Seven bald eagles admitted to one Pennsylvania rehab center. Most poisoned by lead. This isn’t random. Hunters for Eagle Conservation and Conservation Science Global focus on real-world actions that keep eagles out of rehab and in the sky where they belong.

At Avian Haven, most eagles admitted show some level of lead exposure linked to fragments from lead ammo. Sadly, Avian Haven recently lost a golden eagle to extreme lead levels, underscoring the ongoing risk. Officials in Maine are urging a shift to lead-free ammo.

We love the new US Forever stamps illustrated by David Sibley! They depict the life stages of Bald Eagles from hatchling to nestling, juvenile, subadult, and adult. It takes about 5 years for them to molt into their iconic white heads and start to claim breeding territories.

One of our tracked bald eagles, hatched in east-central IL, became our first tagged nestling in the project to breed at just 5 years old. Sadly, she was found grounded in IN last week. A necropsy will tell us more. Choosing lead-free ammo is one way hunters can help eagles!

Good news - USFWS expanded its Voluntary Lead-Free Ammunition Program to 13 national wildlife refuges in 12 states (OR, WI, NC, NJ, MD, WV, ID, MD, NH, NY, VT, and MA), up from 7 last year. Partnered with Conservation Science Global, it helps to further protect eagles from lead poisoning.

A bald eagle in Virginia was recently found with 3,000 µg/dL of lead in its blood — it died within a day. Lead fragments from ammo in carcasses poison eagles every deer season. Hunters can help by choosing copper rounds.

Since 2012, we've tracked 250+ bald eagles (146 as nestlings)! One female, originally caught in OK and now grown up and nesting in KS, is now heading north. In winter, eagles feed on gut piles, risking lead poisoning from ammo. Hunters can help by switching to lead-free.

Juvenile bald or golden eagle? 🦅 Look for: 🟤 Feathered legs = golden 🟤 Proportionally large bill = bald 🟤 Dihedral glide = golden | Flat wings = bald 🟤 Color: goldens = clean white wing patches, white tail base, dark breast | balds = messy mottling

While avian flu continues to receive nationwide attention, lead poisoning in eagles remains a significant challenge that also deserves coverage. 2 of the 3 bald eagles admitted to this center in just a few weeks had toxic lead levels from scavenging carcasses from animals shot with lead bullets.

Nearly 9 years ago, CSG trapped and tagged 31 Bald Eagles. One of them, a nestling named Doc, covered over 680,000 GPS locations in North America. On Feb 17, he was spotted fishing close to his nest site! Doc’s journey is far from over, and we can’t wait to see where his adventures take him next!
