Bald eagles, like many birds of prey, exhibit behaviors related to their offspring that can seem harsh but are rooted in survival instincts. When a chick dies in the nest, bald eagles typically remove it to maintain cleanliness and prevent the spread of disease or parasites. This behavior also helps to avoid attracting predators that might be drawn to the scent of decay. In some cases, the dead chick may be carried away from the nest and dropped, or it may be consumed by the adult eagles or other siblings, a practice known as necrophagy, which provides nutrients and reduces waste. While these actions may appear callous, they are essential for the health and safety of the remaining chicks and the overall success of the brood.
