Peregrine falcons are birds of prey but they are not without their predators. Golden eagles and great horned owls are larger and both will attack peregrine falcons when given the chance. In the 1960s and 1970s, peregrine falcons’ numbers were dwindling and at first, no one knew why. It wasn’t because of their predators, golden eagles and great horned owls. It was because what they were eating—smaller birds—were eating insects that had been poisoned by the insecticide DDT.
The thing that endangered their species came from somewhere they could not have seen coming. Stay alert.
