Rook, with the emphasis on "TODAY", I can agree with you. Lead shot bans for waterfowling is about all that was/is needed. I don't know if raptor ingestion of lead in prairie dog towns has an effect on raptor populations or not. Never seen, or looked for any literature on it. Have you? I'd be interested in a few citations if you know of any.

Lead in water supplies is not, never was, an issue.

Lead in Condors from carcasses is an issue. But that is only condors and only so long as their populations are so small.
