Occurrence Remarks The documentation form by Thomas H. Kent is the earliest and the one that forms the basis of this record. Other documentation forms by Jim Fuller, Chris Edwards, Jim Dinsmore, Stephen J. Dinsmore, and Mark Proescholdt were submitted later. Other observers include Kevin Healy, Dick Tetrault, Reid Allen, Pam Allen, Eloise Armstrong, Eugene Armstrong, Beth Proescholdt, Kay Niyo, Eric Haley, and Hank Zaletel. | Elimination of similar species: The size and thick bill exclude Red-throated and Pacific Loons. The features that favor Yellow-billed over Common Loon include the bill shape, dark line to mid culmen, small eye, auricular patch, and the pattern of the foreneck and face (little extension of white and mottled color). The back pattern (wavy white lines rather than fuzzy white lines with dark bars) and paleness of the auricular patch indicate a juvenile. | The original documentation form event lasted from 07:45:00/09:00:00.
