It's a real serious problem back in the UK, which makes me think it will be the same here - has anybody picked up on this yet ?
Two years ago on Loch Eye, near Inverness Scotland over 200 Greylag Geese and 100 mute Swans died of lead poisoning in a single incident when water levels fell on the loch and birds were taking up large quantities of lead shot which had accumulated from years of duck hunting.
There are moves to replace the lead shot in cartridges with steel. Duck hunters are resisting as the killing distance is reduced by about 15%. Some other alloys of magnesium are being field tested - not on live birds.
There used to be a similar problem with anglers losing lead weights which were poisoning waterfowl. Once a good alternative was found, a informative PR campaign which involved national organisations, angling journalists, etc helped the majority of the UK's 2 million anglers make the change.
