Broad-winged hawks protect their nests in a show of aggression (i.e. diving and chasing) towards any suspected threat, but they generally do not make physical contact. Predators of eggs and nestlings include raccoons, crows, porcupines, and American black bears. Adults have been known to fall to red-tailed hawks, great horned owls, bald eagles, and golden eagles. The hatchlings need 5–6 weeks before they are able to leave the nest. Some young, even after that time, remain in the area of the nest for several weeks more.
