During migration months (April-May & August-September), these birds are commonly spotted along coastal areas in California, Oregon, Washington State, Mexico’s Baja Peninsula all through South America.


These shorebirds prefer wet habitats like marshes or estuaries where they can feed on invertebrates like crustaceans or mollusks buried deep within sediments at high tide marks.
