Occurrence Remarks The documentation form by Steve Dinsmore is the one that forms the basis of this record. Other documentation forms by Jim Dinsmore, Bob Myers, Robert Cecil, Ann Johnson, Jim Fuller, Michael K. Thomas, and Mark Proescholdt were submitted. Other observers include Dennis Thompson, Betsy Myers, Eugene Armstrong, Eloise Armstrong, and many unidentified observers. | Elimination of similar species: The large size should eliminate all peeps. The bird was also larger than Sanderlings in direct comparison. Otherwise, the bill shape and dull yellow legs would eliminate Sanderling and Dunlin. | The original documentation form event lasted from 06:53:00/07:41:00 and 08:15:00/09:35:00.
Occurrence Status present
Field Number 1989-32
