Waterfowl hunting kills tens of millions of ducks and geese annually worldwide, with welfare concerns including wounding rates, non-toxic shot requirements, and lead poisoning in non-hunted birds.
Waterfowl hunting presents welfare concerns both for the birds that are killed and for those that are wounded and lost. A duck or goose that is hit but not retrieved may survive for hours or days with serious injuries before dying. The transition from lead to non-toxic shot, while necessary for ecosystem reasons, has paradoxically increased wounding rates at range in some situations because of inferior ballistics. Lead poisoning from ingested shot pellets in wetland sediments continues to affect swans, geese, and other non-hunted species. Welfare improvements include better hunter marksmanship training, range limitation enforcement, and full transition to high-performance non-toxic shot types beyond basic steel.
