The fledging stage is reached at 25 to 34 days of age, though the offspring will return to the nest to be fed until they become independent around 8 weeks. Eggs and nestlings are preyed on, rarely, by raccoons, crows as well as other competing Cooper's hawks. Adults rarely fall prey to larger raptors, namely red-tailed hawks, great horned owls, peregrine falcons, prairie falcons, bald eagles, golden eagles, Eurasian eagle-owls and northern goshawks.[5]
