In Europe, 'magpie' is often used by English speakers as a synonym for the European Magpie, as there are no other magpies in Europe outside of the Iberian Peninsula. That bird was referred to as a 'pie' until the late 16th century when the feminine name 'mag' was added to the beginning. Magpies are believed to be among the most intelligent of animals: the European Magpie is one of the few animal species known to be able to recognize itself in a mirror test. According to analysis, magpies do not form the monophyletic group they are traditionally believed to bea long tail has certainly elongated (or shortened) independently in multiple lineages of corvid birds. Among the traditional magpies, there appear to be two distinct lineages: one consists of Holarctic species with black/white coloration and is probably closely related to crows and Eurasian jays. The other contains several species from South to East Asia with vivid coloration which is predominantly green or blue.
