The documentation form by Stephen J. Dinsmore for the 11:25 AM sighting forms the basis of this record. A second form by Stephen J. Dinsmore for the 12:12 PM and 5:40PM sighting was submitted as well. Other documentation forms by Lee A. Schoenewe, Pete Ernzen, Jim Fuller, Thomas H. Kent, Peter C. Petersen, Ed Thelen, Babs Padelford, Loren Padelford, Pam Allen, Reid Allen, Beth Proescholdt, and Mark Proescholdt (two separate forms) were submitted later. Other observers include LaVonne Foote, Nancy Schoenewe, Beth Brown, Tim Schantz, Brian Blevins, Corey Blevins, Bob Livermore, Roland Barth, Kim Eckert, Russ Widner, Phil McFadden, Bill Huser, Eugene Armstrong, and Eloise Armstrong. | Elimination of similar species: The combination of red bill and legs, brown hood, size, very pale gray mantle and upperwings, and black undersides to the inner primaries eliminates several similar species, including Franklin's, Laughing, Little, Bonaparte's, and Ross' gulls. | The original documentation form event lasted from 11:25:00/11:42:00.

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.

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.

Second winter Lesser Black-backed Gull eliminated by smaller size, browner uppertail, and heavily streaked head and underparts. | The original documentation form event lasted from approximately 16:00:00/16:15:00 on November 30, 1986 and 15:55:00/16:08:00 on December 1, 1986.
