2 bald eagles that died at Nova Scotia rehab centre had been exposed to lead
The recent deaths of two bald eagles at the Cobequid Wildlife Rehabilitation Centre near Hilden, N.S. serve as a stark reminder of the dangers of lead poisoning in wildlife. The eagles, brought in on January 20, were found to have high levels of lead toxicity, likely acquired from scavenging on animals shot with lead ammunition during the winter months.
Jessica Rock, a volunteer veterinarian at the centre, explained that lead exposure is a prevalent issue in wildlife globally, with bald eagles particularly vulnerable due to their reliance on scavenging in colder temperatures. Even a tiny piece of lead, smaller than a grain of rice, can be fatal to an adult bald eagle.
Rock emphasized the importance of using lead-free alternatives, such as copper ammunition, when hunting to prevent further incidents of lead poisoning in wildlife. While there is no ban on lead ammunition in Nova Scotia, educating hunters and raising awareness about the risks associated with lead exposure remains crucial.
The centre conducts regular testing on bald eagles, with alarming results showing that a significant number of birds have elevated lead levels in their blood. Symptoms of lead poisoning in bald eagles can include staggering, difficulty flying, lack of depth perception, paralysis, and wheezing sounds.
In addition to the two eagles that tragically died from lead poisoning, the centre is currently treating three other birds—two bald eagles and a turkey vulture—recovering from similar cases. The centre recommends burying remains of animals shot with lead ammunition to reduce the risk to scavenging birds like eagles.
By spreading awareness about the dangers of lead poisoning in wildlife and promoting the use of lead-free alternatives, we can help protect these majestic birds and prevent further tragedies. It is essential for hunters and outdoor enthusiasts to prioritize the conservation of our natural environment by choosing environmentally-friendly practices.
