The Clapper Rail (Rallus longirostris) is a member of the rail family, Rallidae. Some researchers believe that this bird and the similar King Rail are a single species; the two birds are known to interbreed.

Distribution and habitat[edit]

The Clapper rail and its subspecies are found along the Atlantic Ocean and Pacific Ocean]] coasts and several inland locales of the Americas.

Atlantic[edit]

The clapper rail is found along the Atlantic coasts; of the U.S. East Coast, Gulf of Mexico, Eastern Mexico, and some Caribbean islands, and south through eastern Central America to Northern South America and Northeastern Brazil.

Populations are stable on the East Coast of the U.S. — although the numbers of this bird have declined due to habitat loss.

Pacific[edit]

The clapper rail is found along the Pacific Coasts; from central California and western Arizona, south through Western Mexico and western Central America, to coastal Ecuador and northern Peru.

Despite this wide range, numbers of the Clapper Rail are now very low on the West Coast of the United States, because of significant destruction of coastal marshland and estuary habitats from urbanization.

Description[edit]

The Clapper Rail is a chicken-sized bird that rarely flies. It is grayish brown with a pale chestnut breast and a noticeable white patch under the tail. Its bill curves slightly downwards. The Trinidadian subspecies R. l. pelodromus is more heavily marked with black above.

Behaviour[edit]

Feeding[edit]

These birds eat crustaceans, aquatic insects, and small fish. They search for food while walking, sometimes probing with their long bills, in shallow water or mud.

Breeding[edit]

The twig nest is placed low in mangrove roots, and 3-7 purple-spotted buff eggs are laid.
