What does sparrow symbolize in Silence! The Court is in Session?

There is a featured song in the play that tells a story about a conversation between a sparrow and a parrot. The sparrow is sorrowful because, as it explains to the parrot, someone has stolen her nest. A bird’s nest serves two functions that take on symbolic significance: it is the safe place called home, as well as the site where eggs are laid and nurtured into chicks. The song becomes symbolic of the theft of the safety of privacy which Benare no longer enjoys. It also indicates the fictional charge against the defendant—infanticide—along with the punishment of her sentencing for being found guilty: enforced abortion.
