Adults are sometimes hunted by bald eagles, peregrine falcons, great horned owls and northern goshawks. Northern goshawks normally only vocalize during courtship or the nesting season. Northern goshawks ("Accipiter gentilis") have reportedly killed both young and adult barred owl. In some cases, their larger cousins, northern goshawks, will prey on Cooper's hawks. Northern goshawks are usually opportunistic predators, as are most birds of prey. Mountain lions, Kaibab squirrels, and northern goshawks are found here. Its long wings are unlike the short wings of the "Accipiter" goshawks. For example, wood pigeon flocks are preyed upon by goshawks. Competition for northern goshawks can also come from mammalian carnivores. Northern goshawks can be found in both deciduous and coniferous forests. Twelve horses, eight dogs, two goshawks and two peacocks were also discovered in the grave. Even more sporadically attacked by goshawks, given this prey's nocturnal habits, are bats. Male northern goshawks are long and have a wingspan. In addition, about eight species of falcon have been identified in the foods of goshawks. Presumably, it hunted diurnal birds in a manner similar to goshawks.
