Jays
Jays are a paraphyletic grouping of passerine birds within the family Corvidae. Although the term "jay" carries no taxonomic weight, most or all of the birds referred to as jays share a few similarities: they are small to medium-sized, usually have colorful feathers and are quite noisy. These superificial characteristics set them apart from most other corvids such as crows, ravens, jackdaws, rooks and magpies, which are larger and have darker plumage. Many so-called "jays" are genetically closer to these other corvids than other jays, however. Systematics and species Jays are not a monophyletic group. Anatomical and molecular evidence indicates they can be divided into a New World and an Old World lineage (the latter including the ground jays and the piapiac), while the grey jays of the genus ''Perisoreus'' form a group of their own.http://www.nrm.se/download/18.4e32c81078a8d9249800021299/Corvidae%5B1%5D.pdf PDF fulltext The black magpies, formerly believed to be related to ...

Eurasian Jay
The Eurasian jay (''Garrulus glandarius'') is a species of passerine bird in the crow family Corvidae. It has pinkish brown plumage with a black stripe on each side of a whitish throat, a bright blue panel on the upper wing and a black tail. The Eurasian jay is a woodland bird that occurs over a vast region from western Europe and north-west Africa to the Indian subcontinent and further to the eastern seaboard of Asia and down into south-east Asia. Across this vast range (biology), range, several distinct racial forms have evolved which look different from each other, especially when comparing forms at the extremes of its range. The bird is called jay, without any epithets, by English speakers in Great Britain and Ireland. Taxonomy and systematics The Eurasian jay was Species description, formally described by the Swedish naturalist Carl Linnaeus in 1758 in the 10th edition of Systema Naturae, tenth edition of his ''Systema Naturae'' under the binomial nomenclature, binomial nam ...

Jackdaw
Jackdaws are two species of bird in the genus ''Coloeus'' closely related to, but generally smaller than, crows and ravens ('' Corvus''). They have a blackish crown, wings, and tail, with the rest of their plumage paler.Madge & Burn (1994) 136–138. The word ''Coloeus'' is Neo-Latin, from the Ancient Greek for jackdaws: ' (). They come from Asia, Europe, Africa and Siberia (the one not in Asia?). 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 eastern species is smaller than the western jackdaw, and in eastern adults, the pale areas of the plumage are almost white, whereas in the western bird, these areas are pale grey. The iris is pale in western jackdaw and dark ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corvidae
Corvidae is a Cosmopolitan distribution, cosmopolitan Family (biology), family of Songbird, oscine passerine birds that contains the crows, ravens, Rook (bird), rooks, magpies, jackdaws, jays, treepies, choughs, and Nutcracker (bird), nutcrackers. In Colloquialism, colloquial English, they are known as the crow family or corvids. Currently, 139 species are included in this family. The genus ''Corvus'' containing 50 species makes up over a third of the entire family. Corvids (ravens) are the largest passerines. Corvids display remarkable Animal cognition, intelligence for animals of their size, and are among the most Bird intelligence, intelligent birds thus far studied. Specifically, members of the family have demonstrated self-awareness in mirror tests (Eurasian magpies) and Tool use by animals, tool-making ability (e.g. crows and rooks), skills which until recently were thought to be possessed only by humans and a few other mammals.

Cyanocorax
__NOTOC__ ''Cyanocorax'' is a genus of New World jays, passerine birds in the family Corvidae. It contains several closely related species that primarily are found in wooded habitats, chiefly in lowland tropical rainforest but in some cases also in seasonally dry forest, grassland and montane forest. They occur from Mexico through Central into southern South America, with the green jay and brown jay just entering the United States in southernmost Texas, ad the Azure and Plush-crested jays occurring southwards to the lower Paraná River basin. This genus is considered especially close to ''Cyanolyca'', an upland radiation occurring throughout the American Cordillera from Mexico to Peru and Bolivia, who look very similar to the blue-and-black species of ''Cyanocorax'' except for being a bit smaller. The North American blue jay genera ''Aphelocoma, Cyanocitta'' and '' Gymnorhinus'' seem to be slightly less closely related. ''Cyanocorax'' jays are generally black-and-blue, often ...

Lanceolated Jay
The black-headed jay or lanceolated jay (''Garrulus lanceolatus'') is roughly the same size as its close relative the Eurasian jay, but a little more slender overall except for the bill which is slightly shorter and thicker. The top of the head is black and it has a more obvious crest too and a longer tail. It ranges from eastern Afghanistan eastwards, across the Himalayas, from India to Nepal and Bhutan. It occurs in wooded country with large areas of open ground rather than dense forest. It also occurs in some cultivated areas and even near villages as long as there are enough trees and scrubland nearby. It feeds both on the ground and in trees, and takes virtually the same wide range of plant and animal foods as its close relative, including eggs and nestlings, as well as scraps near human habitation. It nests in trees and suitable bushes and in this resembles the Eurasian jay in every respect. their nests are made of sticks plastered together with mud and lined with weeds an ...

Peanut Thief (7184679351)
The peanut (''Arachis hypogaea''), also known as the groundnut, goober (US), goober pea, pindar (US) or monkey nut (UK), is a legume crop grown mainly for its edible seeds. It is widely grown in the tropics and subtropics by small and large commercial producers, both as a grain legume and as an oil crop. Atypically among legumes, peanut pods develop underground; this led botanist Carl Linnaeus to name peanuts ''hypogaea'', which means "under the earth". The peanut belongs to the botanical family Fabaceae (or Leguminosae), commonly known as the legume, bean, or pea family. Like most other legumes, peanuts harbor symbiotic nitrogen-fixing bacteria in root nodules, which improve soil fertility, making them valuable in crop rotations. Despite not meeting the botanical definition of a nut as "a fruit whose ovary wall becomes hard at maturity," peanuts are usually categorized as nuts for culinary purposes and in common English. Some people are allergic to peanuts, a potent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Treepie
The treepies (known also as crypsirinines from the subfamily's name, Crypsirininae) comprise four closely related genera (''Dendrocitta'', ''Crypsirina'', ''Temnurus'' and ''Platysmurus'') of long-tailed passerine birds in the family Corvidae. There are 12 species of treepie. Some treepies are similar to magpies. Most treepies are black, white, gray or brown. They are found in Southeast Asia. They live in tropical forests. They are highly arboreal and rarely come to the ground to feed. Species Following Ericson ''et al.'' (2005), the black magpies are placed with the treepies: References * Ericson, Per G.

Piapiac
The piapiac (''Ptilostomus afer'') is an African bird in the crow family, and is the only member of the genus ''Ptilostomus''. It is most closely related to the Central Asian ground jays. Taxonomy In 1760 the French zoologist Mathurin Jacques Brisson included a description of the piapiac in his ''Ornithologie'' based on a specimen collected in Senegal. He used the French name ''La pie du Sénégal'' and the Latin ''Pica Senegalensis''. The two stars (**) at the start of the section indicates that Brisson based his description on the examination of a specimen. Although Brisson coined Latin names, these do not conform to the binomial nomenclature, binomial system and are not recognised by the International Commission on Zoological Nomenclature. When in 1766 the Swedish naturalist Carl Linnaeus updated his ''Systema Naturae'' for the 12th edition of Systema Naturae, twelfth edition, he added 240 species that had been previously described by Brisson. One of these was the piapiac. Linn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ground Jay
The ground jays or ground choughs belong to a distinct group of the passerine order of birds in the genus ''Podoces'' of the crow family Corvidae. They inhabit high altitude semi-desert areas from central Asia to Mongolia. Ground jays show adaptations to ground living such as long, strong legs adapted to fast running and the ability to leap and bound onto boulders and rocks with great agility. Their long, curved thick bills are adapted for digging and probing. While capable of flight (which they do infrequently and relatively weakly), they prefer running, and will readily perch on trees and bushes also. Species list The ground tit (''Pseudopodoces humilis''), previously Hume's ground jay, has changed its placement within the Passeriformes A passerine () is any bird of the order Passeriformes (; from Latin 'sparrow' and '-shaped') which includes more than half of all bird species. Sometimes known as perching birds, passerines generally have an anisodactyl arrangement ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Old World
The "Old World" () is a term for Afro-Eurasia coined by Europeans after 1493, when they became aware of the existence of the Americas. It is used to contrast the continents of Africa, Europe, and Asia in the Eastern Hemisphere, previously thought of by the Europeans as comprising the entire world, with the "New World", a term for the newly encountered lands of the Western Hemisphere, particularly the Americas. Etymology In the context of archaeology and world history, the term "Old World" includes those parts of the world which were in (indirect) cultural contact from the Bronze Age onwards, resulting in the parallel development of the early civilizations, mostly in the temperate zone between roughly the 45th and 25th parallels north, in the area of the Mediterranean, including North Africa. It also included Mesopotamia, the Persian plateau, the Indian subcontinent, China, and parts of Sub-Saharan Africa. These regions were connected via the Silk Road trade route, and ...
