After the breeding season, they keep very quiet and retired, like the rest of the waders, and the adults appear to slip quietly away without collecting into flocks, as soon as the young are able to take care of themselves. As soon as the young have assumed the complete fall plumage, that is about the 10th of August, they gather in large flocks with the other young waders, especially about the small ponds on the high land below Cape Smythe, and stay for several days before they take their departure for the South. Stray birds remain as late as the first week of September. On the New England coast the pectoral is both an early and a late migrant; a few adults sometimes appear in July and more come in August; but the main flight, mostly young birds, comes in September and October; they are often abundant in the latter month and I have seen them as late as October 31. When with us it is seldom seen on the sandy flats or beaches, but frequents the wet, fresh and salt meadows, preferably where the grass has been cut and which after a rain are covered with shallow pools of water. Here and along the margins of marshy creeks are its favorite feeding grounds. It does not decoy well and is no longer considered a game bird, but it has been popular with sportsmen for its gamy qualities and for the excellence of its flesh. There is a marked southeastward trend in the fall migration of this species; from its breeding grounds in northern Alaska and northeastern Siberia its main flight seems to be towards the Atlantic coast of the United States; it is not abundant and rather irregular on the Pacific coast south of Alaska; it is common at times in the interior of Canada and usually abundant in New England. It occasionally occurs in enormous numbers in Bermuda and seems to be always rare in Florida; these facts would seem to indicate an ocean route to South America. _Winter._--The winter home of the pectoral sandpiper is in southern South America. Arthur H. Holland (1891) says that in the Argentine Republic, it is "usually found in marshy land with long water weeds abounding, frequenting the same spot for weeks together." Between September and March 26, Doctor Wetmore (1926) recorded it as "fairly common" at various places in Paraguay, Argentina, and Uruguay. It evidently spends over half the year in its winter home and makes very rapid flights to and from its Arctic breeding grounds, where it makes a short visit of about two months. DISTRIBUTION _Range._--Northeastern Siberia, and North and South America; accidental in the Hawaiian Islands and the British Isles.
