"What you cannot hear, Quey, is the third bird. She is quiet, quiet, listening to the male birds get louder and lounder still. And when they have sung their voices out, then and only then will she speak up. Then and only then will she choose the man whose song she liked better. For now she sits, and lets them argue: who will be the better partner, who will give her better seed, who will fight for her when times are difficult" (Gyasi, 53)
Reference to the silence voices of history? Queys sexuality sitting silent until he can get a chance to act upon it.
