The Gruiformes are an order containing a considerable number of living and extinct bird families, with a widespread geographical diversity. Gruiform means "crane-like".
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.
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.
Flufftails are small birds related to rails and finfoots. There are nine species, seven of which are distributed across sub-Saharan Africa, with the remaining two in Madagascar. The genus was long placed with the rail family Rallidae, but is now placed in the family Sarothruridae, along with three other species of wood rails.
The Madagascar forest rail, also known as the Madagascar wood rail or the kioloides rail, is a species of bird in the family Sarothruridae. It is endemic to forests, often in wet areas, in northern and eastern Madagascar. The Madagascar forest rail is a secretive and shy species, often showing elusive behavior, such as running away from the slightest disturbances. This has contributed to a lack of study on this species; a reason why it is not that well known.
The grey-throated rail is a species of bird in the family Rallidae, the only member of the genus Canirallus. It is found in Cameroon, Central African Republic, Republic of the Congo, Democratic Republic of the Congo, Ivory Coast, Equatorial Guinea, Gabon, Ghana, Guinea, Liberia, Nigeria, and Sierra Leone.
The spotted rail is a species of bird in the subfamily Rallinae of the rail, crake, and coot family Rallidae. It is found in Mexico, Central America, the Caribbean, and South America.
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.
Rallina is a genus of bird in the rail family, Rallidae. It contains four species found in forest and marshland in Asia and Australasia. They are 18–34 cm long and mainly chestnut or brown, often with black and white markings.
The striped flufftail is a species of bird in the flufftail family Sarothruridae. It is also known as the red-tailed flufftail. The species is closely related to the Madagascar flufftail. The species has a disjunct distribution across the Afromontane of southeastern Africa, with two subspecies. The nominate subspecies S. a. affinis is found in eastern South Africa and Eswatini. S. a. antonii, named for German ornithologist Anton Reichenow, is found in eastern Zimbabwe and Mozambique, Malawi, southern Tanzania, Kenya and the south of South Sudan.
The white-winged flufftail is a very rare African bird in the family Sarothruridae. The estimated global population size of white-winged flufftails is less than 250 adults. These birds reside in Ethiopia and South Africa but it is unknown whether these populations are one large or two different populations.
The Madagascar flufftail is a species of bird in the family Sarothruridae. It is endemic to Madagascar. The subspecies is Monotypic.
Rallicula is a genus of bird in the family Sarothruridae. It contains four species endemic to the island of New Guinea.
Mentocrex is a genus of birds in the flufftail family, Sarothruridae. The genus includes two species, both of which are endemic to forests in Madagascar.
The Tsingy forest rail, also known as the Tsingy forest rail, is a species of bird in the family Sarothruridae that was scientifically described in 2011.
Zapornia is a genus of birds in the rail family Rallidae. It was included in Porzana for much of the late 20th century. These smallish to tiny rails are found across most of the world, but are entirely absent from the Americas except as wind-blown stray birds. A number of species, and probably an even larger number of prehistorically extinct ones, are known only from small Pacific islands; a number of these had lost the ability to fly in the absence of terrestrial predators.
