These species do not form a single [[Taxon|taxonomic group]] within the genus. There is no consistent distinction between "[[crow]]s" and "ravens", and these appellations have been assigned to different species chiefly on the basis of their size, crows generally being smaller than ravens. The largest raven species are the [[common raven]] and the [[thick-billed raven]]. ==Etymology== The term "raven" originally referred to the [[common raven]] (''Corvus corax''), the [[type species]] of the genus ''Corvus'', which has a larger distribution than any other species of ''Corvus'', ranging over much of the [[Northern Hemisphere]]. The modern English word ''raven'' has cognates in all other [[Germanic languages]], including [[Old Norse]] (and subsequently [[Icelandic language|modern Icelandic]]) {{lang|non|hrafn}}<ref>''Oxford English Dictionary'' entry for "raven".</ref> and [[Old High German]] {{lang|goh|(h)raban}},<ref>{{Cite encyclopedia| title=Raven|encyclopedia=Oxford English Dictionary|editor=Simpson, J. |editor2=Weiner, E. | year=1989 |edition= 2nd| location=Oxford |publisher=Clarendon Press|isbn= 0-19-861186-2}}</ref> all of which descend from [[Proto-Germanic]] {{lang|gem|*hrabanaz}}.<ref>{{cite web| title=Raven| work=Online Etymology Dictionary| url=http://www.etymonline.com/index.php?term=raven| access-date=14 May 2007}}</ref> [[Collective noun]]s for a group of ravens (or at least the common raven) include "rave",<ref>{{Cite book|last=Lipton|first=James|url=https://books.google.com/books?id=AVNazQEACAAJ|title=An Exaltation of Larks|date=1991|publisher=Viking|isbn=978-0-670-30044-0|language=en}}</ref> "treachery",<ref>{{cite web|url=http://baltimorebirdclub.org/gnlist.html | title=Baltimore Bird Club.
