Distinctive sandpiper found in areas with short grass. Frequently seen perched on fence posts or atop small shrubs. Overall patterned buffy-brown with small head, long neck, large eye, and yellow bill with black tip. Long tail and shallow fluttery wingbeats give it a unique look in flight. Song typically given in flight; starts with a soft gurgling trill and ends with a loud whistle that rises and falls. Migrates to South America in the winter, particularly Paraguay and northern Argentina.
