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]
