Just read that the Blackhawk county Iowa conservation people had an eagle die of lead poisoning. Bird tested several times the toxic dose.They went on to say that of the 130 eagles that they have tested 60 had died of lead poisoning. They say they get it from scavenging deer carcasses and from fish with lead in their systems. I do know that lead is not excreted from your body once it is in.I can't imagine that gallinaceous game birds could get enough in their systems though.
