Raven

Larger birds in the genus ''Corvus''

A raven is any of several large-bodied passerine bird species in the genus Corvus. These species do not form a single taxonomic group within the genus. There is no consistent distinction between crows and ravens; the two names are assigned to different species chiefly by size.

The largest species are the common raven and the thick-billed raven; these are also the largest passerine species.

Etymology

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) hrafn and Old High German (h)Raban, all of which descend from Proto-Germanic *hrabanaz.

Collective nouns for a group of ravens include a "conspiracy", a "treachery", a "rave" and an "unkindness"; in practice, most people use the more generic "flock".
