In the interior this species is commoner than it is on the Atlantic coast. Mr. Harrold says that in Manitoba it is fairly common in the fall, adults being noted as early as July 5; the young birds are usually with the lesser yellow-legs in the fall. Mr. Hersey collected a series for me in Manitoba between July 18 and 29, 1913. Stilt sandpipers were formerly sold in the markets, mixed with bunches of summer yellow-legs, but their sale is now prohibited, and they are too small to be considered as game birds. _Winter._--The winter home of the stilt sandpiper seems to be in southern South America, Argentina, Paraguay, Uruguay, and Chile, but actual records substantiated by specimens are not numerous. Ernest Gibson (1920) shot some "out of a flock of over 100" which "might easily have been 200, so closely were they massed." They "were feeding on marshy ground; and as the flock rose at" his "approach, circled and passed away, the white under surfaces were quite dazzling in the sunlight." This was near Cape San Antonio, Buenos Aires, on December 27, 1913. Dr. Alexander Wetmore (1926) writes: The stilt sandpiper was encountered only in the Chaco, west of Puerto Pinasco, Paraguay, though it has been said that it is common in some parts of the Province of Buenos Aires in winter. At kilometer 80, on September 20, 1920, the first arrivals, a flock of a dozen, were recorded at the border of a lagoon; as I watched they rose suddenly to whirl rapidly away to the southward. On the following day about 20 were seen, and an adult female was taken. At Kilometer 170, on September 24, a small flock passed down the nearly dry channel of an alkaline stream known as the Riacho Salado, while at Laguna Wall (kilometer 200) about 30 were seen September 24, and 40 on the day following. The birds were found in little flocks, often mingled with other waders that walked or waded through shallow water on muddy shores where they probed with their bills for food. DISTRIBUTION _Range._--North America, south to southern South America. The stilt sandpiper is one of the rarer shore birds and but little is known of its range and migrations. _Breeding range._--North to probably northeastern Alaska (Demarcation Point); probably Yukon (Herschel Island); Mackenzie (Fort Anderson, Rendezvous Lake, Franklin Bay, and probably Kogaryuak River); and probably Keewatin (Cape Eskimo). East to probably Keewatin (Cape Eskimo); and probably Manitoba (Fort Churchill and York Factory). South to probably Manitoba (York Factory); and Mackenzie (Artillery Lake). West to Mackenzie (Artillery Lake); and probably Alaska (Demarcation Point). Eggs have been taken only in northern Mackenzie.
