(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."
