Tens of thousands, maybe hundreds of thousands, of waterfowl die from lead poisoning in the UK every year.
Spent lead shot – the bits that missed their target, accumulate in the environment and are ingested from the sediments of lakes and rivers by ducks searching for food. The lead pellets accumulate in the birds’ gizzards and poison them.
Watch this video (first two minutes) to see the lead shot in a gizzard.
Non-toxic alternative ammunition is available.
