Araven is any of several large-bodiedpasserinebird species in the genusCorvus. These species do not form a singletaxonomic group within the genus. There is no consistent distinction betweencrows and ravens; the two names are assigned to different species chiefly by size.
The largest species are thecommon raven and thethick-billed raven; these are also the largest passerine species.
The termraven originally referred to thecommon raven (Corvus corax), the widespread species of theNorthern Hemisphere.
The modern English wordraven has cognates in all otherGermanic languages, includingOld Norse (and subsequentlymodern Icelandic)hrafn[1] andOld High German(h)Raban,[2] all of which descend fromProto-Germanic*hrabanaz.[3]
Collective nouns for a group of ravens include a "conspiracy", a "treachery", a "rave" and an "unkindness";[4][5] in practice, most people use the more generic "flock".[6]
