The eagles were likely exposed to the poison when eating mice and rats, according to researchers.

(CNN)The majority of American eagles likely have rat poison in their systems, a new study reported Wednesday.

Anticoagulant rodenticide compounds, another name for rat poison, were found in 82% of the 133 eagles tested by researchers, according to a study published in the journal PLOS One. Of the 116 bald eagles tested, 96 were exposed to poison; and of the 17 golden eagles examined, 13 were exposed.

Researchers examined the carcasses of eagles in the United States between 2014 and 2018, and they could not establish how the poison got into the birds' systems.

In the United States, rat poison is commonly used when trying to eliminate rats and mice, Ruder said.

The poison causes blood clots, so if a bird showed evidence of internal bleeding with no other trauma on its body, the researchers classified it as death by rat poison.

Of the birds examined, 4% died from rat poison.

Rat poison and other chemical compounds should not be used to kill rodents, said Edwards, who is also a professor of organismic and evolutionary biology.

Humans are to blame for poisoning the eagles, Ruder said, and more research needs to be done to determine other possible negative side effects for the birds that have poison in their systems but don't die from it.

While Ruder's hypothesis is that the eagles ingest the poison by eating rats and mice, he said he'd like to confirm exactly how the birds ingest the poison.

When researchers can trace how the poison enters the birds' systems, Ruder said there should be more regulations in place to protect wildlife.
