Description (Initial Observations): These great mutated bald eagles take their name from ancient human stories of giant birds that lived in hidden mountain lairs. With a wingspan of over 20 meters, these are the largest avian creatures known on Gamma Terra. They otherwise look much like their ancestors, with dark brown or black feathers and a white-feathered head. Their keening cry can be heard for miles around, and their talons can grasp and pick up a rakox with ease.

Reactions: No known interactions

Behavior: Behavior modeling incomplete

Behavior: Behavior not recorded

Society: Thunderbirds lead lonely lives, only coming together with others of their kind for mating. Once the young hatch, the male leaves the nest (and the area). A single thunderbird's territory can stretch for dozens of kilometers in all directions from its nest (usually nestled in a high mountain crag). It does not allow other large predators to hunt in its territory, taking on yexil, mantids, and even kamodos without fear.
