The genusPerisoreus is a very small genus ofjays from theBoreal regions of North America andEurasia fromScandinavia to the Asian seaboard. An isolated species also occurs in north-westernSichuan of China. They belong to thePasserine order of birds in the familyCorvidae. Species ofPerisoreus jays are most closely related to the genusCyanopica.[2]
The genus was introduced by the French zoologistCharles Lucien Bonaparte in 1831.[3] Thetype species was subsequently designated as the Canada jay.[4] The name of the genus may come from theAncient Greekperisōreuō "to heap up" or "bury beneath". Alternatively it may be from the Latinperi- "very" or "exceedingly" andsorix, a bird ofaugury dedicated to Saturn.[5]
The genus contains three species.[6]
