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.
Members of the parrot genus Psittacula or Afro-Asian ring-necked parrots, as they are commonly known in aviculture, originate from Africa to South-East Asia. It is a widespread group with a clear concentration of species in south Asia, but also with representatives in Africa and the islands of the Indian Ocean. This is the only genus of parrot which has the majority of its species in continental Asia. Of all the extant species only Psittacula calthropae, Psittacula caniceps and Psittacula echo do not have a representative subspecies in any part of mainland continental Asia. The rose-ringed parakeet, Psittacula krameri, is one of the most widely distributed of all parrots.
The Rodrigues rail, also known as Leguat's gelinote or Leguat's rail, is an extinct species of the rail family that was endemic to the Mascarene island of Rodrigues, east of Madagascar in the Indian Ocean. It is generally kept in its own genus, Erythromachus, but has sometimes been assigned to the genus Aphanapteryx along with its close relative the red rail of Mauritius; their relationship with other rails is unclear. The Rodrigues rail was about 35 cm (14 in) long and weighed at least 500 g (18 oz). It was described as having grey plumage, a red beak, red legs, and a naked red patch around the eye. The beak was long and curved downwards. It was flightless and fed on tortoise eggs. It was described as being attracted to red objects, which humans exploited while hunting it.
The Mascarene parrot or mascarin is an extinct species of parrot that was endemic to the Mascarene island of Réunion in the western Indian Ocean. The taxonomic relationships of this species have been subject to debate; it has historically been grouped with either the Psittaculini parrots or the vasa parrots, with the latest genetic study favouring the former group.
The white-crowned manakin is a small passerine bird in the manakin family Pipridae. This common and extremely widespread manakin is one of the most easily identified, even in female plumage. It is a resident breeder in the tropical New World from Costa Rica to northeastern Peru and eastern Brazil. It was traditionally placed in the genus Pipra, but is now placed in its own monotypic genus Pseudopipra. It is a small, compact bird about 10 cm (3.9 in) long. Males have black plumage with a white crown which can be erected as a crest, the only member of the Pipridae to possess both an all-black body and a gleaming white crown. Females and juveniles are olive-green, with a grey head and throat, and greyish-green or olive underparts. At breeding time, males are involved in a lekking behaviour. This is a fairly common species with a wide range, and the International Union for Conservation of Nature has rated its conservation status as being of "least concern".
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.
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.
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 white-throated rail or Cuvier's rail, is a species of bird in the family Rallidae.
The lesser moorhen is a species of bird in the family Rallidae. It is sometimes placed into the genus Gallinula. It is the only member of the genus Paragallinula.
The yellow-bellied flyrobin is a species of passerine bird in the Australasian robin family Petroicidae. It is the only species in the genus Cryptomicroeca. The yellow-bellied flyrobin is endemic to New Caledonia, where it occurs on the island of Grande Terre. It occupies a range of habitats, including dry lowlands, woodland, Pinus and Pandanus forest, and humid forest from sea level up to 1,525 m (5,000 ft).
The many-colored rush tyrant or many-coloured rush tyrant is a small passerine bird of South America belonging to the tyrant flycatcher family, Tyrannidae. It is the only member of the genus Tachuris and is sometimes placed in a separate monotypic family. It inhabits marshland and reedbeds around lakes and rivers. It is particularly associated with stands of Scirpus. The nest is built among plant stems.
The star-throated antwren is an insectivorous bird in the antbird family Thamnophilidae. It is endemic to the Atlantic Forest region of southeast Brazil. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest.
The forest robin or orange-breasted forest robin is a species of bird from Central and West Africa. It is monotypic in the genus Stiphrornis. It has been placed in the family Turdidae, but is now generally placed in Muscicapidae in the group popularly known as chats. Most taxonomists consider it a single species, but some reviews have recommended recognizing 5 species. It has a total length of around 12 cm, has dark upperparts, and a throat and chest that, depending on the subspecies, is yellow-orange or deep orange.
Sarothruridae is a family of small- to medium-sized ground-living birds found mostly in Madagascar and sub-Saharan Africa, with the genus Rallicula being restricted to New Guinea and the Moluccas. The species in this family were once considered to sit with the larger rail family Rallidae.
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.
Eurypygiformes is an order formed by the kagus, comprising two species in the family Rhynochetidae endemic to New Caledonia, and the sunbittern from the tropical regions of the Americas. Its closest relatives appear to be the tropicbirds of the tropical Atlantic, Indian, and Pacific oceans.
