These species do not form a single taxonomic group within the genus. There is no consistent distinction between "crows" and "ravens", and these appellations have been assigned to different species chiefly on the basis of their size, crows generally being smaller than ravens. In Europe, the word "crow" is used to refer to the [[carrion crow]] or the [[hooded crow]], while in North America it is used for the [[American crow]], [[fish crow]], or the [[northwestern crow]]. The largest raven species are the [[common raven]] and the [[thick-billed raven]]. ==Etymology== The term "raven" originally referred to the common raven, 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]]) ''hrafn''<ref>''Oxford English Dictionary'' entry for "raven."</ref> and [[Old High German]] ''(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]] ''*hrabanaz''.<ref>{{cite web| title=Raven| work=Online Etymology Dictionary| url=http://www.etymonline.com/index.php?term=raven| accessdate=2007-05-14}}</ref> Obsolete [[collective noun]]s for a group of ravens (or at least the common raven) include "unkindness"<ref>{{cite web|url=http://baltimorebirdclub.org/gnlist.html | title=Baltimore Bird Club.
