Dromas

The crab-plover or crab plover (Dromas ardeola) is a coastal wader (shorebird). It is the only member of the genus Dromas and the family Dromadidae. It is unique among waders in making use of ground warmth to aid the incubation of its eggs. The crab-plover is classified in the suborder Lari, making it more closely related to gulls and auks than to most other waders such as plovers (suborder Charadrii) and sandpipers (suborder Scolopaci).
