A nest in a tree symbolizes how high it is up in the tree that separates it from other animals or birds. The young birds grow up to live and be free flying from the nest to out In the open.

Never land is symbolic because In the story of Peter Pan the island is where Peter Pan travels to with the children . Therefore They go because they don't want to be controlled by their parents, they want to be lost boys. They can be and do whatever they want to.
