Whhat are deer?

In the story "Migration," deer symbolize Mother Nature. The human beings depicted in this chapter have been living unnaturally. They have retreated into their homes where they live each and every day by not stepping into fresh air or natural sunlight. With the absence of people, the deer have returned to a more natural way of living, with undisturbed migration routes and the ability to graze for food wherever they wish. The narrator sees this juxtaposition. He sees the stark differences between how his family and he are living and how the deer are living. The deer appear majestic on the street. They are behaving naturally, as intended. It is the humans in this story who have rejected Mother Nature and, by eliminating them from the equation, the rest of Mother Nature can go back to a more normal state.
