The documentation form by Thomas H. Kent is the earliest and the one that forms the basis of this record. Another documentation form by Peter C. Petersen was submitted later. Other observers include Dan Dorrance and many unidentified observers. | Elimination of similar species: The overall size, head size, bill size, and lack of dipped-in-ink effect on the bill tip exclude Glaucous Gull. I excluded Thayer's Gull because both of these birds had very light primaries (not dark webs on the outer primaries). Neither had a secondary bar or in fact any distinctive marking on the wings. The lack of tail band in the first year bird also excludes Thayer's Gull. I was impressed by the paleness of the gray mantle in the second-year bird, but have too little experience with older Thayer's Gulls to make a comparison. | The original documentation form event lasted from 11:30:00/12:30:00.

The documentation form by Francis L. Moore is the only one submitted and forms the basis of this record. Other observers include Russell Hays, Tom Kent, Tom Shires, Tom Staudt, and many unidentified other observers. | Elimination of similar species: Ring-billed Gull and Herring Gull, see above. The Ring-billed Gulls were seen in direct contrast to these three birds and were definitely much smaller birds. The Herring Gulls (first year birds) that I have seen have more of a contrast between the rump and back and upper wing surfaces and none that I remember showed the whitish trailing edge on the tail. [...] The three birds seen were about the size of Herring Gulls in typical first year plumage. They were obviously large gulls of the genus Larus with a noticeably larger size than the Ring-billed Gulls and one Bonaparte's Gull that were next to the three larger birds. [...] There were no Herring Gulls nearby with which to make a comparison of size and coloration. The bills of all three gulls were black did not seem as heavy or bulky as the bill of a Herring Gull. | The original documentation form event lasted from 08:10:00/09:30:00.
