The Crab-plover or Crab Plover (Dromas ardeola) is a chicken relevant to the waders, but completely exclusive to advantage its own household Dromadidae. Its connection within the Charadriiformes is not yet determined, some have regarded it to be carefully relevant to the thick-knees, or the pratincoles, while others have regarded it better the auks and gulls. It is the only associate of the genus Dromas and is exclusive among waders in using floor comfort to aid incubation of the egg.
