1)The theme is superstition.
In the book it said, “Some young birds come along, flying a yard or two at a time and lighting. Jim said it was a sign it was going to rain. He said it was a sign when young chickens flew that way, and so he reckoned it was the same way when young birds done it. I was going to catch some of them, but Jim wouldn’t let me. He said it was death. He said his father laid mighty sick once, and some of them catched a bird, and his old granny said his father would die, and he did.”
Jim’s superstitions range from small predictions to events of huge importance.
