Choughs
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 bond, pair for life and display philopatry, 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 fro ...

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 ...

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 ...

Ornithology
Ornithology is a branch of zoology that concerns the "methodological study and consequent knowledge of birds with all that relates to them." Several aspects of ornithology differ from related disciplines, due partly to the high visibility and the aesthetic appeal of birds. It has also been an area with a large contribution made by amateurs in terms of time, resources, and financial support. Studies on birds have helped develop key concepts in biology including evolution, behaviour and ecology such as the definition of species, the process of speciation, instinct, learning, ecological niches, guilds, island biogeography, phylogeography, and conservation. While early ornithology was principally concerned with descriptions and distributions of species, ornithologists today seek answers to very specific questions, often using birds as models to test hypotheses or predictions based on theories. Most modern biological theories apply across life forms, and the number of scientists w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ancient Greek
Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic period (), and the Classical period (). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and 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 Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form approaches Medieval Greek. There were several regional dialects of Ancient Greek, of which Attic Greek developed into Koine. Dia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Onomatopoeia
Onomatopoeia is the process of creating a word that phonetically imitates, resembles, or suggests the sound that it describes. Such a word itself is also called an onomatopoeia. Common onomatopoeias include animal noises such as ''oink'', ''meow'' (or ''miaow''), ''roar'', and ''chirp''. Onomatopoeia can differ between languages: it conforms to some extent to the broader linguistic system; hence the sound of a clock may be expressed as ''tick tock'' in English, in Spanish and Italian (shown in the picture), in Mandarin, in Japanese, or in Hindi. The English term comes from the Ancient Greek compound ''onomatopoeia'', 'name-making', composed of ''onomato''- 'name' and -''poeia'' 'making'. Thus, words that imitate sounds can be said to be onomatopoeic or onomatopoetic. Uses In the case of a frog croaking, the spelling may vary because different frog species around the world make different sounds: Ancient Greek (only in Aristophanes' comic play ''The Frogs'') probably ...

Jackdaw
Jackdaws are two species of bird in the genus ''Coloeus'' closely related to, but generally smaller than, the crows and ravens (''Corvus''). ''Coloeus'' is sometimes treated as a subgenus of ''Corvus'', including by the IUCN.Madge & Burn (1994) vii. They have a blackish crown, wings and tail, the rest of the plumage being paler.Madge & Burn (1994) 136–138. The word ''Coloeus'' is New Latin, from the Ancient Greek for jackdaws: ' (). Taxonomy While some authors consider ''Coloeus'' a subgenus of ''Corvus'', others have classified ''Coloeus'' as a distinct genus in the family Corvidae. Following '' Birds of South Asia: The Ripley Guide'', the International Ornithological Congress has also reassigned the two jackdaw species from the genus ''Corvus'' to the genus ''Coloeus''. Species The species are the western jackdaw (''Coloeus monedula''), which breeds in the British Isles and western Europe, Scandinavia, northern Asia and Northern Africa, and its eastern counterpart, the Dauri ...
