Task: Compare how the experience of war are shown in remains and one other poem

Based on this excerpt, the mockingbird symbolizes the softer side of nature, because unlike most wild creatures, it doesn’t harm human habitat.
The mockingbird is used to symbolize innocence - just like the bird is innocent and does nothing to harm others, the young protagonists of the books are kind and innocent, and often suffer because of it. It is a sin to kill someone's innocence, just like it is a sin to kill such a beautiful and harmless bird.
