Summarize this article.

In early March 2023, Murphy, a bald eagle at the World Bird Sanctuary in Valley Park, Missouri, began to spend his entire day sitting on a makeshift nest inside his aviary. The behavior was not unusual in itself. Male bald eagles always help females during the incubation process. However, in this case, the 31-year-old bird was trying to hatch a rock!

Over the next few weeks, Murphy became increasingly protective of his "offspring." He would screech at his fellow bald eagles if they came close to the nest. To avoid any confrontation, Murphy was moved to a separate enclosure on April 4, 2023.

That same week, bird rescuers brought an eaglet into the sanctuary. The young bird had been stranded on the ground after a windstorm destroyed its nest. The sanctuary staff wanted to bond it with an eagle rather than a human. This would allow them to release the bird back into the wild when it was ready. Since Murphy was already showing paternal instincts, it made perfect sense to pair the eaglet with him.
