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 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.

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.

We also listened to "A Field Guide to Bird Songs" and although the Sharp-shinned recording was that of 175 "kek-kek-kek" warning/alarm call, the Cooper's Hawk recording was that of a food begging call which was very similar but of a significantly lower pitch than that of the bird we observed. | The original documentation form event lasted from 14:30:00/14:31:00.
