What should I do if I encounter a black snake with a yellow head in the wild?

If you encounter a black snake with a yellow head in the wild, it is likely a non-venomous species called a black racer. You should calmly and slowly back away from the snake to give it space and avoid startling it. Do not try to touch or handle the snake, as it may become defensive. It is best to observe the snake from a safe distance and allow it to move away on its own.
