Magpie, Crow, Raven
Magpies are birds of the Corvidae family. Like other members of their family, they are widely considered to be intelligent creatures. The Eurasian magpie, for instance, is thought to rank among the world's most intelligent creatures and is one of the few nonmammalian species able to recognize itself in a mirror test. They are particularly well known for their songs and were once popular as cagebirds.
A crow is a bird of the genus Corvus. Crows are generally black in colour. The word "crow" is used as part of the common name of many species. The related term "raven" is not pinned scientifically to any certain trait, but is rather a general grouping for larger species of Corvus.
Jackdaws are two species of bird in the genus Coloeus closely related to, but generally smaller than, crows and ravens (Corvus). They have a blackish crown, wings, and tail, with the rest of their plumage being paler.
