Why does Boo Radley represent a mockingbird?

Boo Radley symbolizes prejudice. Just because he is an introverted character, due to his Father's rein on him as a child, he is pre-judged by the children of Maycomb; Scout, Jem and Dill, just because of his isolated trates.

He is said to be a, 'malevolent phantom'; which is the antithesis to what he turns out to be. The inhumane imagery illustrates the fear that surrounds him, and links to how he doesn't go to church and isn't connected with anyone in Maycomb.

Despite his isolation, Miss Maudie says the rumours are, '3/4 coloured folks and 1/4 Stephanie Crawford. This is a great quote in symbolizing what Boo Radley represents, as he is just a regular guy. Yet, due to the social divide at the time, you only tend to have a high social class if you are an active member of the community.
