FAE, a female bald eagle that nested at the Mystic Lakes on the Arlington-Medford border, is now at the center of a growing fight over rat poison after she was found dead near her nest in March. Tufts Wildlife Clinic, which examined the bird, confirmed that testing pointed to a familiar villain in recent raptor deaths. "Analysis of liver tissue was positive for three second-generation anticoagulant rodenticides," the clinic said, according to NBC Boston. The clinic added that internal hemorrhaging with no sign of traumatic injury supports a diagnosis of anticoagulant rodenticide toxicosis as the likely cause of death.
Wildlife officials say FAE's death is at least the fourth bald eagle in Massachusetts linked to rodenticide exposure since 2021, a tally that has alarmed local birders and rehabilitators, according to The Boston Globe. Observers reported FAE missing from the nest in mid-March, and she was taken to Tufts soon after. The loss echoes that of MK, an Arlington female that fell ill and later died in 2023, as detailed by Cambridge Day.
Where the Bills Stand
On Beacon Hill, the latest eagle death has given fresh urgency to efforts to rein in the strongest rodenticides, known as second-generation anticoagulant rodenticides, or SGARs. Lawmakers have filed measures that would restrict SGAR use statewide, including House Bill H.5217 and a Senate draft reflected in S.2721, both posted on the Massachusetts Legislature website and the Massachusetts Legislature website. The drafts would narrow professional uses, require reporting and set limited emergency exceptions for anticoagulant rodenticide application.
State Rep. James Hawkins, who has pushed these measures for several years, told NBC Boston he is confident the bills will get a vote and pass. For local rehabilitators and residents who watched FAE on the nest, the news has been more gut punch than policy point. Photographer Jodi Sylvester described the loss as cutting close to home, while Zak Mertz of the New England Wildlife Center warned that "their blood starts to not be able to clot anymore," describing how anticoagulant poisoning shows up in raptors.
Local Moves and Safer Options
Even before FAE's death, some cities and towns were already trying to get ahead of the problem. Municipalities and conservation groups have moved to limit SGARs on town property and to promote integrated pest management as an alternative, according to Mass Audubon. The group highlights recent local wins, including Newbury’s ban on rat poisons on town-owned land and a home-rule petition, and recommends sanitation, exclusion and trapping before chemical controls.
Animal-welfare organizations say multiple home-rule petitions and local bills would let towns bar or restrict SGAR use on public property, though those measures still need state approval, per the MSPCA-Angell. Advocates argue that combining municipal action with statewide rules would be the most effective way to reduce secondary poisoning that kills eagles, hawks and pets.
If the bills advance, supporters say the changes would limit routine commercial use of SGARs and create narrow exceptions for public-health emergencies, while advocates insist such limits are necessary to stop secondary poisoning. For now, the community that watched FAE's nest, along with lawmakers pressing for a ban, say her death has sharpened the debate over how Massachusetts balances pest control with wildlife protection.
