Cryptic shorebird found predominately in lowland wet grasslands and flooded fields. Note the long straight bill, white belly with variegated cryptic plumage, and prominent contrasting pale lines on the face and back. In flight, shows a white terminal tail band. Sings a fast repetitive “kek kek kek kek” when on the ground. Also listen for harsh and vibrating “drumming” notes that increase in volume, produced with its tail feathers during flight displays. Not restricted to Paraguay; widespread across much of South America. Formerly known as South American Snipe.
