CORVUS
(Corvidae; Ϯ Common Raven C. corax) L. corvus  raven. In fable the Raven was originally white but, despite its supposed gift of prophecy, was turned into a black bird for its treachery. The Common or Northern Raven is the largest species of passerine bird; "48. CORVUS.  Rostrum convexum, cultratum, basi pennis setaceis tectum.  Lingua cartilaginea bifida." (Linnaeus 1758); "Corvus Linnaeus, 1758, Syst. Nat., ed. 10, 1, p. 105. Type, by tautonymy, "Corvus", i.e. Corvus corax Linnaeus." (Blake & Vaurie in Peters, 1962, XV, p. 261).  This is the ninth diagnosed genus in avian taxonomy.  Linnaeus's Corvus comprised twelve species (C. Corax, C. Corone, C. frugilegus, C. Cornix, C.
