Magpies are passerine birds of the crow family, Corvidae. The names 'jay' and 'magpie' are to a certain extent interchangeable, although this does not accurately reflect the evolutionary relationship between these birds. For example, the Eurasian Magpie seems more closely related to the Eurasian Jay than to the Oriental Blue and Green Magpies, whereas the Blue Jay is not as closely related to either within the Corvid family.
