Chough
There are two species of passerine birds commonly called chough ( ) that constitute the genus ''Pyrrhocorax'' of the Corvidae (crow) family of birds. These are the red-billed chough (''Pyrrhocorax pyrrhocorax''), and the Alpine chough (or yellow-billed chough) (''Pyrrhocorax graculus''). The white-winged chough of Australia, despite its name, is not a true chough but rather a member of the family Corcoracidae and only distantly related. The choughs have black plumage and brightly coloured legs, feet, and bills, and are resident in the mountains of southern Eurasia and North Africa. They have long broad wings and perform spectacular aerobatics. Both species pair for life and display fidelity to their breeding sites, which are usually caves or crevices in a cliff face. They build a lined stick nest and lay three to five eggs. They feed, usually in flocks, on short grazed grassland, taking mainly invertebrate prey, supplemented by vegetable material or food from human habitation, esp ...

Red-billed Chough
The red-billed chough, Cornish chough or simply chough ( ; ''Pyrrhocorax pyrrhocorax''), is a bird in the crow family, one of only two species in the genus '' Pyrrhocorax''. Its eight subspecies breed on mountains and coastal cliffs from the western coasts of Ireland and Britain east through southern Europe and North Africa to Central Asia, India and China. This bird has glossy black plumage, a long curved red bill, red legs, and a loud, ringing call. It has a buoyant acrobatic flight with widely spread primaries. The red-billed chough pairs for life and displays fidelity to its breeding site, which is usually a cave or crevice in a cliff face. It builds a wool-lined stick nest and lays three eggs. It feeds, often in flocks, on short grazed grassland, taking mainly invertebrate prey. Although it is subject to predation and parasitism, the main threat to this species is changes in agricultural practices, which have led to population decline, some local extirpation, and range fra ...

Chough (Pyrrhocorax Pyrrhocorax) (W PYRRHOCORAX PYRRHOCORAX R1 C17)
There are two species of passerine birds commonly called chough ( ) that constitute the genus ''Pyrrhocorax'' of the Corvidae (crow) family of birds. These are the red-billed chough (''Pyrrhocorax pyrrhocorax''), and the Alpine chough (or yellow-billed chough) (''Pyrrhocorax graculus'').

Alpine Chough
The Alpine chough (), or yellow-billed chough (''Pyrrhocorax graculus'') is a bird in the crow family, one of only two species in the genus '' Pyrrhocorax''. Its two subspecies breed in high mountains from Spain eastwards through southern Europe and North Africa to Central Asia and Nepal, and it may nest at a higher altitude than any other bird. The eggs have adaptations to the thin atmosphere that improve oxygen take-up and reduce water loss. This bird has glossy black plumage, a yellow beak, red legs, and distinctive calls. It has a buoyant acrobatic flight with widely spread flight feathers. The Alpine chough pairs for life and displays fidelity to its breeding site, which is usually a cave or crevice in a cliff face. It builds a lined stick nest and lays three to five brown-blotched whitish eggs. It feeds, usually in flocks, on short grazed grassland, taking mainly invertebrate prey in summer and fruit in winter; it will readily approach tourist sites to find supplementary f ...

White-winged Chough
The white-winged chough (''Corcorax melanorhamphos'') is one of only two surviving members of the Australian mud-nest builders family, Corcoracidae, and is the only member of the genus ''Corcorax''. It is native to southern and eastern Australia and is an example of convergent evolution as it is only distantly related to the European choughs that it closely resembles in shape, and for which it was named. Taxonomy The white-winged chough was first described by French naturalist Louis Jean Pierre Vieillot in 1817 as ''Coracia melanorhamphos'', other names given include ''Pyrrhocorax leucopterus'' by Dutch zoologist Coenraad Jacob Temminck in 1820, and ''Corcorax australis'' by French naturalist René-Primevère Lesson in 1830. before the current name was settled by Gregory Mathews in 1912. The specific epithet is derived from the Ancient Greek words ''melano-'' 'black' and ''rhamphos'' 'beak'. It is placed in the family known as the mud-nest builders or Corcoracidae, written as G ...

Corcoracidae
Corcoracidae is a family of passerine birds known as the Australian mudnesters. The family has sometimes been called Struthideidae in the past; however, despite Struthideidae being an older name than Corcoracidae, the latter name takes precedence. It contains just two species in two genera, the white-winged chough (''Corcorax melanorhamphos'') and the apostlebird (''Struthidea cinerea''). Both are endemic to Australia. Distribution and habitat Both the Australian mudnesters are found in open habitat in eastern Australia, mostly open eucalypt woodlands and some forest that lacks a closed canopy. The apostlebird is more tolerant of arid habitats and is found in arid woodland and shrublands. Both species are tolerant of human modified habitats and will occupy farmlands and suburban areas, and even parks and gardens. Description The two mudnesters are medium-sized passerines, the apostlebird being smaller at around in length and the larger white-winged chough averaging . Their morph ...

Cornwall
Cornwall (; kw, Kernow ) is a historic county and ceremonial county in South West England. It is recognised as one of the Celtic nations, and is the homeland of the Cornish people. Cornwall is bordered to the north and west by the Atlantic Ocean, to the south by the English Channel, and to the east by the county of Devon, with the River Tamar forming the border between them. Cornwall forms the westernmost part of the South West Peninsula of the island of Great Britain. The southwesternmost point is Land's End and the southernmost Lizard Point. Cornwall has a population of and an area of . The county has been administered since 2009 by the unitary authority, Cornwall Council. The ceremonial county of Cornwall also includes the Isles of Scilly, which are administered separately. The administrative centre of Cornwall is Truro, its only city. Cornwall was formerly a Brythonic kingdom and subsequently a royal duchy. It is the cultural and ethnic origin of the Cornish dias ...

Corvidae
Corvidae is a cosmopolitan family of oscine passerine birds that contains the crows, ravens, rooks, jackdaws, jays, magpies, treepies, choughs, and nutcrackers. In colloquial English, they are known as the crow family or corvids. Currently, 133 species are included in this family. The genus ''Corvus'', including the crows, rooks, and ravens, makes up over a third of the entire family. Corvids (ravens) are the largest passerines. Corvids display remarkable intelligence for animals of their size, and are among the most intelligent birds thus far studied. Specifically, members of the family have demonstrated self-awareness in mirror tests (European magpies) and tool-making ability (e.g. crows and rooks), skills which until recently were thought to be possessed only by humans and a few other higher mammals. Their total brain-to-body mass ratio is equal to that of non-human great apes and cetaceans, and only slightly lower than that of humans.Birding in India and South AsiaCor ...

Hoopoe
Hoopoes () are colourful birds found across Africa, Asia, and Europe, notable for their distinctive "crown" of feathers. Three living and one extinct species are recognized, though for many years all of the extant species were lumped as a single species—''Upupa epops''. In fact, some taxonomists still consider all three species conspecific. Some authorities also keep the African and Eurasian hoopoe together but split the Madagascar hoopoe. The Eurasian hoopoe is common in its range and has a large population, so it is evaluated as Least Concern on The IUCN Red List of Threatened Species. However, their numbers are declining in Western Europe. Conversely, the hoopoe has been increasing in numbers at the tip of the South Sinai, Sharm el-Sheikh. There are dozens of nesting pairs that remain resident all year round. Taxonomy The genus ''Upupa'' was introduced in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae''. The type species is the ...

Pleistocene
The Pleistocene ( , often referred to as the ''Ice age'') is the geological Epoch (geology), epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing Great American Interchang ...

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
