Coots Rails and Moorhens: Rallidae - Conservation Status

Of the 134 rail species in existence, thirty-three are considered threatened by the World Conservation Union (IUCN). Of these, four are Critically Endangered, facing an extremely high risk of extinction in the wild. Twelve are Endangered, facing a very high risk of extinction, and sixteen are Vulnerable, facing a high risk of extinction. One, the Guam rail, is Extinct in the Wild. No fewer than twenty rail species have become extinct since 1600, the majority of them flightless species on islands. Threatened species have suffered population declines due primarily to habitat destruction. Some island species have also been severely affected by the introduction of animals such as cats, dogs, pigs, mongooses, and snakes.
