Raven
A raven is any of several larger-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 based on their size.The largest raven species are the common raven and the thick-billed raven; these are also the largest passerine species.
