Fidelity of individual shorebirds to stopover sites between years has been documented in only a few species. In May 2005, we recaptured a migrant male Western Sandpiper (Calidris mauri) on the Copper River Delta, Alaska, 5.8 km from its original 2004 capture site. We classified the individual as a first-year bird in 2004 and as an adult in 2005. This report extends our knowledge of site fidelity in migrant shorebirds to one of the most common species on the west coast of North America, and to a small geographic area within a larger stopover site.
