Information: - Jays are several species of medium-sized, usually colorful and noisy, passerine birds in the crow family, Corvidae. The names "jay" and "magpie" are somewhat interchangeable, and the evolutionary relationships are rather complex. For example, the Eurasian magpie seems more closely related to the Eurasian jay than to the Oriental blue and green magpies, whereas the blue jay is not closely related to either. - Monochrome describes paintings, drawings, design, or photographs in one color or values of one color. A monochromatic object or image reflects colors in shades of limited colors or hues. Images using only shades of grey (with or without black or white) are called grayscale or black-and-white. However, scientifically speaking, monochromatic light refers to visible light of a narrow band of wavelengths (see spectral color). - Self-awareness is the capacity for introspection and the ability to recognize oneself as an individual separate from the environment and other individuals. It is not to be confused with consciousness in the sense of qualia. While consciousness is a term given to being aware of one's environment and body and lifestyle, self-awareness is the recognition of that awareness. - Corvidae is a cosmopolitan family of oscine passerine birds that contains the crows, ravens, rooks, jackdaws, jays, magpies, treepies, choughs, and nutcrackers. In common English, they are known as the crow family, or, more technically, corvids. Over 120 species are described. The genus "Corvus", including the jackdaws, crows, and ravens, makes up over a third of the entire family. - Eurasia is the combined continental landmass of Europe and Asia. The term is a portmanteau of its constituent continents. Located primarily in the Northern and Eastern Hemispheres, it is bordered by the Atlantic Ocean to the west, the Pacific Ocean to the east, the Arctic Ocean to the north, and by Africa, the Mediterranean Sea, and the Indian Ocean to the south. The division between Europe and Asia as two different continents is a historical and cultural construct, with no clear physical separation between them; thus, in some parts of the world, Eurasia is recognized as the largest of five or six continents. In geology, Eurasia is often considered as a single rigid megablock. However, the rigidity of Eurasia is debated based on the paleomagnet data. - Two species of chough ("") 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 Eurasian magpie or common magpie ("Pica pica") is a resident breeding bird throughout Europe, much of Asia and northwest Africa. It is one of several birds in the crow family designated magpies, and belongs to the Holarctic radiation of "monochrome" magpies. In Europe, "magpie" is used by English speakers as a synonym for the European magpie: the only other magpie in Europe is the Iberian magpie ("Cyanopica cooki"), which is limited to the Iberian peninsula. - The mirror test, sometimes called the mark test or the mirror self-recognition test (MSR), is a behavioural technique developed in 1970 by psychologist Gordon Gallup Jr. as an attempt to determine whether a non-human animal possesses the ability of self-recognition. The MSR test is the traditional method for attempting to measure self-awareness, however there has been controversy whether the test is a true indicator. - A crow is a bird of the genus "Corvus". The term "crow" is used both as part of the common name of many species, and collectively for all of "Corvus". - The treepies comprise four closely related genera (Dendrocitta, Crypsirina, Temnurus and Platysmurus) of long-tailed passerine birds in the family Corvidae. There are 11 species of treepie. 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. - A passerine is any bird of the order Passeriformes, which includes more than half of all bird species. A notable feature of passerines compared to other orders of Aves is the arrangement of their toes, three pointing forward and one back, which facilitates perching. Sometimes known as perching birds or, less accurately, as songbirds, the passerines form one of the most diverse terrestrial vertebrate orders, with over 5,000 identified species. It has roughly twice as many species as the largest of the mammal orders, the Rodentia. It contains more than 110 families, the second-most of any order of tetrapods (after Squamata, the scaled reptiles). The passerines contain several groups of brood parasites such as the viduas, cuckoo-finches, and the cowbirds. Most passerines are omnivorous, while the shrikes are carnivorous. - A raven is one of several larger-bodied species of the genus "Corvus". These species do not form a single taxonomic group within the genus. - Magpies are birds of the Corvidae ( crow ) family , including the black and white Eurasian magpie , which is considered one of the most intelligent animals in the world , and the only non-mammal species able to recognize itself in a mirror test . In addition to other members of the genus Pica , corvids considered as magpies are in the genera Cissa , Cyanopica and Urocissa . - The Holarctic is the name for the biogeographic realm that encompasses the majority of habitats found throughout the northern continents of the world, combining Wallace's Palearctic zoogeographical region, consisting of North Africa and all of Eurasia (with the exception of the southern Arabian Peninsula, Southeast Asia, and the Indian subcontinent), and the Nearctic zoogeographical region, consisting of North America north of Southern Mexico. These regions are further subdivided into a variety of ecoregions. Many ecosystems, and the animal and plant communities that depend on them, are found across multiple continents in large portions of this realm. The continuity of these ecosystems results from the shared glacial history of the realm. The floristic Boreal Kingdom corresponds to the Holarctic realm. - The "Corvida" were one of two "parvorders" contained within the suborder Passeri, as proposed in the Sibley-Ahlquist taxonomy, the other being Passerida. Standard taxonomic practice would place them at the rank of infraorder. What entity does 'magpie' has the relation 'instance of' with?
