They live mainly in salt marshes but also can be found in the brackish marsh and mangrove swamps. All rails are grouped in the order Gruiformes which contains six families including Cranes and such oddities as Limpkins and Sun Bitterns. (2019). Furthermore, some taxonomists consider that the King rail and Aztec rail should be considered within this group, as those birds look similar and the birds are known to interbreed where they share territories. Clapper Rails are threatened by habitat development and degradation, and high tides associated with storms. Habitat and Ha bi ts Clapper rails are found almost exclusively in coastal saltwater marshes. Clapper rails live in saltmarshes with extensive vegetation, which they use as refuges, especially at high tide. Alfred A. Knopf, New York, NY, USA.
