Upland sandpipers
forage in fields, picking up food by sight. They are frequently sighted on fence posts and even telephone poles. When an "uppy" alights, it holds its wings up for a few seconds. They are constantly scanning the horizon for intruders. The upland sandpiper's diet includes grasshoppers,
crickets,
weevils, beetles,
moths,
ants, flies,
bugs,
centipedes,
millipedes, spiders, snails, and earthworms. It also eats some grains and seeds. Every year, between September and October, some upland sandpipers migrate to
Ozogoche lagoons, in southern
Ecuador. Hundreds of them swoop down and dive into the icy waters of the lagoons, where they die of
hypothermia. The explanation for this behavior is uncertain.
Breeding Upland sandpipers can sometimes be found in small, loose nesting colonies. The breeding season is from early-to-late summer;
nests are located on the ground in dense
grass. The female lays 4 eggs. Both parents look after the young and may perform distraction displays to lure predators away from the nest or young birds.
Call Upland sandpipers can be identified by a distinctive call, sometimes called a "wolf whistle", which features a long, ascending whistle followed by a second rising and/or falling call. These sounds are often made while the bird is landing or while flying high. ==Conservation==
