Raven
Template:Short description Template:About {{#invoke:other uses|otheruses}} Template:Use dmy dates
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 raven species are the common raven and the thick-billed raven; these are also the largest passerine species.
EtymologyEdit
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) {{#invoke:Lang|lang}}<ref>Oxford English Dictionary entry for "raven".</ref> and Old High German {{#invoke:Lang|lang}},<ref>Template:Cite encyclopedia</ref> all of which descend from Proto-Germanic {{#invoke:Lang|lang}}.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
Collective nouns for a group of ravens include a "conspiracy", a "treachery", a "rave" and an "unkindness";<ref>Template:Cite book</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> in practice, most people use the more generic "flock".<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
