The differences between this Pectoral Sandpiper and its close ally the Siberian Pectoral 

 Sandpiper have been already pointed out. 



The American form of the Pectoral Sandpiper is probably confined to Arctic America 

 during the breeding-season. It breeds abundantly near Point Barrow in Alaska, and has 

 occurred as far east as Greenland. It passes through the United States on migration, 

 and regularly visits the Bermuda Islands, sometimes in enormous flocks (Reid, Zoologist, 

 1877, p. 477). It winters in Mexico, the West Indies, Central America, and probably 

 throughout South America. Buckley obtained it in Bolivia (Sclater & Salvin, Proc. Zool. 

 Soc. 1879, p. 641), Reed in Chili (Sclater & Salvin, Proc. Zool. Soc. 1873, p. 455), and 

 Durnfordin Northern Patagonia (Ibis, 1877, p. 43). I have examples collected by Bartlett 

 in Eastern Peru, and it has occurred in various localities in Brazil.
