Turtledove

I watched TV with my pregnant wife choosing the satellite channel Star Movies yesterday night.It's showing the interesting childlike film Home Alone.I saw the little hero giving the money to the shop owner as a donation in the Xmas Eve.As a reward,the old shop owner,with whole white hair, gave the little boy two papery turtledoves.He told the boy that this kind of bird represents friendship and love,you can change hands to your friends or relatives.
So I got a new word,turtledove,a bird with a pleasant soft cry,whose males and females are supposed to love each other very much.----this explanation taken from Longman Dictionary of English Language & Culture(English-Chinese).
