The Upland Sandpiper is a black, brown, and white mottled bird with a long neck and tail and yellow legs. It has a round head with large, black eyes, and a relatively short bill for a sandpiper. In flight, it shows a pale inner wing, dark outer wing, and white outer primary shaft

Native grassland is the Upland Sandpiper's preferred habitat. It typically feeds in shortgrass areas, where it is found in migration and during winter. The Upland Sandpiper requires taller grass for nesting. It is almost never found on mudflats or in wetland environments where other shorebirds are found. These birds are common nesters at airfields and airports throughout their range.

The Canadian Wildlife Service estimates the Upland Sandpiper population at about 350,000 birds. Most of the population is concentrated in the Great Plains, where they are still common. In both the northeastern and northwestern portion of their range, Upland Sandpipers have become far less common. Although they were probably never abundant in the Northwest, they formerly bred widely in eastern Washington. With the loss of native grassland habitat, the Northwest population has now dwindled to a few small, isolated populations. The last remaining Washington population, near Spokane, is most likely extirpated. With the Spokane population gone, a small population in Idaho, another group in Montana, and a few dozen pairs in Oregon are the only breeding Upland Sandpipers that remain in the Northwest. The Upland Sandpiper is still listed as a state endangered species and a Gap Analysis species-at-risk.

Upland Sandpipers eat mostly insects, but also feed on waste grains and other seeds.

This species has a large range, with an estimated global Extent of Occurrence of 3,300,000 km². It has a large global population estimated to be 350,000 individuals (Wetlands International 2002). Global population trends have not been quantified, but the species is not believed to approach the thresholds for the population decline criterion of the IUCN Red List (i.e. declining more than 30% in ten years or three generations). For these reasons, the species is evaluated as Least Concern. [conservation status from birdlife.org]

Upland Sandpipers may nest in loose colonies, in which case the colony has a highly synchronous nesting pattern, meaning that all the chicks hatch at the same time. Nests are shallow scrapes on the ground in dense grass. They are often well hidden from above with grass arching over the top. Both parents help build the nest and incubate the 4 eggs for 22 to 27 days. The young leave the nest shortly after hatching and, while the young feed themselves, the parents protect and tend them. The young first fly at 30 to 31 days.

Long distance migrant. Main wintering areas seem to be located in Argentina and Uruguay. Migrates through Great Plains, Mexico, Central America, across Gulf of Mexico and most of South America E of Andes; some movement across W Atlantic; no evidence of Atlantic crossing during northward migration. Leaves breeding areas late Aug to early Sept, arriving in non-breeding areas late Sept to Oct; return passage starts mid-Feb, birds reaching breeding grounds early Apr to Jun.
