I mis-spoke, I meant to say "besides poaching". Trauma and lead poisoning are the two top causes of death for Eagles today. Trauma can be caused by many things, including gunshots, just as poaching can be done by poisoning. This is how most fish farms and game farms illegally eliminate Eagles preying on their crop. Our state DNR has been adamantly advising hunters to be aware of the possibility of lead poisoning from eating game harvested with lead projectiles, especially for children and pregnant/nursing women. Here's a good link from our neighbor Minnesota...... https://www.grandforksherald.com/northland-outdoors/6916763-Long-term-monitoring-shows-7-of-Minnesota-venison-laced-with-toxic-lead Deer hunting with firearms here runs from early October thru January. While lead ingestion is seasonal, it's a long season. Hard for Eagles to eat fish when the lakes, rivers and streams are frozen. Finding and eating frozen deer carcasses is easier. It takes a lead fragment the size of a grain of rice to kill an Eagle (One #5 pellet). Lead does not naturally leave the Eagles body, but will accumulate over long periods of time till it becomes lethal. This is the same with DDT. Turkey Vultures do get lead poisoning, but folks don't have the same emotions about them as they do Eagles and other Raptors. The gizzards in birds tends to grind down lead fragments and makes them easier to be absorbed and harder to eliminate thru fecal material than with mammals. Birds of prey also have very acidic stomachs as opposed to mammals and other birds.
