Just curious, but have the "scientist" done any studies of the effects of lead on migrating waterfowl & doves in Central & South America?? How have the so called negative effects of lead damaged these birds? They (the fowl) appear to be reproducing in record numbers and hunting with lead has been going on there for a long long time. Most of these fields, marshes and lakes that these birds are shot at see thousands upon thousands of more "lead" than probably any field in north America, due to the volume of shooting of course. Just food for thought.
