Eagles protect their nests and young from predators through various means such as building their nests in high and remote locations, using their keen eyesight to detect threats from a distance, and actively defending their nest by dive-bombing and using their talons to ward off intruders. Additionally, both parent eagles work together to guard their nest and young, taking turns watching over them while the other hunts for food. This coordinated effort helps ensure the safety and protection of the eagle family from potential predators.
