsching were submitted. | Elimination of similar species: The darker body plumage and dark tail band eliminate Iceland Gull (Kumlien's form). The smaller size, smaller, more delicate bill, more rounded head, silvery white underwing pattern, more uniform body color, and more uniform upperwing pattern eliminate first winter Herring Gull. | The original documentation form event lasted from 10:50:00/11:55:00 and 15:50:00/16:05:00 on November 23, 1986 and 14:50:00/15:35:00 on November 24, 1986.

California Gull was eliminated by the darker mantle, darker underwing and dark carpal bar, lack of a dark spot on the bill, and by the dark smudge at the base of the bill(this is characteristic of 3rd summer Lesser Black-backed Gulls and is never present on California Gulls). | The original documentation form event lasted from 10:08:00/12:10:00.

Another observer includes Susan Grove. | Elimination of similar species: I am uncomfortable committing to California Gull given the brief and distant view I had, and my limited past experience with the species. My fear is that this was just a small Herring Gull. Herring can be quite variable in overall size, bill size, and in terms of color and shade of the first-winter plumage. Supposedly 10-15% of first-winter Herrings' can have a "dipped-in-ink" bill in the fall (Harrison 1983 or Grant 1986?). | The original documentation form event lasted from 12:30:00/15:30:00.

The checkered back + very contrasty head + upper breast with lower are not consistent with herring. Basically size of bird + its bill eliminated most everything. | The original documentation form event lasted from 18:30:00/18:45:00.

The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. | Elimination of similar species: The combination of size, bill shape, and wing and tail patterns eliminates all other shorebirds. The most similar species would probably be Sanderling and Dunlin, both of which would be much smaller than this bird. | The original documentation form event lasted from 08:55:00/09:10:00.
