The Stilt Sandpiper, Calidris himantopus, is a small shorebird; it bears some resemblance to the smaller calidrid sandpipers or “stints.” The Stilt Sandpiper breeds in the open arctic tundra of North America. It is a long-distance migrant, wintering mainly in northern South America. Breeding adults are distinctive, heavily barred beneath, and with reddish patches below and behind the eye. The back is brown with darker feather centres. Winter plumage is basically gray above and white below.
