Lead Poisoning in Swans and Waterfowl

How discarded fishing weights, shotgun pellets, and other lead sources poison swans and waterfowl, and campaigns for lead-free alternatives.

Key Facts

Lead poisoning kills thousands of swans and waterfowl annually in the UK and similar numbers across Europe and North America
Swans ingest lead fishing weights mistaking them for grit required for digestion — even a single weight can be fatal
Lead shotgun pellets deposited in wetlands are ingested by diving ducks and other species foraging in mud
Symptoms of lead poisoning include wing droop, neck weakness, and progressive neurological deterioration over days to weeks
Lead fishing weights are banned in many countries but enforcement and awareness remain incomplete

Welfare Considerations

Lead poisoning in swans and waterfowl is a fully preventable welfare harm caused by human activity. Individual swans that ingest lead fishing weights suffer a prolonged, distressing death over days to weeks as neurological function deteriorates. The suffering is intense and the cause entirely avoidable — effective non-lead fishing weights and shot are widely available. The welfare case for complete transition to lead-free alternatives in fishing and shooting is unambiguous. Progress has been made but compliance remains incomplete, and continuing education of anglers and shooters about the welfare impacts of lead is essential.

What You Can Do

Use only lead-free fishing weights and do not leave any fishing tackle on or near water
Advocate for mandatory lead-free ammunition and fishing weight requirements in your jurisdiction
Report swans or waterfowl showing signs of lead poisoning to wildlife rehabilitation organisations
Support wildlife charities providing emergency treatment for lead-poisoned birds
Engage with angling and shooting organisations about transitioning their members to lead-free alternatives
