Common predators that eat coyotes include bears, cougars, wolves, mountain lions and other coyotes. Dogs and eagles are also opportunistic predators against coyote pups.
In the wild, coyotes also face diseases, competition for food, parasites and social stress that lead to population control. Humans are another threat for coyotes, especially along busy roads, where coyotes are struck and killed by passing vehicles.
Coyotes breed in the late winter, so the pups are typically born between early April and late May after a 63-day gestation period. While the pups are young and still in the den, the adult coyotes can become more aggressive to protect the area.
