2 Semipalmated Sandpiper At the end of their Arctic breeding season, some Semipalmated Sandpipers fly up to 4,000 km (2,500 miles) non-stop from southeastern Canada and northeastern United States to their wintering grounds on the northern shores of South America, 1 with flocks of up to 300,000 individuals gathering at key stopover and wintering sites. Semipalmated Sandpipers winter mostly in South America, and studies have shown that they may make a non-stop flight of nearly 2000 miles from New England or eastern Canada to the South American coast. The Semipalmated Sandpiper gets its common name from the short webs between its toes ("palmated" means webbed). 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. Semipalmated Sandpipers use different routes for northward and southward mi- gration. An abundant small shorebird, the Semipalmated Sandpiper breeds in the Arctic and winters along the coasts of South America. Small and plain in appearance, this sandpiper is important in terms of sheer numbers.

Three Semipalmated Sandpiper populations breed in northern Canada and in Alaska in the United States: the western (Alaska) population represents about 64% of the population, while the central (western Canadian Arctic) and eastern (eastern …
