Semipalmated Sandpiper (Calidris pusilla), Willcox, Twin Lakes, Apache County

This Semipalmated Sandpiper was discovered and photographed by Chet McGaugh on 25 July 2012.

Semipalmated Sandpiper is a rare fall migrant.A rare, but regular, fall transient in Arizona.  Usually associates with other peeps. 

The short, straight bill, black legs, the lack of heavier black streaking or chevrons on the lower flanks, the short wing projection, and the lack of rufous edging on the back, scapulars, crown, and ear coverts all point to Semipalmated and away from any of the similar species. Worn feathers indicate this is an adult.
