Six species of Rails and Crakes have been recorded in Galapagos: 3 resident species and 3 vagrant species. The only endemic species is the Galapagos Rail. Rails and crakes are small to medium-sized ground-dwelling birds with plump bodies; short tails, which are often held erect; shortish necks and bills; and long legs and toes (the feet are not webbed). They are generally rather furtive, mainly inhabiting marshy areas and are usually reluctant to fly. They are good swimmers. The sexes are alike in all species.
