Rallus

Genus of birds

Rallus is a genus of wetland birds of the rail family. Sometimes, the genera Lewinia and Gallirallus are included in it. Six of the species are found in the Americas, and the three species found in Eurasia, Africa and Madagascar are very closely related to each other, suggesting they are descended from a single invasion of a New World ancestor.[2]

Ridgway's rail (Rallus obsoletus)

These are slim, long-billed rails with slender legs. Their laterally flattened bodies are an adaptation to life in wet reedbeds and marshes, enabling them to slip easily through the dense semi-aquatic vegetation. Typically these birds have streaked brown upperparts, blue-grey on the face or breast, and barred flanks. Only the African rail has a plain back, and the plain-flanked rail lacks any blue-grey in its plumage and has no flank bars.[2]

Three endemic South American species are endangered by habitat loss, and the Madagascar rail is becoming rare.

Taxonomy

The genus Rallus was erected in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae.[3] The type species was subsequently designated as the water rail (Rallus aquaticus).[4] The genus name Rallus comes from the pre-binomial Latin name Rallus aquaticus for the water rail used by English ornithologist Francis Willughby in 1676,[5] and by the English naturalist Eleazar Albin in 1731.[6] The precise etymology of the word Rallus is uncertain.[7]

Species

The genus contains 14 extant species:[8]

  • Rallus lowei Madeira rail (prehistoric of Madeira)
  • Rallus montivagorum Pico rail (prehistoric of Pico Island in the Azores)
  • Rallus nanus São Jorge rail (prehistoric of São Jorge Island in the Azores) - erroneously previously described as Rallus minutus, which is a junior homonym[10]
  • Rallus natator (Pleistocene of San Josecito Cavern, Mexico) – formerly Epirallus
  • Rallus phillipsi (Late Pliocene of Wickieup, USA)

Formerly in Rallus

  • "R." arenarius – now Quercyrallus
  • "R." beaumontii, "R." dispar – now Pararallus or Palaeoaramides
  • "R." christyi, "R." eximius, "R." minor – now Palaeoaramides
  • "R." major – now Miorallus
  • "R." porzanoides – now Paraortygometra

"R." sumiderensis apparently refers to prehistoric remains of the Zapata rail (Cyanolimnas cerverai).
