Red-necked Phalarope (which would be even more unusual at this date) was eliminated by bill size and shape and unstreaked mantle. | The original documentation form event lasted from 09:35:00/10:15:00.

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.

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.

Red-throated Loon eliminated by thicker, straighter bill, dark back, chin strap, and 3-toned neck pattern. | The original documentation form event lasted from 11:15:00 - 11:30:00 and 11:45:00.- 12:30:00 on November 22 and 08:00:00/08:35:00 on November 23.

Separation from Bonaparte's Gull is discussed above. Little Gull eliminated by its smaller size, dark bill, lack of any black color on the upperwing, and uniformly dark underside to the flight feathers. Ross' Gull eliminated by tail shape, bill size and color, and darker underwing.

The very pale mantle, dark spot behind each eye, and lack of black on the top of the primaries eliminates Franklin's and Laughing gulls. The black underside of the flight feathers, pale gray mantle and wings, white wingtips, and rounded wings eliminates Bonaparte's and Sabine's gulls and kittiwakes. The square tail and wing pattern eliminates Ross' Gull. The smaller size, black underside of the flight feathers, lack of a white "wedge" on the upper surface of the outer primaries, rounder wings, and lack of black on the upper surface of the primaries eliminates Common Black-headed Gull. | The original documentation form event lasted from 09:30:00/09:34:00.

The large size compared to Ring-billed Gulls, heavy build, large, thick bill, prominent white patches on the upper and under surface on the wings, and the presence of a second white "crescent" on the underwing at the base of the primary coverts eliminate both Parasitic and Long-tailed Jaegers. | The original documentation form event lasted from 12:24:00/14:46:00.

The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. | Elimination of similar species: The wing pattern, size, and lack of black marks on the face eliminated any of the smaller gulls (i.e. Bonaparte's). The small size and smaller bill size eliminated California Gull. Ring-billed Gull was eliminated on the basis of the darker mantle and upperwings, large, dark eye, and bill color and shape. | The original documentation form event lasted from 16:03:00/16:41:00.

The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. | Elimination of similar species: The bird was clearly one of the "hooded" gulls. The combination of size, mantle color, and upperwing pattern eliminates all of the hooded gulls except for Franklin's Gull. The larger size, less obvious white eye crescents, larger and longer bill, and extensively dark tips to the underwings eliminated Franklin's Gull. | The original documentation form event lasted from 12:45:00/13:10:00.

The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. | Elimination of similar species: The general body shape and swimming behavior identified the bird as a phalarope. The unstreaked, gray mantle, thicker, bicolored bill, and buffy wash on the underparts eliminates Red-necked and Wilson's phalaropes. | The original documentation form event lasted from 10:38:00/10:52:00 and 10:59:00/11:14:00.

The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. Other observers include Susan Grove, Eugene Armstrong, and Eloise Armstrong. | Elimination of similar species: On the basis of size and general plumage characters, this species could only be confused with Ring-billed Gull, hundreds of which were available for direct comparison. The combination of slightly smaller size, distinct head shape, bill color and shape, dark eye, and slightly darker mantle and upperwings are sufficient to eliminate Ring-billed Gull. | The original documentation form event lasted from 15:42:00/16:53:00.
