Jay
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 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 z ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Raven
A raven is any of several large-bodied passerine bird species in the genus '' Corvus''. These species do not form a single taxonomic group within the genus. There is no consistent distinction between crows and ravens; the two names are assigned to different species chiefly by size. The largest raven species are the common raven and the thick-billed raven; these are also the largest passerine species. Etymology The term ''raven'' originally referred to the common raven (''Corvus corax''), the widespread species of the Northern Hemisphere. The modern English word ''raven'' has cognates in all other Germanic languages, including Old Norse (and subsequently modern Icelandic) and Old High German , all of which descend from Proto-Germanic . Collective nouns for a group of ravens include a "conspiracy", a "treachery", a "rave" and an "unkindness"; in practice, most people use the more generic "flock".

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 ...

New World
The term "New World" is used to describe the majority of lands of Earth's Western Hemisphere, particularly the Americas, and sometimes Oceania."America."

Since the 16th century, the term "New World" has been used to describe the Western Hemisphere, often referred to as the Americas. Since the 18th century, it has come to represent the United States, which was initially colonial British America until it established independence following the American Revolutionary War.

Monophyletic
In biological cladistics for the classification of organisms, monophyly is the condition of a taxonomic grouping being a clade – that is, a grouping of organisms which meets these criteria: # the grouping contains its own most recent common ancestor (or more precisely an ancestral population), i.e. excludes non-descendants of that common ancestor # the grouping contains all the descendants of that common ancestor, without exception Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic'' grouping meets 1. but not 2., thus consisting of the descendants of a common ancestor, excepting one or more monophyletic subgroups. A '' polyphyletic'' grouping meets neither criterion, and instead serves to characterize convergent relationships of biological features rather than genetic relationships – for example, night-active primates, fruit trees, or aquatic insects. As such, these characteristic features of a polyphyletic grouping ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
