Giant Eagles are large, powerfully built birds of prey, with a heavy head and beak. They are frequently seen in The Heroes of Olympus, mainly used by the Romans for transporting and protecting Roman demigods.


When Prometheus betrayed Zeus and gave fire to the mortals, he was punished by being chained to a rock and having his liver being eaten by a giant eagle, the Caucasian Eagle , only for it to regrow and be eaten again the next day.

The Son of Neptune

They are seen during the War Games rescuing demigods who fall from the fortress, as well as being used for the aerial evacuation of injured demigods.

The Mark of Athena

They are seen hunting down the crew of the Argo II in groups, and assisting the Roman demigods as they try to capture them. Leo Valdez tries to throw the eagles off the trireme's scent by using Buford, the flying table, to create a false trail with the scent of Frank's jeans. However, this does not work and the Roman demigods from Camp Jupiter follow the crew to Charleston.

Three giant eagles deposited a Roman commando, including Octavian on the dock to confront Annabeth Chase, Piper McLean, and Hazel Levesque. The eagles continue to circle the location of the demigods, crying out and calling for reinforcements.


The eagles are very large and strong, being able to carry demigods in their talons. They are powerfully built. They are golden colored with a large beak and head.


The eagles track demigods like monsters, but at a faster rate. They are strong enough to hold a demigod by their talons.


  • Eagles are the sacred animal of Zeus/Jupiter.
  • An eagle is the standard of the Twelfth Legion Fulminata.
  • In some Roman paintings, they are shown as three-headed giant eagles.
  • During the founding of the United States of America, many people compared it to the Roman Republic, that's why the national bird is the bald eagle.
