Sad message
We have sad news. Hercules, the bald eagle who dozens of people from both sides of the Delaware River spent days trying to help, passed away overnight shortly after he was rescued.
We took a while to update social media about Hercules because we wanted to let Steve – who made the call to us about an eagle in distress and then sat with Hercules through a rain storm – know first. And also because we wanted to give his passing the time and attention it deserved, and make an effort to prevent this from happening to other animals.
Due to his high lead levels, and the lack of any other obvious contributing factors, we believe lead poisoning killed Hercules. It is not news that lead is toxic. Lead paint was banned in 1978 because of the significant health problems, including brain damage, it can cause in children. Lead shot was banned for hunting waterfowl a little over a decade later because of the negative impact on wildlife and the environment. And in 1996, the use of leaded gasoline in the U.S. was prohibited because of the hazards it can cause.
For eagles and other birds, symptoms of lead poisoning include brain swelling, respiratory distress, muscle weakness, dehydration, cramping, starvation, kidney and liver damage, and seizures. There is related neurological damage as well, including loss of coordination, impaired vision and nerve function, with the bird appearing to stagger or displaying difficulty standing. This exactly fits the reports we received of Hercules rocking on his talons, having difficulty standing, and appearing grounded.
There are two principal ways that eagles (and other animals) get lead poisoning – by eating fish which have swallowed lead sinkers, lures, etc., or by eating carrion (including leftover gut piles) which contain lead shot. Even the tiniest fragment of lead can be lethal to an eagle, as it is dissolved in the stomach acid and then transferred into the bloodstream and organs. The lead gets absorbed, not passed out, and it accumulates in the liver and kidneys, and then is deposited in the bones.
It is not a gentle end.
So we are asking the hunters and fishers out there to consider alternatives to lead ammunition and tackle. In particular, copper ammunition has become more popular in recent years, is just as effective, is not toxic the way that lead is, and is not significantly more expensive than lead-based ammo (don’t take our word for it – there is a link to an article by Back Country Hunters & Anglers in the comments, with a list of available non-lead ammunition). For fishing tackle, a 7-second Amazon search brings up scores of lead-free options (and we have a link to a list of other retailers in the comments as well).
We wish we had better news about Hercules, that we had been able to save him. But if even a handful of people convert to lead-free ammunition and fishing tackle after learning about Hercules, at least his passing will have made a difference.
