Bonaparte's Sandpiper is a third of the same category of Arctic _Tringæ_
that range far south after the breeding-season. Durnford found it
common "in flocks" near Buenos Ayres, and again in the valley of the
Sengel river in Central Patagonia in winter. White and Hudson also
obtained specimens near Buenos Ayres, and Barrows in Entrerios near
Concepcion.
