Here i see many birds called "kkachi" (까치) similar to magpies found in England, One for Sorrow is a traditional children's nursery rhyme about magpies. It goes,

One for sorrow,
Two for joy,
Three for a girl,
Four for a boy,
Five for silver,
Six for gold,
Seven for a secret,
Never to be told.
Eight for a wish,
Nine for a kiss,
Ten for a bird,
You must not miss!
