Verbreitung und Lebensraum

Even though they are sandpipers, they prefer open country with tall grasses to coastal habitat. They are also found at airports, blueberry farms and abandoned strip mines in the east. Their true core range and habitat is in the northern midwest United States. They breed from eastern Alaska south east of the Rocky Mountains through Montana to northern Oklahoma and then northeast to Pennsylvania, New England and extreme southern Quebec and Ontario. There are also local breeding populations in northeast Oregon and west central Idaho. They winter in northeastern Argentina, Uruguay and southern Brazil. It is an extremely rare vagrant to the South Pacific, with one record each from Australia and New Zealand.

Schutzstatus

The numbers of these birds increased as forests were cleared in the early 19th century, but declined sharply in the late 19th century due to hunting. They are now regularly present in Midwestern North America but populations are scattered in the east.<p>Loss of prairie habitat is a concern. Also, livestock grazing has been found to reduce the number of nests in a field. Controlled burns may benefit this species as they feed on low-growing plants that are more easily spotted after a fire.
