Heavy-set shorebird with entirely black plumage and long, thick reddish bill. It has a distinctive fleshy red or yellow eye-ring and very thick pale-pink feet and legs. Exclusively coastal, where it can be found walking around on the edge of rocky headlands, on rock shelves, and along rocky beaches on small islands. Typically found in pairs or small groups. Its call is a loud slow whistled "chew", or when agitated a rapidly repeated "squeaky toy" call.
