Rheinardia
Crested arguses are large and spectacular peafowl-like birds in the genus ''Rheinardia'' of the pheasant family. Taxonomy Although traditionally treated as a single species with two subspecies, it has long been suspected that a species pair is involved and recent evidence, albeit using the controversial Tobias criteria, also supports treating each subspecies as a separate species. The split results in two monotypic species: The two forms differ significantly in plumage, display and vocalisations and both are threatened by human activity. Description Crested arguses have dark-brown-spotted black and buff plumage, a heavy pink bill, brown irises and blue skin around the eyes. The head has two crests; the hind crest, which extends down the occiput, is erected when alarmed and during intentional behaviors including pair bonding and courtship displays. The male has a broad and greatly elongated tail of twelve feathers. The tail covert (or "train") of the male is the longest of ...

Vietnamese Crested Argus
The Vietnamese crested argus (''Rheinardia ocellata'') is a large and spectacular peafowl-like species of bird in the pheasant family with dark-brown-spotted black and buff plumage, a heavy pink bill, brown irises and blue skin around the eyes. The head has two crests; the hind crest, which extends down the occiput, is erected when alarmed and during intentional behaviors including pair bonding and courtship displays. The male has a broad and greatly elongated tail of twelve feathers. The tail covert (or "train") of the male is the longest of any bird and is believed to contain the longest (and widest) feathers to occur in a wild bird; the Reeves's pheasant has tail feathers of similar length but which are considerably narrower. The tail coverts measure up to in length, giving the bird a total length of .

Great Argus
The great argus (''Argusianus argus'') is a species of pheasant from Southeast Asia. It is not to be confused with the two species of closely related crested argus, genus ''Rheinardia''. Taxonomy Carl Linnaeus gave the great argus its specific name (from which its common name and genus name are derived) because of the intricate eye-like patterns on its wings, in reference to Argus, a hundred-eyed giant in Greek mythology. There are two subspecies recognized: Nominate ''argus'' of the Malay peninsula and Sumatra, and ''A. a. grayi'' of Borneo. William Beebe considered the two races to be distinct species, but they have since been lumped. Double-banded argus The double-banded argus (''Argusianus bipunctatus''), known only from a portion of a single primary flight feather, was long considered a potential second species. It was described in 1871 from this feather piece, found in a millinery shipment imported to London. Its origin was hypothesized to be from Java, Indonesi ...

Galliformes
Galliformes is an order of heavy-bodied ground-feeding birds that includes turkeys, chickens, quail, and other landfowl. Gallinaceous birds, as they are called, are important in their ecosystems as seed dispersers and predators, and are often reared by humans for their meat and eggs, or hunted as game birds. The order contains about 290 species, inhabiting every continent except Antarctica, and divided into five families: Phasianidae (including chicken, quail, partridges, pheasants, turkeys, peafowl (peacocks) and grouse), Odontophoridae (New World quail), Numididae (guinea fowl), Cracidae (including chachalacas and curassows), and Megapodiidae (incubator birds like malleefowl and brush-turkeys). They adapt to most environments except for innermost deserts and perpetual ice. Many gallinaceous species are skilled runners and escape predators by running rather than flying. Males of most species are more colorful than the females, with often elaborate courtship ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pheasant
Pheasants ( ) are birds of several genera within the family Phasianidae in the order Galliformes. Although they can be found all over the world in introduced (and captive) populations, the pheasant genera native range is restricted to Eurasia. The classification "pheasant" is paraphyletic, as birds referred to as pheasants are included within both the subfamilies Phasianinae and Pavoninae, and in many cases are more closely related to smaller phasianids, grouse, and turkey (formerly classified in Perdicinae, Tetraoninae, and Meleagridinae) than to other pheasants. Pheasants are characterised by strong sexual dimorphism, males being highly decorated with bright colours and adornments such as wattles. Males are usually larger than females and have longer tails. Males play no part in rearing the young. A pheasant's call or cry can be recognised due to the fact it sounds like a rusty sink or valve being turned. Pheasants eat mostly seeds, grains, roots, and berries, while ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peafowl
Peafowl is a common name for three bird species in the genera '' Pavo'' and '' Afropavo'' within the tribe Pavonini of the family Phasianidae, the pheasants and their allies. Male peafowl are referred to as peacocks, and female peafowl are referred to as peahens, although peafowl of either sex are often referred to colloquially as "peacocks." The two Asiatic species are the blue or Indian peafowl originally of the Indian subcontinent, and the green peafowl of Southeast Asia; the one African species is the Congo peafowl, native only to the Congo Basin. Male peafowl are known for their piercing calls and their extravagant plumage. The latter is especially prominent in the Asiatic species, which have an eye-spotted "tail" or "train" of covert feathers, which they display as part of a courtship ritual. The functions of the elaborate iridescent colouration and large "train" of peacocks have been the subject of extensive scientific debate. Charles Darwin suggested that they ser ...

Laos
Laos (, ''Lāo'' )), officially the Lao People's Democratic Republic ( Lao: ສາທາລະນະລັດ ປະຊາທິປະໄຕ ປະຊາຊົນລາວ, French: République démocratique populaire lao), is a socialist state and the only landlocked country in Southeast Asia. At the heart of the Indochinese Peninsula, Laos is bordered by Myanmar and China to the northwest, Vietnam to the east, Cambodia to the southeast, and Thailand to the west and southwest. Its capital and largest city is Vientiane. Present-day Laos traces its historic and cultural identity to Lan Xang, which existed from the 14th century to the 18th century as one of the largest kingdoms in Southeast Asia. Because of its central geographical location in Southeast Asia, the kingdom became a hub for overland trade and became wealthy economically and culturally. After a period of internal conflict, Lan Xang broke into three separate kingdoms: Luang Phrabang, Vientiane and Champasak. In ...

Polygamous
Crimes Polygamy (from Late Greek (') "state of marriage to many spouses") is the practice of marrying multiple spouses. When a man is married to more than one wife at the same time, sociologists call this polygyny. When a woman is married to more than one husband at a time, it is called polyandry. In contrast to polygamy, monogamy is marriage consisting of only two parties. Like "monogamy", the term "polygamy" is often used in a ''de facto'' sense, applied regardless of whether a state recognizes the relationship.For the extent to which states can and do recognize potentially and actual polygamous forms as valid, see Conflict of marriage laws. In sociobiology and zoology, researchers use ''polygamy'' in a broad sense to mean any form of multiple mating. Worldwide, different societies variously encourage, accept or outlaw polygamy. In societies which allow or tolerate polygamy, in the vast majority of cases the form accepted is polygyny. According to the ''Ethnograph ...
