The Upland Sandpiper is an oddly proportioned sandpiper with a small head relative to its body. It feeds in the manner of plovers, walking rapidly for short distances and stopped abruptly to terrestrial insects. It is a long distance Boreal Migrant with its main wintering areas located in Argentina and Uruguay where it uses the prairies, wet grasslands, and hay fields of the pampas. Its migratory route takes it through the interior of South America, where it is often seen on Amazonian river bars, through Central America and Mexico and through the Great Plains from where it disperses across the northern Great Plains and breeds in similar habitats to its wintering grounds. It southward migration is largely the reverse.
