There is legend that blue bird will bring happiness. most eastern people believe it, including Japanese.
I heard blue bird for the first time when there is famous movie (杀死一只知更鸟)，maybe it is a famous book. I can 't remember clearly.
What we often saw are sparrow who fly to our country yard. it is small and flexible to find food from people.
if you go to amimal zoo, there are many different birds which rarely saw in daily life.
I am familiar with waking up when birds sing the song, a full happy day.
