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 Duefias, 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 Scolopacide frequent the inundated land, of which H. maculata
