This lively, social little Sandpiper is common throughout America, nesting in the Arctic regions. It is migratory, arriving the last of March to the first of May, a few occasionally remaining till November. It has been found breeding as far south as Sable Island, Nova Scotia, but its usual breeding grounds are north from Labrador and Alaska to Greenland, wintering from California and the Gulf states southward. It is more restless and active than the larger Sandpipers, but in habits it differs little, if any, from them. It runs nimbly about, often with the large waders, feeding around and beneath them, apparently heedless of danger. While watching the birds, they will often pass close to the feet, but at the least motion the whole flock will spring into the air "like a flash, with a startled _Peep, peep_, and in a compact form swiftly sweep about in an uncertain manner, canting from side to side, showing rapidly the white beneath and the dark above, a wavy, pretty sight, the white at times fairly glistening in the sunlight." When migrating or going any distance their flight is steady and direct. Audubon, who observed the breeding habits of the birds in Labrador, says that at all periods, excepting those at which they have nests containing eggs, or young so small and feeble as to require all the care of their parents, the flight of this species resembles that of the Common Snipe (see BIRDS, Vol. IV., page 7); but when started from the nest, or from any place in the immediate vicinity, it rises and moves off low over the ground, with deeply incurved wings, and with a whirling motion thereof, which, if as rapid as those of a Partridge, would appear quite similar, but on such occasions the Lesser Sandpiper moves slowly, and instead of uttering the note of independence, as it were, which it emits at other times, while freely and fearlessly traveling, it gives out sounds weakened by grief or anxiety, for the purpose of inducing the observers to follow it. If on the ground, it acts in a similar manner, moves off slowly, and limping as if crippled, and this at times quite as much as if one had come upon it while on its nest, or surprised it with its young. The Sandpiper's nest is placed on the ground in a slight depression, scantily lined with leaves and grasses. The eggs are three or four, of ground color cream buff to light drab, spotted and blotched irregularly with varying shades of brown, thickest about the larger end.
