Occurrence Remarks The documentation form by Ann Johnson is only one submitted and forms the basis of this record. Other observers include Mike Thomas. | Elimination of similar species: Although I understand the difficulty in identification of fall western sandpipers, the Baird's and white-rumped were eliminated because of wing length. The least sandpiper was eliminated by leg color and bill shape/size. The most difficult elimination was that of the semipalmateds, especially since other semipals were present in the area. After careful observation and comparison, however, the prototypical western sandpiper bill was too obvious to make the bird into a semipalmated. The bill was enough longer and had an obvious droop. The others in the area had varying bill sizes but none had the general shape of this bird. Consequently, I believe this was a late date western sandpiper. | The original documentation form event lasted from approximately 15:00:00/15:10:00.
