| Occurrence Remarks |
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. |
