The Anatidae are the biological family of water birds that includes ducks, geese, and swans. The family has a cosmopolitan distribution, occurring on all the world's continents except Antarctica. These birds are adapted for swimming, floating on the water surface, and in some cases diving in at least shallow water. The family contains around 174 species in 43 genera.
Rails are a large, cosmopolitan family of small- to medium-sized terrestrial and/or semi-amphibious birds. The family exhibits considerable diversity in its forms, and includes such ubiquitous species as the crakes, coots, and gallinule; other rail species are extremely rare or endangered. Many are associated with wetland habitats, some being semi-aquatic like waterfowl, but many more are wading birds or shorebirds. The ideal rail habitats are marsh areas, including rice paddies, and flooded fields or open forest. They are especially fond of dense vegetation for nesting. The rail family is found in every terrestrial habitat with the exception of dry desert, polar or freezing regions, and alpine areas. Members of Rallidae occur on every continent except Antarctica. Numerous unique island species are known.
Junglefowl are the only four living species of bird from the genus Gallus in the bird order Galliformes, and occur in parts of South and Southeast Asia. One of the species in this genus, the red junglefowl, is of historical importance as the direct ancestor of the domestic chicken, although the grey junglefowl, Sri Lankan junglefowl and green junglefowl are likely to have also been involved. The Sri Lankan junglefowl is the national bird of Sri Lanka. They diverged from their common ancestor about 4–6 million years ago. Although originating in Asia, remains of junglefowl bones have also been found in regions of Chile, which date back to 1321–1407 CE, providing evidence of possible Polynesian migration through the Pacific Ocean.
Larus is a large genus of gulls with worldwide distribution.
The woodcocks are a group of seven or eight very similar living species of wading birds in the genus Scolopax. The genus name is Latin for a snipe or woodcock, and until around 1800 was used to refer to a variety of waders. The English name is first recorded in about 1050. According to the Harleian Miscellany, a group of woodcocks is called a "fall".
Coots are medium-sized water birds that are members of the rail family, Rallidae. They constitute the genus Fulica, the name being the Latin term for "coot". Coots have predominantly black plumage, and—unlike many rails—they are usually easy to see, often swimming in open water.
The water rail is a bird of the rail family which breeds in well-vegetated wetlands across Europe, Asia and North Africa. Northern and eastern populations are migratory, but this species is a permanent resident in the warmer parts of its breeding range. The adult is 23–28 cm (9–11 in) long, and, like other rails, has a body that is flattened laterally, allowing it easier passage through the reed beds it inhabits. It has mainly brown upperparts and blue-grey underparts, black barring on the flanks, long toes, a short tail and a long reddish bill. Immature birds are generally similar in appearance to the adults, but the blue-grey in the plumage is replaced by buff. The downy chicks are black, as with all rails. The former subspecies R. indicus, has distinctive markings and a call that is very different from the pig-like squeal of the western races, and is now usually split as a separate species, the brown-cheeked rail.
The clapper rail 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.
Anas is a genus of dabbling ducks. It includes the pintails, most teals, and the mallard and its close relatives. It formerly included additional species but following the publication of a molecular phylogenetic study in 2009 the genus was split into four separate genera. The genus now contains 31 living species. The name Anas is the Latin for "duck".
The Ibiza rail is a recently discovered fossil species of rail, described from a late Pleistocene to Holocene cave deposit at Es Pouàs, on the island of Ibiza. Ibiza is in the Pityuses group of the Spanish Balearic Islands in the Mediterranean Sea. The Ibiza rail was a relative of the extant water rail and may be derived from it, but was a bit smaller and stouter, had shorter and more robust hind limbs and shorter wings, with probably reduced its flight capability. Consequently, it might have also occurred on neighbouring Formentera, where no possible locations have been surveyed.
Porzana is a genus of birds in the crake and rail family, Rallidae. Its scientific name is derived from Venetian terms for small rails. The spotted crake is the type species.
Tetrao is a genus of birds in the grouse subfamily known as capercaillies. They are some of the largest living grouse. Feathers from the bird were used to create the characteristic hat of the bersaglieri, an Italian ace infantry formation.
The African rail is a small wetland bird of the rail family that is found in eastern and southern Africa.
Laterallus is a genus of birds in the rail family Rallidae. These small, relatively short-billed terrestrial rails are found among dense vegetation near water in the Neotropics, although a single species, the black rail, also occurs in the United States.
Pardirallus is a genus of bird in the family Rallidae. It contains three species native to marshland areas of Southern, Central America and the Caribbean, although fossil evidence indicates they once ranged north to what is now Idaho. They are 25–38 cm long and have a long greenish bill and reddish legs. The spotted rail is blackish-brown with white markings while the other two are brown above and dark grey below.
The Bogotá rail is a Vulnerable species of bird in subfamily Rallinae of family Rallidae, the rails, gallinules, and coots. It is endemic to Colombia. The bird is a typical medium-sized rail with a plump body that is laterally compressed, a short tail and an elongated bill.
The brown-cheeked rail or eastern water rail is a species of bird in the family Rallidae. It breeds in northern Mongolia, eastern Siberia, northeast China, Korea and northern Japan, and winters in southeast Asia. It used to be considered a subspecies of the water rail.
The mangrove rail is a species of bird in subfamily Rallinae of family Rallidae, the rails, gallinules, and coots. It is found in Central and South America.
