The term raven originally referred to the common raven (Corvus corax), the widespread species of the Northern Hemisphere.
The modern English word raven has cognates in all other Germanic languages, including Old Norse (and subsequently modern Icelandic) hrafn1 and Old High German (h)Raban,2 all of which descend from Proto-Germanic *hrabanaz.3
Collective nouns for a group of ravens include a "conspiracy", a "treachery", a "rave" and an "unkindness";45 in practice, most people use the more generic "flock".6
