A crow is a bird of the genus Corvus, or more broadly, a synonym for all of Corvus. The word "crow" is used as part of the common name of many species. The related term "raven" is not linked scientifically to any certain trait but is rather a general grouping for larger-sized species of Corvus. The collective name for a group of crows is a "murder".
These clever, curious birds have a reputation as thieves and pranksters. They have been known to fly off with all sorts of little shiny objects, including people's car keys. Pet crows have even learned to mimic, or imitate, human speech. Crows belong to the group of birds called songbirds.
