| Occurrence Remarks |
The documentation form by Ann M. Barker forms the basis of this record. Other documentation forms by Jim Fuller, Peter C. Petersen, Thomas H. Kent, Gerald White, Tanya E. Bray, Ross Silcock, Carl Bendorf, and Michael J. Baum were submitted. Other observers include Mary Lou Petersen, Cal Knight, Bernie Knight, Tom Rockwell, Lewis Blevins, Brian Blevins, Don Moeller, Walter Zuurdeeg, Daryl Tessen, Doug Rose, Alan Grenon, and many unidentified observers. | Elimination of similar species: (A) Greater black backed - Gull in question has slaty - gray saddle rather than coal black. And Gull in question is same size as Herring Gulls; Greater black-backed would be much larger. (B) Lesser black backed - Gull in question has pink legs and feet, and has much more white on primaries. (C) Western - Gull in question has considerable white on primaries, and does not show dusky trailing edge to underwing. Also has broader white trailing edge to upperwing than would the Western. (D) Herring Gull - dark race - no experience with this, but those shown in Harrison do not show as dark a saddle as Gull in question, nor as much white on primaries. | The original documentation form event lasted from 15:00:00/15:30:00 on February 12, 1989, 12:15:00/12:45:00 and 16:00:00/17:30:00 on February 14, 1989. |
