The Pectoral Sandpiper breeds in the Arctic Regions of North America and migrates 

 along both coasts of Central America to its winter home in the southern continent, 

 reaching even as far south as Patagonia. 



At Matamoros, Mr. Dresser noticed the species in July, so that it appears to start 

 on its southern journey as soon as the breeding-season is over. He says that it 

 did not frequent the lagoons, but was found on the banks of the Rio Grande or at 

 small pools after rain. Salvin states that at Duenas, in Guatemala, about the 

 beginning of April, and towards the end of the dry season, a great part of the stream 

 is diverted from the river Guacalate to irrigate the pastures, and that during this 

 period numbers of Scolopacidse frequent the inundated land, of which H. maculata
