The documentation form by Stephen J. Dinsmore forms the basis of this record. Other documentation forms by Jim Fuller, Thomas H. Kent, Chris Edwards, and Ray Cummins were submitted. Other observers include Tom Johnson, Dennis Henrickson, Jim Sinclair, and many unidentified other observers. | Elimination of similar species: The size, shape, and white in the primaries ruled out all gull species. The combination of size, the large bill, large amount of white on the upperwing, white color in the underpirimary coverts, and blunt-tipped central rectrices rule out juvenile Long-tailed and Parasitic jaegers. | The original documentation form event lasted from 13:12:00/13:55:00 on November 16, 1996 and 15:40:00/16:30:00 on November 27, 1996.

[...] The bird is not any larger than some of the ring-bills--some of the ring-bills are smaller. The larger ring-bills are almost as big as this bird, and it is distinctly smaller than a number of Herring Gulls in the same field. The bill is much smaller and thinner; the head is small. [...] The striking thing about this bird is the size, bill shape and head shape compared to the nearby herrings and very distinct smudge through the eye." | The original documentation form event lasted from around 09:10:00 for several minutes and 15:55:00 for many minutes.

Other observers include Ross Silcock, Tim Schantz, Eugene Armstrong, Eloise Armstrong, and many unidentified other observers. | Elimination of similar species: A Franklin's Gull juvenile or first-winter bird has a clear-cut blackish half-hood, a smaller bill, smaller size, and a white forehead. A juvenile Mew gull is much darker, has a thin bill, and light grayish legs. Juvenile Herring and California Gulls are much larger - larger than Ring-Billed Gulls - and lack the bright white at the base of the tail. | The original documentation form event lasted from approximately 09:00:00/09:15:00 and 11:00:00/12:10:00.

Other observers include Kay Niyo, Curt Nelson, Jan Walter, Chris Wood, and Jim Sandrock. | Elimination of similar species: [...] We saw this gull twice in our viewing time and debated if it was an adult Kumlien's Iceland Gull or an adult Thayer's Gull. It was an adult Kumlien's Iceland Gull because a Thayer's Gull has much more blackish coloration at the primary tips and more dark coloration at the primary tips than the Kumlien's which has grayish markings on the primary tips and less dark-colored markings at the primary tips overall. Also, a Kumlien's Iceland Gull shows the almost white wing tips like we saw with a little grayish markings on some primary tips. | The original documentation form event lasted from approximately 15:00:00/16:15:00.

The documentation form by Matthew Kenne is the only one submitted and forms the basis of this record. | Elimination of similar species: The lack of facial pattern and white throat and chest rule out peregrine, as the bird was flying almost directly into the sun (perpendicular to me). It wasn't as pale or brown as a prairie, and with shadow and distance there wasn't any dark/light pattern to the underwing. It wasn't black as a crow + the shape was wrong. Eagles were patterned and obviously larger. | The original documentation form event occurred around 13:10:00.
