A raven is one of several larger-bodied members of the genus Corvus. These species do not form a single taxonomic group within the genus, but share similar characteristics and appearances that generally separate them from other crows. The largest raven species are the common raven and the thick-billed raven.


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 modern Icelandic) hrafn and Old High German (h)raban, all of which descend from Proto-Germanic *hrabanaz.[2]

Obsolete collective nouns for a group of ravens (or at least the common raven) include "unkindness"[3] and "conspiracy".[4] In practice, most people use the more generic "flock".
