In this essay we have told about the origin of the little of this great novel and our interpretation of what it means. It as been amply demonstrated that the mockingbirds are certainly a big part of this story.
It is perhaps their long, solitary, mournful song which sometimes makes us reflect on ourselves. Or perhaps it is their simple innocence which relates to innocent children like Jem or Scout .
In the end, everyone grows up, Jem and Scout included, and so does innocence; and so, the mockingbird, although not literally shot and killed, dies.
