Amaurornis Phoenicurus - Singapore Botanic Gardens
''Amaurornis'' is a genus of birds in the rail family Rallidae. The species in this genus are typically called bush-hens. A monotypic subtribe, Amaurornithina, was proposed for this genus. Taxonomy The genus ''Amaurornis'' was erected by the German naturalist Ludwig Reichenbach in 1853 with the plain bush-hen (''Amaurornis olivacea'') as the type species. The name comes from the Greek ''amauros'', meaning "dusky" or "brown" and ''ornis'', meaning "bird". The New Guinea flightless rail was sometimes included in this genus, but more often held to constitute a distinct monotypic genus ''Megacrex''. The first cladistic studies of rails, based on morphology, strongly suggested that ''Amaurornis'' as traditionally defined is not monophyletic, and that several species placed here are in fact closer to the small crakes traditionally placed in ''Porzana ''Porzana'' is a genus of birds in the crake and rail family, Rallidae.

White-breasted Waterhen
The white-breasted waterhen (''Amaurornis phoenicurus'') is a waterbird of the rail and crake family, Rallidae, that is widely distributed across South and Southeast Asia. They are dark slaty birds with a clean white face, breast and belly. They are somewhat bolder than most other rails and are often seen stepping slowly with their tail cocked upright in open marshes or even drains near busy roads. They are largely crepuscular in activity and during the breeding season, just after the first rains, make loud and repetitive croaking calls. Description Adult white-breasted waterhens have mainly dark grey upperparts and flanks, and a white face, neck and breast. The lower belly and undertail are cinnamon or white coloured. The body is flattened laterally to allow easier passage through the reeds or undergrowth. They have long toes, a short tail and a yellow bill and legs. Sexes are similar but females measure slightly smaller. Immature birds are much duller versions of the adults. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monophyletic
In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants. Monophyletic groups are typically characterised by shared derived characteristics ( synapomorphies), which distinguish organisms in the clade from other organisms. An equivalent term is holophyly. The word "mono-phyly" means "one-tribe" in Greek. Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic group'' consists of all of the descendants of a common ancestor minus one or more monophyletic groups. A '' polyphyletic group'' is characterized by convergent features or habits of scientific interest (for example, night-active primates, fruit trees, aquatic insects). The features by which a polyphyletic group is differentiated from others are not inherited from a common ancestor. These definitions have tak ...

Bird Genera
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. Bi ...

Pale-vented Bush-hen
The pale-vented bush-hen (''Amaurornis moluccana'') is a medium sized waterbird, mainly blue-grey with a buff vent and undertail. It is found in Australia, the Moluccan Islands, New Guinea, the Bismarck Archipelago and the Solomon Islands. Its natural habitat is subtropical or tropical moist lowland forests. Description The pale-vented bush-hen is medium sized with a body length between , wing length of , bill length of and weighing between . It has a dull gray-blue body, brown wings and tail. Its eponymous pale coloured vent and undertail are variously described as buff-ruffous, rufous-brown, buff or reddish-brown. The bill is distinctive being lime green with an orange red frontal shield when breeding and duller green with no red when not breeding. The legs are olive-yellow and the eye dark. There is no apparent difference between sexes. Juveniles are paler in colour. Taxonomy and systematics The pale-vented bush-hen is a member of the ''Rallidae'' family which include ...

Isabelline Bush-hen
The isabelline bush-hen (''Amaurornis isabellina''), also known as Sulawesi waterhen or isabelline waterhen, is a large, up to 40 cm long, rufous and brown rail. The term '' isabelline'' refers to the colouration. It is the largest member of the genus ''Amaurornis''. Both sexes are similar with olive brown plumage, pale green bill, greenish brown legs and rufous below. An Indonesian endemic, the isabelline waterhen is confined to grasslands near waters and lowlands of Sulawesi. The call is a loud "tak-tak-tak-tak". Widespread throughout its natural habitat, the isabelline waterhen is evaluated as least concern on the IUCN Red List The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biol ... of Threatened Species.

Talaud Bush-hen
The Talaud bush-hen (''Amaurornis magnirostris'') is a vulnerable waterbird in the rail and crake family. It is a recently described species from Karakelang Island in the Talaud Islands, Indonesia. It occurs in forest, scrub, and overgrown plantations. Description Talaud bush-hen is a 30.5 cm long, large, very dark and robust bush-hen. Its large head and its upperparts are dark brown, and its underparts and flanks are very dark bluish grey. The large, thick bill is pale green, and the legs are yellow, becoming more olive at the rear. The only confirmed call of this shy species is a series of loud, low-pitched croaking barks, but it is likely that it also makes the shrieks typical of bush-hens. Status The population is estimated at 2,350-9,560 individuals on Karakelang. It may also occur on neighbouring islands, but there is little forest on those, less than 20 km2 compared to 350 km2 on Karakelang. There are two protected areas totalling 21,800 hectares, bu ...

Porzana
''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 (''P. porzana'') is the type species. Taxonomy The genus ''Porzana'' was erected by the French ornithologist Louis-Pierre Vieillot in 1816 with the spotted crake (''Porzana porzana'') as the type species. The genus unites the typical "crakes" found essentially anywhere in the world except desert and polar regions. It contains 3 living species. In addition, a large number of prehistorically extinct species known only from fossil or subfossil remains have been discovered. The genera ''Coturnicops'', '' Crex'' (including ''Crecopsis'') and ''Laterallus'' have been suggested to be closely related. However, molecular phylogenetic analyses have confirmed the suspicion, raised in the late 20th century in the first cladistic studies of morphology, that the "genus" ''Porzana'' is rather an evolutionary grade, consisting of an asse ...
