The taxonomy for this species is confusing and still being determined. The Ridgway's rail and the mangrove rail have been recently split. 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. Distribution and habitatThe clapper rail is found along the Atlantic coasts of the eastern U.S., Gulf of Mexico, eastern Mexico, some Caribbean islands, and south through eastern Central America, as well at several inland locales. Populations are stable on the East Coast of the U.S., although the numbers of this bird have declined due to habitat loss. SubspeciesCurrently named subspecies of the clapper rail (Rallus crepitans) include:[2][3]
DescriptionThe 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. BehaviourFeedingThese 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. BreedingThe twig nest is placed low in mangrove roots, and 3-7 purple-spotted buff eggs are laid. References
