"Prisoner Bird" is a song written by Ichiro, composed by Zhang Yu, arranged by Tu Ying and sung by Peng Ling. It was included in the album Prisoner's Birds released by Peng Ling on May 1996.

Part of the lyrics are as follows: I am like a dispensable shadow, watching you lying coldly. This sultry city can't tolerate my infatuation. What makes you so obsessed with such arrogance? I am like a dispensable shadow, exchanging sad thoughts with loneliness, and I can do nothing about love. In this tasteless day, tears are the only luxury. I am a bird imprisoned by you, and I have forgotten how high the sky is.
