The proponents of banning lead want to do so because certian birds are supposed to ingest lead and die as a result. Their claim is based on a study in England where two loons were found to have lead sinkers in their crops. There have been NO such findings in the US or for that matter in the rest of the world. A ban on lead in fishing tackle is simply an Anti Fishing move.
Now, there are instances where animals shot with lead bullets have died and birds such as Eagles, Buzzards, and such have ingested the particles and have again died from the ingested lead. However, the incidence is very very small. To put it in perspective, the Wind Farms in Central and Northern California kill more raptors, specifically Golden Eagles and various hawks, per week than die from lead ingestion all year. California has instituted a no lead ammunition ban in areas where the California Condor ranges, you have to use copper ammo there.
In reality, the only place where lead from hunting has been a problem has been in the Waterfowl marshes and that has already been taken care of. Any other calls for the banning of lead, especially in fishing tackle is nothing more that Anti Fishing BS.
By the way, when I loose a jig, sinker, etc , it is usually in deep water, over 3-4 feet !! Don’t know of may birds that diver that deep looking for gravel for their crops. I am also not aware of any birds that would swallow a jig with a hook attached !! This is all BOVINE SCATOLOGY !!!
I am not sure why you feel there is no cases and studies in the USA, and why you feelit is small.
As far as Birds eating you fishing tackle, it is morethe birds eating the fish that are now toxic.
There is a lot on this on the net, here is just one:

Again, I am neither here nor there. I do again, see there being a non toxic exchange, but that is up to each one of us to feel the justification.
Unfortunately I do feel it will come down to a no questions asked ban some day.
Great post and way to kill a gloomy day.
