The Sanderling is one of the most widely spread of all the Arctic
Grallæ during its winter migration. Durnford obtained examples at Tombo
Point, Central Patagonia, on the 30th December, 1877, so that it must
necessarily pass through the Argentine Republic. It is only known to
breed in the high Northern Polar lands.
