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. (*).  ...  (*) Credo bene d’istituire questo sottogenere affine alle Nucifraghe pel Corvus infaustus di Siberia, il C. canadensis d’America, ed una nuova specie Artico-Americana anche più aberrante (e per conséguenza atta a servir di tipo) totalmente cinerea. Questo nuovo gruppo offre una decisa analogia colle Cinciallegre (Parus).”; "Perisoreus Bonaparte, 1831, Giorn. Arcadico, 49, p. 42. Type, by subsequent designation (Gray, 1840, List Gen. Birds, p. 37), Corvus canadensis Linnaeus." (Vaurie in Peters 1962, XV, 235).  
Var. Perisorius.

L. infaustus  unlucky, unfortunate, inauspicious  < in-  not; faustus  favourable, auspicious  < favere  to favour.
• "19. — 5.  C. infaustus nov. sp.   Cuculis (Cacomantis) sepulcralis Gray Proc. Z. Soc. 1860. p. 359." (Cabanis & Heine 1862); in some Indomalay cultures the cries of cuckoos are regarded as the portends of doom (subsp. Cacomantis variolosus).
• "This without doubt is that bird our common people call the Night-raven, and have such a dread of, imagining it cry portends no less than their death, or the death of some of their near Relations: For it flies in the night" (Willughby 1678); "153. NYCTICORAX INFAVSTVS.  THE NIGHT RAVEN." (T. Forster 1817) (syn. Nycticorax nycticorax).
• "48. CORVUS.  ...  infaustus.  12. C. dorso cinereo, rectricibus rufis: intermediis duabus cinereis, fascia nigricante.  Turdus rectricibus rufis: duabus intermediis cinereis fascia nigricante; proximis apice cinereis. Fn. svec. 187.  Merula saxatilis. Will. orn. 145. t. 36. Raj. av. 65. Alb. av. 3. p. 51. t. 55.  Habitat in Europæ alpinis sylvis.  Avis proterva, sæpe carnivora." (Linnaeus 1758).  Formerly the Siberian Jay was considered a bird of ill omen in Norway and in many parts of Sweden, being known locally as Olycksfågel misfortune bird.  However, in modern Scandinavia this jay is regarded with affection (Perisoreus).
