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".
Crows are highly intelligent birds known for problem solving, tool use, and social behavior. Studies have shown that crows create and use tools, recognize and remember individual human faces, and share information with other crows about potential threats. Crows also live in social groups and communicate with one another using a variety of vocalizations.
