Cyanocorax

Cyanocorax is a genus of New World jays, passerine birds in the crow family, Corvidae. The generic name is derived from the Greek words κυανος (kuanos), meaning "dark blue," and κοραξ (korax), meaning "raven".[1]

Species

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. Coincidentally, it is also the only species in this genus where the upperparts are not primarily blue or purplish.

The genus Cyanocorax was introduced by the German zoologist Friedrich Boie in 1826 with the plush-crested jay as the type species.[2][3] The name of the genus is from Ancient Greek kuanos "dark-blue" and korakos "raven" or "crow".[4]
