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.

The documentation form by Steve Dinsmore is the only one submitted and forms the basis of this record. Other observers include Andy Fix. | Elimination of similar species: see above [...] The bird was roughly 25% smaller than a Pectoral Sandpiper. [...] Note that we saw a single Semipalmated Sandpiper in the same flock of shorebirds. The Semipalmated Sandpiper had a shorter, thicker bill, more of a brown wash on the breast, and frequented the edge of the mudflat rather than wading in the water. | The original documentation form event lasted from 15:30:00/16:45:00.

The documentation form by Steve Dinsmore is the earliest and the one that forms the basis of this record. Anotther documentation form by Ross Silcock was submitted later. | Elimination of similar species: similar species eliminated above [...] This bird was slightly bigger than a Least and was much chunkier. The bird had dark legs, seen in direct comparison with the dark legs of Baird's Sandpipers and the yellowish legs of the Least Sandpipers. This bird was also still in basic plumage, making it much paler in color than the other peeps. [...] The bill was straight, dark, and much thicker at the base and the tip than the bill of a Baird's or Least sandpiper [sic]. | The original documentation form event lasted from 09:20:00/09:35:00.
