The gray peacock-pheasant (Polyplectron bicalcaratum), also known as Burmese peacock-pheasant, is a large Asian member of the order Galliformes.
In 1747 the English naturalist George Edwards included an illustration and a description of the grey peacock-pheasant in the second volume of his A Natural History of Uncommon Birds. He used the English name "The Peacock Pheasant from China". Edwards based his hand-coloured etching on a live bird which was given to Robert Walpole, 1st Earl of Orford. [4] When in 1758 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the tenth edition, he placed the grey peacock-pheasant with the Indian peafowl in the genus Pavo . Linnaeus included a brief description, coined the binomial name Pavo bicalcaratum and cited Edwards' work. [5] The grey peacock-pheasant is now placed in the genus Polyplectron that was introduced in 1807 by the Dutch zoologist Coenraad Jacob Temminck. [6] [7] The genus name Polyplectron combines the Ancient Greek polus meaning "many" with plēktron meaning "cock's spur". The specific epithet bicalcaratum combines the Latin bi meaning "two" with calcar, calcaris meaning "spur". [8]
Although several subspecies have been described, none are currently recognised in the list of world birds maintained by Frank Gill, Pamela Rasmussen and David Donsker on behalf of the International Ornithological Committee (IOC). [7]
Other subspecies have been described in the past, but these are not now recognised: [7] [9]
One previous subspecies, the Hainan peacock-pheasant (P. b. katsumatae), is now recognised as a separate species by the IOC. [7]
Lowe's grey peacock-pheasant was described from a captive bird of unknown provenance. [10] Similar examples have turned up on occasion, but the validity and – if distinct – home range of this taxon remains unknown. It was theorized to inhabit western Assam or the eastern Himalayas, but this is based on conjecture.
The phylogeny of this species is fairly enigmatic. mtDNA cytochrome b and D-loop as well as the nuclear ovomucoid intron G sequence data confirms that it belongs to a largely Continental Asian clade together with Germain's peacock-pheasant (P. germaini), but also the "brown" southern species bronze-tailed peacock-pheasant (P. chalcurum) and mountain peacock-pheasant (P. inopinatum). [11]
The ovomucin sequence seems to have evolved convergently or with a decreased mutational rate on the grey and the bronze-tailed peacock-pheasant. Though they are quite similar on the molecular level, the distance and interspersed populations of their closest relatives argue against a much more recently shared common ancestry between them versus the other two "northern" peacock-pheasants. Also, the cytochrome b and D-loop data does not support a closer relationship between P. bicalcaratus and P. chalcurum; overall, as it seems the four species' ancestors separated during a very short timespan. [11]
Note however that in the absence of dedicated phylogeographic studies, the molecular data is only of limited value in this species, the most morphologically diverse and widespread peacock-pheasant: There is no data on the origin and number of specimens, but it is unlikely that more than one or two individuals – possibly of captive origin and undeterminable subspecific allocation – were sampled. All that can be reasonably assumed is that the grey peacock-pheasant evolved on mainland Southeast Asia, probably during the Late Pliocene to Early Pleistocene 3.6-1 million years ago. [12]
It is a large pheasant, up to 76 cm long and greyish brown with finely spotted green eyespots, an elongated bushy crest, bare pink or yellow facial skin, white throat, and grey iris, bill and legs. The sexes are rather similar, but the female is smaller, darker and less ornamented than the male. The young resemble the female.
The grey peacock-pheasant is distributed in lowland and hill forests of Bangladesh, Northeast India and Southeast Asia, but excluding most of Indochina as well as the entire Malayan Peninsula. The diet consists mainly of seeds, termites, fruits and invertebrates. The female usually lays two eggs.
Widespread throughout its large range, the grey peacock-pheasant is evaluated as a Species of Least Concern on the IUCN Red List of Threatened Species. It is listed on CITES Appendix II, restricting trade in wild-caught birds to preserve its stocks. [13]
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 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 than to other pheasants.
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 Phasianidae are a family of heavy, ground-living birds, which includes pheasants, partridges, junglefowl, chickens, turkeys, Old World quail, and peafowl. The family includes many of the most popular gamebirds. The family is a large one and includes 184 species divided into 54 genera. It was formerly broken up into two subfamilies, the Phasianinae and the Perdicinae. However, this treatment is now known to be paraphyletic and polyphyletic, respectively, and more recent evidence supports breaking it up into three subfamilies: Rollulinae, Phasianinae, and Pavoninae. The New World quail (Odontophoridae) and guineafowl (Numididae) were formerly sometimes included in this family, but are now typically placed in families of their own; conversely, grouse and turkeys, formerly often treated as distinct families, are now known to be deeply nested within Phasianidae, so they are now included in the present family.
Junglefowl are the only five living species of bird from the genus Gallus in the bird order Galliformes, and occur in parts of South and Southeast Asia. They diverged from their common ancestor about 4–6 million years ago.
The double-spurred spurfowl is a gamebird in the pheasant family Phasianidae of the order Galliformes, gallinaceous birds. Like most spurfowls, it is restricted to Africa. It is a resident breeder in tropical west Africa, but there is a small and declining isolated population in Morocco.
The black-billed amazon is a parrot endemic to Jamaica. Sometimes called the black-billed parrot, this amazon parrot is mostly green with small patches of red on the wing and sometimes flecked on the head. Its bill makes it easy to separate from most other amazons, including the yellow-billed amazon, which also lives in Jamaica. It is the smallest Amazona parrot at 25 cm (10 in).
The satyr tragopan also known as the crimson horned pheasant, is a pheasant found in the Himalayan reaches of India, Tibet, Nepal and Bhutan. They reside in moist oak and rhododendron forests with dense undergrowth and bamboo clumps. They range from 2400 to 4200 meters in summer and 1800 meters in winter. The male is about 70 cm long.
The Palawan peacock-pheasant is a medium-sized bird in the family Phasianidae.
Pavo is a genus of two species in the pheasant family. The two species, along with the Congo peacock, are known as peafowl.
The peacock-pheasants are a bird genus, Polyplectron, of the family Phasianidae, consisting of eight species. They are colored inconspicuously, relying on heavily on crypsis to avoid detection. When threatened, peacock-pheasants will alter their shapes using specialised plumage that when expanded reveals numerous iridescent orbs. The birds also vibrate their plume quills further accentuating their aposematism. Peacock-pheasants exhibit well developed metatarsal spurs. Older individuals may have multiple spurs on each leg. These kicking thorns are used in self-defense.
The Bornean peacock-pheasant is a medium-sized pheasant. It is probably the rarest and certainly the least known of all peacock-pheasants. This elusive bird is endemic to lowland forests of Borneo.
The Malayan peacock-pheasant also known as crested peacock-pheasant or Malaysian peacock-pheasant, is a medium-sized pheasant of the galliform family Phasianidae. The closely related Bornean peacock-pheasant was formerly included here as a subspecies, but as understood today, P. malacense is monotypic.
The bronze-tailed peacock-pheasant is also known as the Sumatran peacock-pheasant. It is an Indonesian bird.
The mountain peacock-pheasant also known as Rothschild's peacock-pheasant or mirror pheasant is a medium-sized, up to 65 cm long, blackish brown pheasant with small ocelli and long graduated tail feathers. Both sexes are similar. The male has metallic blue ocelli on upperparts, green ocelli on tail of twenty feathers and two spurs on legs. Female has black ocelli on upperparts, unspurred legs and tail of eighteen feathers. The female is smaller and duller than male.
The ruddy quail-dove is a species of bird in the dove and pigeon family Columbidae. It breeds throughout the West Indies, Central America, and tropical South America. It has appeared as a vagrant in Florida and southern Texas. It lays two buff-colored eggs on a flimsy platform built on a shrub. Some nests are built on the ground.
Germain's peacock-pheasant is a pheasant that is endemic to Indochina. The name commemorates the French colonial army's veterinary surgeon Louis Rodolphe Germain.
The ornate lorikeet, sometimes named the ornate lory, is a species of parrot in the family Psittaculidae. It is endemic to the Sulawesi archipelago in Indonesia. It is found in forest, woodland, mangrove and plantations, and is locally common.
The southern red bishop or red bishop is a small passerine bird belonging to the bishop and widowbird genus Euplectes in the weaver family, the Ploceidae. It is common in wetlands and grassland in Africa south of the Equator. North of the Equator, it is replaced by the northern red bishop or orange bishop which was formerly regarded as a subspecies of this species.
The Hainan peacock-pheasant is an endangered bird that belongs to the pheasant family Phasianidae. It is endemic to the island of Hainan, China. It is extremely rare.
