Cyanocorax
''Cyanocorax'' is a genus of New World jays, passerine birds in the family Corvidae. The generic name is derived from the Greek words κυανος (''kuanos''), meaning "dark blue," and κοραξ (''korax''), meaning "raven". It contains several closely related species that primarily are found in wooded habitats of Mexico and Central and South America, with the green jay just barely entering the United States. The genus ''Cyanocorax'' was introduced by the German zoologist Friedrich Boie in 1826, with the plush-crested jay as the type species. Species The genus contains 17 species: Some ornithologists treat the green jay and the Inca jay as conspecific Biological specificity is the tendency of a characteristic such as a behavior or a biochemical variation to occur in a particular species. Biochemist Linus Pauling stated that "Biological specificity is the set of characteristics of living organ ..., with ''C. yncas luxuosus'' as the green jay and ''C. yncas yncas'' as the ...

Corvidae
Corvidae is a cosmopolitan family of oscine passerine birds that contains the crows, ravens, rooks, jackdaws, jays, magpies, treepies, choughs, and nutcrackers. In colloquial English, they are known as the crow family or corvids. Currently, 133 species are included in this family. The genus ''Corvus'', including the crows, rooks, and ravens, 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 (European 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 higher 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 AsiaCor ...

Green Jay
The green jay (''Cyanocorax luxuosus'') is a species of the New World jays, and is found in Central America. Adults are about long and variable in colour across their range; they usually have blue and black heads, green wings and mantle, bluish-green tails, black bills, yellow or brown eye rings, and dark legs. The basic diet consists of arthropods, vertebrates, seeds, and fruit. The nest is usually built in a thorny bush; the female incubates the clutch of three to five eggs. This is a common species of jay with a wide range and the International Union for Conservation of Nature has rated its conservation status as being of "least concern". Taxonomy Some ornithologists treat the green jay as conspecific with the Inca jay of the Andes, with ''C. yncas luxuosus'' as the green jay and ''C. yncas yncas'' as the Inca jay. Description Green jays are in length. Weight ranges from . They have feathers of yellowish-white with blue tips on the top of the head, cheeks and nape, though s ...

Plush-crested Jay
The plush-crested jay (''Cyanocorax chrysops'') is a jay of the family Corvidae (which includes the crows and their many allies). It is found in central-southern South America: in southwestern Brazil, Bolivia, Paraguay, Uruguay, and northeastern Argentina, including southern regions of the Amazon Basin river systems bordering the Pantanal.

Distribution The range of the plush-crested jay extends from the Southern Region, Brazil with Uruguay and approaches the South Atlantic coast, but avoids the coast, approximating a 400 to 150 km coastal strip; the coastal-inland range extends 3500 km from São Paulo south to Rio Grande do Sul bordering Uruguay. The inland range continues in northwestern Uruguay and extends northwest through northern Argentina, Paraguay–Bolivia, and through the Pantanal at the southe ...

Cyanocorax Cayanus
The Cayenne jay (''Cyanocorax cayanus'') is a species of bird in the family Corvidae. It is found in Brazil, French Guiana, Guyana, Suriname, and Venezuela. Its natural habitats are subtropical or tropical moist lowland forest, subtropical or tropical dry shrubland, and heavily degraded former forest. In 1760 the French zoologist Mathurin Jacques Brisson included a description of the Cayenne jay in his ''Ornithologie'' based on a specimen collected in Cayenne, French Guiana. He used the French name ''Le geay de Cayenne'' and the Latin ''Garrulus Cayanensis''. 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 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 twelfth edition, he added 240 species th ...
