What type of shot is prohibited for waterfowl hunting in the U.S.?

Lead shot is prohibited for waterfowl hunting in the U.S. due to its toxicity. When lead shot is used, it can be ingested by waterfowl while they forage in the water, leading to lead poisoning, which can be fatal. This has significant implications for wildlife populations and ecosystem health. To mitigate these risks, the use of non-toxic alternatives, such as steel or bismuth shot, has become standard practice in waterfowl hunting. The ban on lead shot reflects an effort to protect waterfowl species as well as the environment, ensuring that hunting practices are sustainable and responsible. This regulation is enforced federally under the Migratory Bird Treaty Act and has helped recover several waterfowl species that were previously declining due to lead poisoning.
