Corvus canadensis[1]
Linnaeus, 1766

The genus Perisoreus is a very small genus of jays from the Boreal regions of North America and Eurasia from Scandinavia to the Asian seaboard. An isolated species also occurs in north-western Sichuan of China. They belong to the Passerine order of birds in the family Corvidae. Species of Perisoreus jays are most closely related to the genus Cyanopica.[2]

The genus was introduced by the French zoologist Charles Lucien Bonaparte in 1831.[3] The type species was subsequently designated as the Canada jay.[4] The name of the genus may come from the Ancient Greek perisōreuō "to heap up" or "bury beneath". Alternatively it may be from the Latin peri- "very" or "exceedingly" and sorix, a bird of augury dedicated to Saturn.[5]
