Why do stags buck each other?

Stags, or male deer, engage in bucking behavior primarily as a display of strength and dominance during the rutting season. This behavior helps establish hierarchy among males and is often accompanied by antler clashes and vocalizations. By demonstrating their physical prowess, stags can deter rivals and attract potential mates, ensuring their reproductive success. Additionally, this behavior can serve as a way to assess the fitness of competitors without escalating to serious injury.
