Rodenticide & Its Impact on Birds

Rodenticide (rat poison) impacts more than just rats; it’s a death sentence for owls, hawks, eagles, and other birds of prey.

Raptors, for example, often eat poisoned rats or bring them back to their nests to feed their young.

Additionally, rats can often return to bait boxes and eat poison for several days before they die—creating an even more dangerous dose of poison for the hawk or owl.

When raptors eat poisoned prey, they unknowingly ingest fatal toxins. Nestlings, too, suffer the deadly consequences.

In fact, according to a 2020 study from Tufts Wildlife Clinic at Cummings School of Veterinary Medicine,
100% of red-tail hawks admitted to the clinic tested positive for exposure to rodenticides.

These risks are especially prevalent during nesting season, which begins in January for Great-Horned Owls and April for Red-Tailed Hawks. Once their chicks hatch, parents work around the clock to bring in food and often travel farther when more is needed—increasing their chances of ingesting rodenticide.

Being apex predators, birds of prey are vital to their ecosystems, and play a large role in controlling rodents on their own. Without them, humans would be faced with many more unwanted pests.
