Magpies are birds of the Corvidae (crow) family, including the black and white Eurasian magpie, which is considered one of the most intelligent animals in the world, and the only non-mammal species able to recognize itself in a mirror test (though a recent study suggests that giant manta rays can also recognize their own reflection. In addition to other members of the genus Pica, corvids considered as magpies are in the genera Cissa.
