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 Pam and Reid Allen is the earliest and the one that forms the basis of this record. Other documentation forms by Mark Proescholdt, Thomas H. Kent, Phil Walsh, and Michael D. Overton were submitted later. Other observers include Jim Sinclair, Ann Johnson, Eugene Armstrong, Dixie Overton, Cal Knight, Bernie Knight, and Eloise Armstrong. | Elimination of similar species: The Western Grebe (Aechmorphorus occidentalis) has a much duller, greyish-greenish yellow bill and the body and flanks are blacker. Plus, the black cap extends over the eyes and lores, and there is a more solid blackish cast on the bill. | The original documentation form event lasted from 12:15:00/14:10:00.
