The documentation form by Stephen J. Dinsmore forms the basis of this record. Another documentation form by Michael D. Overton was submitted. Other observers include Maridel Jackson, Ann Johnson, Aaron Brees, Gordon Brand, and many other unidentified observers. | 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 15:30:00/16:40:00.

The documentation form by Stephen J. Dinsmore is the earliest and the one that forms the basis of this record. Another documentation form by James J. Dinsmore was submitted later. | Elimination of similar species: The dark coloration, gull-like shape, and white color in the primary shafts identified both birds as jaegers. Initially, I thought the bird I saw on the 10th was a Parasitic, mainly because of the size and seemingly bright, rust-colored underparts. However, better viewing conditions later showed that the underparts were instead a pale brown color and lacked any hint of rusty color. Long-tailed Jaeger was easily eliminated by size, shape of the central rectrices, and the greater amount of white in the wing. Parasitic Jaeger was more difficult to rule out. The combination of size, wing shape, amount of white in the wing, shape of the central rectrices, and bill size was used to rule out juvenile Parasitic Jaeger. | The original documentation form event lasted from 09:35:00/12:33:00 on November 10, 1996 and 10:55:00/16:05:00 on November 11, 1996.

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.

Compared directly to a Sanderling, this bird had a longer neck, a dark cap, a black spot around the eye, and darker upperwings which were particularly visible in flight. 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.

Also, a Double-created Cormorant has a neck which is always longer than the tail (in flight) and looks conspicuously large-headed and thick-necked when seen overhead.

The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. | Elimination of similar species: I immediately recognized the bird by the call note, which is very distinctive. Additionally, the black throat, yellow wash on the breast, and chestnut shoulder patch were diagnostic. | The original documentation form event lasted from 08:55:00/09:22:00.

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 bird was in the company of Ring-billed and Herring gulls which were easily eliminated on the basis of mantle color. California Gull is slightly smaller, is lighter-mantled, and shows more white in the primaries. Great-black-backed, Slaty-backed, and Western gulls are all larger and have heavier bills. | The original documentation form event lasted from 15:10:00/15:30:00.
