DEFINITIONS

PERISOREUS
(Corvidae; Ϯ Grey Jay P. canadensis) Bonaparte 1831, considered the Grey Jay and the Siberian Jay P. infaustus allied to the nutcrackers Nucifraga and analogous to the tits Parus, and the name perhaps reflects their habit of hoarding acorns and other food  < Gr. περισωρευω perisōreuō  to heap up, bury beneath. However, Coues 1882, suggested the derivation L. peri-  very, exceedingly, and sorix, bird of augury dedicated to Saturn, the god originally placated by human sacrifice (v. infaustus), and this seems to have been reinforced by Bonaparte 1831: “Perisoreus; Nob.
