The Oriental magpie (''Pica serica'') is a species of magpie found from south-eastern Russia and Myanmar to eastern China, Korea, Taiwan, Japan and northern Indochina. It is also a common symbol of the Korean identity, and has been adopted as the "official bird" of numerous South Korean cities, counties and provinces. Other names for the Oriental magpie include Korean magpie and Asian magpie.

with few if any green hues. They are the largest magpies. They have a rump plumage that is mostly black, with but a few and often hidden traces of the white band which connects the white shoulder patches in their relatives.[

In culture
In Korea, the magpie (까치, "kkachi") is celebrated as "a bird of great good fortune, of sturdy spirit and a provider of prosperity and development". In the same vein of bringing fortune and luck, Korean children were also taught that when you lose a tooth, to throw it on the roof singing a song for the magpie; 까치야 까치야 헌이 줄게. The bird will hear your song and bring you a new tooth.
