An abundant small shorebird, the Semipalmated Sandpiper breeds in the Arctic and winters along the coasts of South America.
Semipalmated Sandpipers from eastern populations probably undertake nonstop transoceanic flights of 3,000 - 4,000 km (1,900 - 2,500 mi) from New England and southern Canada to South America, powered by extensive fat reserves. The Semipalmated Sandpiper gets its common name from the short webs between its toes ("palmated" means webbed). The Western Sandpiper is the only other small sandpiper with similarly webbed toes.
