Rallus crepitans

, 1789,

Long Island, New York

.

In past, often treated as conspecific with R. longirostris, R. tenuirostris, R. obsoletus and R. elegans; more recently only with R. longirostris and R. obsoletus; but recent study#R indicates that each of these taxa merits recognition as a separate species, based largely on molecular evidence supported by morphological details, with present species intermediate in size, with the breast spanning a range of colours from very dull, silvery grey, to dull rufous, and breeding in saltmarshes, saltmeadows and mangroves; the (seemingly minor) differences are complex and require detailed evaluation both between and within current new species limits, but are provisionally accepted here in the light of genetic findings. Races grossi and belizensis sometimes lumped into pallidus; and leucophaeus into caribaeus. Proposed races manglecola (Antigua) and limnotis (Puerto Rico) included in caribaeus. Eleven subspecies recognized.

Subspecies and Distribution
  • R. c. crepitans J. F. Gmelin, 1789 – E USA from coastal Connecticut S to NE North Carolina.
  • R. c. waynei Brewster, 1899 – coastal S North Carolina to NE Florida.
  • R. c. saturatus Ridgway, 1880 – Gulf coast from SW Alabama to extreme NE Mexico (Tamaulipas).
  • R. c. pallidus Nelson, 1905 – coastal Yucatán, in SE Mexico.
  • R. c. grossi Paynter, 1950 – Quintana Roo (SE Mexico).
  • R. c. belizensis Oberholser, 1937 – Punta Ycacos Lagoon, in S Belize.
  • R. c. scottii Sennett, 1888 – coastal Florida (except NE).
  • R. c. insularum W. S. Brooks, 1920 – Florida Keys.
  • R. c. coryi Maynard, 1887 – Bahamas.
  • R. c. caribaeus Ridgway, 1880 – Cuba and Jamaica to Puerto Rico and Lesser Antilles E to Barbuda, also Guadeloupe and Martinique.
  • R. c. leucophaeus Todd, 1913 – I of Pines (SW Cuba).
  • Single individual recorded in NW Panama (Bocas del Toro) is thought to represent a hitherto undescribed form of either present species or R. longirostris#R#R.
