The rails, or Rallidae, are a large cosmopolitan family of small- to medium-sized, ground-living birds. The family exhibits considerable diversity and includes the crakes, coots, and gallinules. Many species are associated with wetlands, although the family is found in every terrestrial habitat except dry deserts, polar regions, and alpine areas above the snow line. Members of the Rallidae occur on every continent except Antarctica. Numerous island species are known. The most common rail habitats are marshland and dense forest. They are especially fond of dense vegetation.
The Eurasian coot, also known as the common coot, or Australian coot, is a member of the rail and crake bird family, the Rallidae. It is found in Europe, Asia, Australia, New Zealand and parts of North Africa. It has a slaty-black body, a glossy black head and a white bill with a white frontal shield. The sexes are similar. Similar looking coot species are found throughout the world, with the largest variety of coot species living in South America.
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. They are close relatives of the moorhen. However, the Coot typically appears 'dumpier' and lacks the distinctive red frontal face of the moorhen.
The New Zealand swan is an extinct indigenous swan from the Chatham Islands and the South Island of New Zealand. Discovered as archaeological remains in 1889, it was originally considered a separate species from the Australian black swan because of its slightly larger bones, and swans not having been introduced to New Zealand until 1864. From 1998 until 2017, it was considered to be simply a New Zealand population of Cygnus atratus, until DNA recovered from fossil bones determined that it was indeed a separate species, much larger and heavier than its Australian relative.
Moorhens—sometimes called marsh hens—are medium-sized water birds that are members of the rail family (Rallidae). Most species are placed in the genus Gallinula, Latin for "little hen". They are close relatives of coots. They are often referred to as (black) gallinules. Recently, one of the species of Gallinula was found to have enough differences to form a new genus Paragallinula with the only species being the lesser moorhen.
The white swamphen, also known as the Lord Howe swamphen, Lord Howe gallinule or white gallinule, is an extinct species of rail which lived on Lord Howe Island, east of Australia. It was first encountered when the crews of British ships visited the island between 1788 and 1790, and all contemporary accounts and illustrations were produced during this time. Today, two skins exist: the holotype in the Natural History Museum of Vienna, and another in Liverpool's World Museum. Although historical confusion has existed about the provenance of the specimens and the classification and anatomy of the bird, it is now thought to have been a distinct species endemic to Lord Howe Island and most similar to the Australasian swamphen. Subfossil bones have also been discovered since.
The red-knobbed coot or crested coot,, is a member of the rail and crake bird family, the Rallidae.
The Mascarene coot is an extinct species of coot that inhabited the Mascarene islands of Mauritius and Réunion. Long known from subfossil bones found in the Mare aux Songes swamp on the former island, but only assumed from descriptions to also have been present on the latter, remains have more recently been found on Réunion also. Early travellers' reports from Mauritius were, in reverse, generally assumed to refer to common moorhens, but it seems that this species only colonized the island after the extinction of the endemic coot.
Hawkins's rail, also called the giant Chatham Island rail or mehonui, is an extinct species of flightless rail. It was endemic to the Chatham Islands east of New Zealand. It is known to have existed only on the main islands of Chatham Island and Pitt Island. Hawkins's rail was the largest terrestrial bird native to the Chatham Islands, around 40 centimetres (16 in) tall and weighing about 2 kilograms (4.4 lb). It had a long, downward curving beak. Historic accounts likely referring to the bird by the name "mehonui" suggest that it was red-brown in colour, and it has been compared to the weka in ecological habits, using its beak to probe decaying wood for invertebrates. Hawkins's rail likely became extinct due to overhunting by the islands native inhabitants, the Moriori, and the bird is known from skeletal remains found in their kitchen middens.
The Chatham parakeet, also known as Forbes' parakeet, is a rare parakeet endemic to the Chatham Islands group, New Zealand. This parakeet is one of New Zealand's rarest birds and is classified as Vulnerable on the IUCN Red List, as a result of a range of threats to the species survival, including habitat loss, predation, and hybridization. A number of conservation methods have been employed to assist the recovery of this species, and currently the population trend is considered stable.
The red-gartered coot is a species of bird in subfamily Rallinae of family Rallidae, the rails, gallinules, and coots. It is found in Argentina, Brazil, Chile, Paraguay, and Uruguay.
The giant coot is a species of bird in subfamily Rallinae of family Rallidae, the rails, gallinules, and coots. It is found in Argentina, Bolivia, Chile, and Peru.
The red-fronted coot is a species of bird in subfamily Rallinae of family Rallidae, the rails, gallinules, and coots. It is found in Argentina, Bolivia, Brazil, Chile, Peru, and Uruguay.
The Chatham shag, also known as the Chatham Island shag, is a species of bird in the cormorant and shag family, Phalacrocoracidae. It is endemic to the Chatham Islands of New Zealand. For a long time the species was placed in the genus Phalacrocorax; today it is mostly placed with the other blue-eyed shags of New Zealand and Antarctica in the genus Leucocarbo. Its closest relative is the Otago shag of South Island.
Hodgens' waterhen is an extinct rail species from New Zealand. Its name commemorates the Hodgen brothers who were owners of the Pyramid Valley swamp where the holotype was discovered. It reached a weight of 280 g and its wings were so reduced that it was unable to fly. It occupied a wide range of habitats, including open forest and grassland along riverbanks.
The Chatham kākā or Chatham Island kākā is an extinct parrot species previously found on the Chatham Islands, New Zealand. The first individuals were thought to belong to the New Zealand kākā, but detailed examination of the subfossil bones showed that they actually belong to a separate endemic species. The species became extinct within the first 150 years of the arrival of the Polynesians around 1500, long before any European settlers. No skins or descriptions are available.
The Barbados rail is a fossil rail species endemic to Barbados with an undetermined taxonomic status. It was formerly described by Pierce Brodkorb in 1965 as Fulica podagrica. However, this classification has been questioned by Storrs Olson when he described Brodkorb's material anew in 1974. It is only known by Brodkorb's holotype which consists of a humerus and several leg elements including femur, tibiotarsus and tarsometatarsus fragments. The humerus may not be specifically distinct from those of the American coot but most of the femur, tibiotarsus and tarsometarsus fragments are from a yet undescribed larger rail of an undetermined genus not related to Fulica. Olson further assumed that Brodkorb's material might be a composite of several rail species. The bone fragments were unearthed in Late Pleistocene deposits in Saint Philip Parish and Ragged Point on Barbados.
The New Zealand coot is an extinct bird in the rail family, Rallidae, that was endemic to New Zealand. It was described in 1893 by New Zealand naturalist, ethnologist and museum director Augustus Hamilton, from material he had collected the previous year at Castle Rocks on the Ōreti River in Southland. The Latin specific epithet prisca means "old", referring to its subfossil occurrence. Remains have subsequently been found at several sites in both North and South Islands.
