The Upland Sandpiper primarily breeds in a range that stretches from southern Canada to the central United States, encompassing the areas from the Rocky Mountains to the Appalachian Mountain region.

Identification

The Upland Sandpiper is characterized by its long legs, slender neck, small dove-like head with large eyes, and a yellow bill with a black tip. It has a long tail and wings, with the tail being proportionately the longest among sandpipers. Its upper parts display marbled golden brown and blackish patterns, while the underparts are white with dark streaks and chevron-shaped markings on the breast and sides. Juvenile Upland Sandpipers resemble adults but lack the distinct dark crown on the head, and feathers on their upperparts have prominent pale margins and dark subterminal bars, which are absent in adults. Females are slightly bigger than males. 

The Upland Sandpiper adopts a unique wing posture when perching or landing, holding wings erect before folding. During the breeding season, males perch on fence posts and engage in graceful circular song flights over their territory. They migrate in groups during the night, and after their eggs hatch, family groups can be observed foraging together.

Displaying males sing a distinctive long mellow “wolf whistle” call, often heard at night. The sandpiper also emits a rapid fluttering series of tu or pip notes, commonly heard during flight or in contact with others.

Habitat

The Upland Sandpiper primarily nests in grasslands, with a preference for native prairies in the Great Plains. However, they also utilize other habitats for nesting, including pastures (both grazed and ungrazed), agricultural fields (especially fallow fields), and even road edges. These grassland habitats are characterized by minimal woody vegetation and bare ground. In eastern North America, they can be found in habitats such as blueberry barrens, peatlands, and airports. During migration, they frequent airfields, agricultural fields, and pastures, but they can also be found at beaches or ballfields, especially during unfavorable weather conditions.

Threats to Conservation

The Upland Sandpiper faces several threats to its conservation due to the loss of habitat to agriculture, including the use of pesticides and farming practices that leave less residual crop. The initial conversion of land for crop cultivation and the plowing of grasslands have had a significant negative impact. Furthermore, habitat alteration caused by urban development, invasive species, and changes in vegetation structure further diminishes suitable nesting areas. Disturbance to pastures and hayfields and extensive row-cropping are additional factors contributing to population declines. 

Other threats include wildfires that destroy habitat and prevent its recovery, as well as spring heat waves that endanger the young birds in the nest.
