Corvid
Corvidae is a cosmopolitan family of oscine passerine birds that contains the crows, ravens, rooks, magpies, jackdaws, jays, treepies, choughs, and nutcrackers. In 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 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 ( Eurasian 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 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 AsiaCorvidae Retrieve ...

Songbird
A songbird is a bird belonging to the suborder Passeri of the perching birds (Passeriformes). Another name that is sometimes seen as the scientific or vernacular name is Oscines, from Latin ''oscen'', "songbird". The Passeriformes contains 5,000 or so speciesEdwards, Scott V. and John Harshman. 2013. Passeriformes. Perching Birds, Passerine Birds.

Songbirds form one of the two major lineages of extant perching birds (~4,000 species), the other being the Tyranni (~1,000 species), which are most diverse in the Neotropics and absent from many parts of the world. The Tyranni have a simpler syrinx musculature, and while their vocalizations are often just as complex and striking as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pyrrhocoracinae
A chough ( ) is any of two species of passerine birds that constitute the genus ''Pyrrhocorax'' of the Corvidae (crow) family. 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 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 and rocky sea-cliffs 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, especially in winter. Changes in ...

Corvus
''Corvus'' is a widely distributed genus of passerine birds ranging from medium-sized to large-sized in the family Corvidae. It includes species commonly known as crows, ravens, and rooks. The species commonly encountered in Europe are the carrion crow, hooded crow, common raven, and rook; those discovered later were named "crow" or "raven" chiefly on the basis of their size, crows generally being smaller. The genus name is Latin for "raven". The 46 or so members of this genus occur on all temperate continents except South America, and several islands. The ''Corvus'' genus makes up a third of the species in the family Corvidae. The members appear to have evolved in Asia from the corvid stock, which had evolved in Australia. The collective name for a group of crows is a "flock" or a "murder". Recent research has found some crow species capable of not only tool use, but also tool construction. Crows are now considered to be among the world's most intelligent animals with a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magpie
Magpies are birds of various species of the family Corvidae. Like other members of their family, they are widely considered to be intelligent creatures. The Eurasian magpie, for instance, is thought to rank among the world's most intelligent creatures, and is one of the few nonmammalian species able to recognize itself in a mirror test. Magpies have shown the ability to make and use tools, imitate human speech, grieve, play games, and work in teams. They are particularly well known for their songs and were once popular as cagebirds. In addition to other members of the genus '' Pica'', corvids considered magpies are in the genera '' Cissa'', '' Urocissa'', and '' Cyanopica''. Magpies of the genus ''Pica'' are generally found in temperate regions of Europe, Asia, and western North America, with populations also present in Tibet and high-elevation areas of Kashmir. Magpies of the genus ''Cyanopica'' are found in East Asia and the Iberian Peninsula. The birds called magpies in Au ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Crypsirininae
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 Southeast Asia is the geographical United Nations geoscheme for Asia#South-eastern Asia, southeastern region of Asia, consisting of the regions that are situated south of China, east of the Indian subcontinent, and northwest of the Mainland Au ....

Eurasian Magpie
The Eurasian magpie or common magpie (''Pica pica'') is a resident breeding bird throughout the northern part of the Eurasian continent. It is one of several birds in the crow family (corvids) designated magpies, and belongs to the Holarctic radiation of "monochrome" magpies. In Europe, "magpie" is used by English speakers as a synonym for the Eurasian magpie: the only other magpie in Europe is the Iberian magpie (''Cyanopica cooki''), which is limited to the Iberian Peninsula. Despite having a shared name and similar colouration, it is not closely related to the Australian magpie. The Eurasian magpie is one of the most intelligent birds. The expansion of its nidopallium is approximately the same in its relative size as the brain of chimpanzees, gorillas, orangutans and humans. It is the only non-mammalian species known to pass the mirror test. Taxonomy and systematics The magpie was described and illustrated by Swiss naturalist Conrad Gessner in his '' Historiae animali ...

Passerine
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 of their toes (three pointing forward and one back), which facilitates perching. With more than 140 families and some 6,500 identified species, Passeriformes is the largest order of birds and one of the most diverse clades of terrestrial vertebrates, representing 60% of birds.Ericson, P.G.P. et al. (2003Evolution, biogeography, and patterns of diversification in passerine birds ''J. Avian Biol'', 34:3–15.Selvatti, A.P. et al.

Tool Use By Animals
Tool use by non-humans is a phenomenon in which a non-human animal uses any kind of tool in order to achieve a goal such as acquiring food and water, Personal grooming, grooming, combat, defence, Animal communication, communication, Play (activity), recreation or animal architecture, construction. Originally thought to be a skill possessed only by humans, some tool use requires a sophisticated level of cognition. There is considerable discussion about the definition of what constitutes a tool and therefore which behaviours can be considered true examples of tool use. A wide range of animals, including mammals, birds, fish, cephalopods, and insects, are considered to use tools. Primates are well known for using tools for hunting or gathering food and water, cover for rain, and self-defence. Chimpanzees have often been the object of study in regard to their usage of tools, most famously by Jane Goodall, since these animals are frequently kept in captivity and are closely related t ...
