An overwhelming majority of America’s eagles tested positive for rat poison in study published by Journal Plos One.
Researchers found that 96 of 116 deceased bald eagles they tested had the toxic chemical in their systems. Among golden eagles, 13 or 17 big birds had rat poison in their systems.
The study stated that rat poison was the cause of death in 4% of the eagles studied by researchers. It’s believed that eagles carrying the poison contracted it through prey that had consumed poison, but that couldn’t be proven.
The study’s authors listed “exposure to anticoagulant rodenticides,” also known as rat poison, to be a threat to the existence of raptors. Pest control chemicals in cities, suburb and rural areas were listed at possible reasons for the findings in the study, which was published Wednesday.
