Pluvianellus sociabilis; Print; Magellanic plover; The Magellanic plover (Pluvianellus socialis) is a rare and unique wader found only in southernmost South America. It was long placed in with the other plovers in the family Charadriidae; however; behavioural evidence suggested they were distinct; and molecular studies confirmed this; suggesting that they are actually more closely related to the sheathbills; a uniquely Antarctic family. As such it is now placed in its own family; Pluvianellidae. This species is not a long-distance migrant; although some birds move further north in southern Argentina in winter. The species breeds inland and then moves to the coast during the winter; particularly to estuaries.; 1820-1860
