Traditionally loved by the Korean people, the magpie is believed to be an auspicious bird and a messenger of good news. According to a folktale, magpies formed a bridge to help two star-crossed lovers to reunite. It was also chosen as the national bird of Korea in 1964, getting overwhelming votes in a national contest.
