In the novel, To Kill a Mockingbird, Harper Lee portrays Tom Robinson, Boo Radley and Jem as people with the mockingbird trait for several reasons. If you remember Miss Maudie's comment describing mockingbirds, she says, "Mockingbirds don't do one thing but make music for us to enjoy." She continues with "..they don't do one thing but sing their hearts out for us." She is describing the innocence of a bird who only sings, bringing pleasure to those willing to listen. Each of the three characters selected are also innocents, willing to help people, seeing the world as a positive place even if circumstances look differently. Tom is willing to help a terribly lonely girl who needs his help because her father will not, and is innocent of the crime of which he is accused. Boo Radley is the town recluse, hiding in his house, but willing to befriend the children with his small gifts and his rescue of them from Bob Ewell's attack. Jem is the innocent boy playing imaginary games and being a child until forced to give up his innocence in order to make sense of the trial and why his father would subject his family to the outcry of defending a black man. Each of these characters is like the mockingbird in the sense that they are all "singing their hearts out for us" in order for us to learn the lessons they can teach. We have to be willing to listen in order to learn the lessons of life these mockingbirds can teach us.
