Alectoris
''Alectoris'' is a genus of partridges in the family Phasianidae, closely related to Old World quail (''Coturnix'' and relatives), snowcocks (''Tetraogallus''), partridge-francolins (''Pternistis''), bush quail (''Perdicula''), and sand and see-see partridges (''Ammoperdix''). Members of the genus are known collectively as rock partridges (a name that also refers to one species in particular, ''Alectoris graeca''). The genus name is derived from the , meaning "chicken" or "farmyard fowl". Their fossils date back to the early Pleistocene, with extant representatives in southern Europe, North Africa and Arabia, and across Asia in Pakistan to Tibet and western China. Taxonomy The genus ''Alectoris'' was introduced in 1829 by German naturalist Johann Jakob Kaup to accommodate a single species ''Perdrix petrosa'', a junior synonym of ''Perdix barbara'' Pierre Joseph Bonnaterre, Bonnaterre, 1790, the Barbary partridge, which is therefore the type species by monotypy.

Chukar Partridge
The chukar partridge (''Alectoris chukar''), or simply chukar, is a Palearctic upland Upland game, gamebird in the pheasant family Phasianidae. It has been considered to form a superspecies complex along with the rock partridge, Philby's partridge and Przevalski's partridge and treated in the past as conspecific particularly with the first. This partridge has well-marked black and white bars on the flanks and a black band running from the forehead across the eye down the head to form a necklace that encloses a white throat. Native to Asia, the species has been introduced into many other places and feral populations have established themselves in parts of North America, Malta and New Zealand. This bird can be found in parts of Middle East and temperate Asia. Description The chukar is a rotund long partridge, with a light brown back, grey breast, and buff belly. The shades vary across the various populations. The face is white with a black gorget (birds), gorget. It has Wikt:ru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barbary Partridge
The Barbary partridge (''Alectoris barbara'') is a gamebird in the pheasant family (Phasianidae) of the order Galliformes. It is native to North Africa. Distribution The Barbary partridge has its main native range in North Africa, and is also native to Gibraltar and the Canary Islands (''Alectoris barbara'' ssp. ''koenigi''). It has been introduced to continental Portugal and Madeira, though there are no recent records of this species on the latter islands. It is also present in Sardinia. Description The Barbary partridge is a rotund bird, with a grey-brown back, grey breast and buff belly. The face is light grey with a broad reddish-brown gorget. It has rufous-streaked white flanks and red legs. When disturbed, it prefers to run rather than fly, but if necessary it flies a short distance on rounded wings. It is closely related to its western European equivalent, the red-legged partridge. It is similar to the red-legged partridge, but it has a different head and neck pattern. T ...

Alectoris Graeca
The rock partridge or common rock partridge (''Alectoris graeca'') is a gamebird in the pheasant family, Phasianidae, of the order Galliformes (gallinaceous birds). It is native to southern Europe, and is closely related and very similar to its eastern equivalent, the chukar partridge, ''A. chukar''. Habitat It is a resident breeder in dry, open and often hilly country. Breeding It nests in a scantily lined ground scrape laying 5–21 eggs. Diet The rock partridge takes a wide variety of seeds and some insect food. Description The rock partridge is a rotund bird, with a light brown back, grey breast and buff belly. The face is white with a black gorget. It has rufous-streaked flanks and red legs. When disturbed, it prefers to run rather than fly, but if necessary it flies a short distance on rounded wings. It is very similar to the chukar partridge, but is greyer on the back and has a white, not yellowish foreneck. The sharply defined gorget distinguishes this species from red ...

Partridge
A partridge is a medium-sized Galliformes, galliform bird in any of several genera, with a wide Indigenous (ecology), native distribution throughout parts of Europe, Asia and Africa. Several species have been introduced to the Americas. They are sometimes grouped in the Perdicinae subfamily of the Phasianidae (pheasants, quail, etc.). However, molecular research suggests that partridges are not a distinct taxon within the family Phasianidae, but that some species are closer to the pheasants, while others are closer to the junglefowl. Description Partridges are medium-sized Game (hunting), game birds, generally intermediate in size between the larger pheasants, smaller quail; they're ground-dwelling birds that feature variable plumage colouration across species, with most tending to grey and brown. Range and habitat Partridges are native to Europe, Asia, Africa, and the Middle East. Some species are found nesting on steppes or agricultural land, while other species prefer mor ...

Phasianidae
Phasianidae is a family (biology), family of heavy, ground-living birds, which includes pheasants, grouse, partridges, junglefowl, chickens, Turkey bird, turkeys, Old World quail, and peafowl. The family includes many of the most popular Game (hunting), gamebirds. The family includes 185 species divided into 54 genera. It was formerly broken up into two subfamily (biology), subfamilies, the Phasianinae and the Perdicinae. However, this treatment is now known to be paraphyly, paraphyletic and polyphyly, polyphyletic, respectively, and more recent evidence supports breaking it up into two subfamilies: Rollulinae and Phasianinae, with the latter containing multiple Tribe (biology), tribes within two clades. 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 turkey (bird), turkeys, formerly often treated as distinct families (Tetraonidae and Melea ...

Coturnix
''Coturnix'' is a genus of five extant species and five to eight known extinct species of Old World quail. Range These species are distributed throughout Africa, Eurasia, Australia, and formerly New Zealand. An extinct Adaptive radiation, radiation of Flightless bird, flightless, insular species is known through fossil remains from Macaronesia, which were likely wiped out by human arrival. Habits Quail of ''Coturnix'' live in pairs or small social groups and form larger groups during migration. Not all species migrate, but most are capable of extremely rapid, upward flight to escape from danger. Unlike related genera, Old World quail do not perch in trees. They devote much of their time to scratching and foraging for seeds and invertebrates on the ground. Typical habitats are dense vegetation such as grasslands, bushes alongside rivers and cereal fields. They are heavily predated upon by Accipitriformes, diurnal hawks. Taxonomy The genus ''Coturnix'' was introduced in 1764 by th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pternistis
''Pternistis'' is a genus of galliform birds formerly classified in the spurfowl group of the partridge subfamily of the pheasant family. They are described as "partridge-francolins" in literature establishing their phylogenetic placement outside the monophyletic assemblage of true spurfowls. All species are endemic to Sub-Saharan Africa, excepted the double-spurred spurfowl (also present in Morocco). They are commonly known as spurfowls or francolins, but are closely related to jungle bush quail, ''Alectoris'' rock partridges, and ''Coturnix'' quail. The species are strictly monogamous, remaining mated indefinitely. They procure most of their food by digging. Spurfowls subsist almost entirely on roots, beans of leguminous shrubs and trees, tubers, and seeds, and feasting opportunistically on termites, ants, locusts, flowers, and fruit. Important predators are jackals, caracals, servals, and birds of prey, as well as herons and marabou storks. Taxonomy The genus ''Pternist ...

Monotypy
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical system. ...

Ancient Greek
Ancient Greek (, ; ) includes the forms of the Greek language used in ancient Greece and the classical antiquity, ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Greek Dark Ages, Dark Ages (), the Archaic Greece, Archaic or Homeric Greek, Homeric period (), and the Classical Greece, Classical period (). Ancient Greek was the language of Homer and of fifth-century Athens, fifth-century Athenian historians, playwrights, and Ancient Greek philosophy, philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Homeric Greek, Epic and Classical periods of the language, which are the best-attested periods and considered most typical of Ancient Greek. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird Migration
Bird migration is a seasonal movement of birds between breeding and wintering grounds that occurs twice a year. It is typically from north to south or from south to north. Animal migration, Migration is inherently risky, due to predation and mortality. The Arctic tern holds the long-distance migration record for birds, travelling between Arctic breeding grounds and the Antarctic each year. Some species of Procellariiformes, tubenoses, such as albatrosses, circle the Earth, flying over the southern oceans, while others such as Manx shearwaters migrate between their northern breeding grounds and the southern ocean. Shorter migrations are common, while longer ones are not. The shorter migrations include altitudinal migrations on mountains, including the Andes and Himalayas. The timing of migration seems to be controlled primarily by changes in day length. Migrating birds navigate using celestial cues from the Sun and stars, the Earth's magnetic field, and mental maps.

Bird Nest
A bird nest is the spot in which a bird lays and Avian incubation, incubates its Bird egg, eggs and raises its young. Although the term popularly refers to a specific structures built by animals, structure made by the bird itself—such as the grassy cup nest of the American robin or Eurasian blackbird, or the elaborately woven hanging nest of the Montezuma oropendola or the village weaver—that is too restrictive a definition. For some species, a nest is simply a shallow depression made in sand; for others, it is the knot-hole left by a broken branch, a burrow dug into the ground, a chamber drilled into a tree, an enormous rotting pile of vegetation and earth, a shelf made of dried saliva or a mud dome with an entrance tunnel. The smallest bird nests are those of some hummingbirds, tiny cups which can be a mere across and high. At the other extreme, some nest mounds built by the dusky scrubfowl measure more than in diameter and stand nearly tall. The study of birds' nests ...

Pine Nuts
Pine nuts, also called piñón (), pinoli (), or pignoli, are the edible seeds of pines (family Pinaceae, genus ''Pinus''). According to the Food and Agriculture Organization, only 29 species provide edible nuts, while 20 are traded locally or internationally owing to their seed size being large enough to be worth harvesting; in other pines, the seeds are also edible but are too small to be of notable value as human food. The biggest producers of pine nuts are China, Russia, North Korea, Pakistan and Afghanistan. As pines are gymnosperms, not angiosperms (flowering plants), pine nuts are not " true nuts"; they are not botanical fruits, the seed not being enclosed in an ovary which develops into the fruit, but simply bare seeds—"gymnosperm" meaning literally "naked seed" (from and ). The similarity of pine nuts to some angiosperm fruits is an example of convergent evolution. Species and geographic spread In Asia, two species, in particular, are widely harvested: Korean ...
