The clapper rail (Rallus crepitans) is a member of the rail family, Rallidae. The taxonomy for this species is confusing and still being determined. It is a large brown rail that is resident in wetlands along the Atlantic coasts of the eastern United States, eastern Mexico and some Caribbean islands. This species was formerly considered to be conspecific with the mangrove rail.
The clapper rail was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with all the other rails in the genus Rallus and coined the binomial name Rallus crepitans.[2] Gmelin based his description on those by Thomas Pennant and John Latham.[3][4] The type locality is Long Island, New York.[5] The genus Rallus had been erected in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae.[6] The specific epithet crepitans is Latin meaning "breaking wind" or "resounding".[7]
The clapper rail was formerly treated as a subspecies of the mangrove rail (Rallus longirostris).[5] The decision to treat the clapper rail as a separate species was based on the results of a molecular phylogenetic study that was published in 2013.[8][9][10] A cladogram based on the 2013 genetic study is as follows:[8]
Virginia rail (Rallus limicola)
Ridgway's rail (Rallus obsoletus)
Aztec rail (Rallus tenuirostris)
Mangrove rail (Rallus longirostris)
King rail (Rallus elegans)
Clapper rail (Rallus crepitans)
Eight subspecies of the clapper rail are recognised:[10]
The clapper rail is a chicken-sized bird that rarely flies. It is grayish brown with a pale chestnut breast. Males and females have similar plumage. The bill which curves slightly downwards is orange yellow at the base in males and duller in females. An adult bird has an overall length of 32–41 cm (13–16 in) and weighs 199–400 g (7.0–14.1 oz).[11]
The clapper rail is found along the Atlantic coasts of the eastern U.S., the 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. Clapper rails are saltmarsh specialists, and are highly mobile across their range, with females showing weak philopatry and a lack of philopatry in males.[12]
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.[11]
The nest is a large platform of dry grasses and is usually placed on the ground in dense vegetation. The clutch size varies between 4 and 16 eggs with an average of 9. The eggs measure 42.5 mm × 30 mm (1.67 in × 1.18 in) and are creamy white with irregular blotches of reddish-brown, grey or lilac. They are incubated for 20 days by both parents with the male incubating at night. The young are brooded by the adults for several days. They become independent of the adults when 6 weeks old and can fly when 10 weeks old.[11]

El rascón crepitante (Rallus crepitans)[2] también conocido como rascón costero del atlántico,[3] gallinuela de manglar o pollo de manglar,[4] es una especie de ave gruiforme de la familia Rallidae propia de Norteamérica y el Caribe.
Se reconocen las siguientes subespecies:[5][6]
Es un ave del tamaño de un pollo que rara vez vuela, mide aproximadamente 36 cm de longitud y tiene un peso entre 200 y 400 gramos.[2] Es de color marrón grisáceo con el pecho castaño pálido y una mancha blanca notable debajo de la cola. Su pico se curva ligeramente hacia abajo.
Se distribuye a lo largo de las costas atlánticas del este de los Estados Unidos, el Golfo de México, el este de México, algunas islas del Caribe y América Central, así como en varios lugares del interior.
Las poblaciones se mantienen estables en la costa este de los Estados Unidos, aunque el número de esta ave ha disminuido debido a la pérdida de hábitat.
Se alimentan de crustáceos, insectos acuáticos y pequeños peces. Buscan comida mientras caminan, a veces sondeando con sus picos en agua poco profunda o barro.

Rallus crepitans
Le Râle tapageur (Rallus crepitans) est une espèce d'oiseaux de la famille des Rallidae, jadis regroupée en une seule espèce avec le Râle gris (R. longirostris).
Cet oiseau fréquente le littoral est/sud des États-Unis, des Antilles et de la péninsule du Yucatán.
Selon le Congrès ornithologique international (version 5.1, 2015)[1] et Alan P. Peterson[2], il existe huit sous-espèces :

Il rallo battente (Rallus crepitans J. F. Gmelin, 1789) è un uccello della famiglia dei Rallidi, diffuso nel continente americano[2].
Questo rallide misura circa 36 cm di lunghezza e ha un peso compreso tra 200 e 400 g[3].
Si nutre principalmente di molluschi (cozze, vongole, lumache), artropodi, vermi e piccoli pesci[3].
Questa specie è diffusa nelle aree costiere degli Stati Uniti sud-orientali, del golfo del Messico, dell'America centrale, e di numerose isole caraibiche tra cui Anguilla, Antigua e Barbuda, Bahamas, Barbados, isole Cayman, Cuba, Dominica, Guadalupa, Haiti, Giamaica, Martinica, Montserrat, Saint Kitts e Nevis, Saint Lucia, Saint Vincent e Grenadine, Turks e Caicos, e isole Vergini[1].
Popola paludi, lagune salmastre e mangrovie, sempre in prossimità delle coste[3].
Sono note le seguenti sottospecie[2]:

De klapperral (Rallus crepitans) is een vogel uit de familie van rallen (Rallidae).
Deze soort komt voor in Noord-, Midden- en Zuid-Amerika en telt 21 ondersoorten:
Kustrall[2] (Rallus crepitans) är en amerikansk fågel i familjen rallar inom ordningen tran- och rallfåglar.[3]
Kustrall delas in i elva underarter i fyra grupper:[3]
Underarterna grossi och belizensis inkluderas ofta i pallidus, medan leucophaeus ofta inkluderas i caribaeus.[4]
Tidigare betraktades mangroverall (R. longirostris) och ridgwayrall (R. obsoletus) ingå i kustrall, då under det vetenskapliga namnet Rallus longirostris. Genetiska, morfologiska och ekologiska studier visar dock att de är tre olika arter.[5]
Arten har ett stort utbredningsområde och en stor population, men tros minska i antal, dock inte tillräckligt kraftigt för att den ska betraktas som hotad.[1] IUCN kategoriserar därför arten som livskraftig (LC).[1]
