Pica (genus)

Pica is the genus of two to four species of birds in the family Corvidae in both the New World and the Old. They have long tails and have predominantly black and white markings. One species ranges widely from Europe through Asia, one occurs in western North America and the third is restricted to California. They are usually considered closely related to the blue and green magpies of Asia, but recent research suggests their closest relatives are instead the Eurasian crows.
