A giant eagle typically attacks from a great height, diving earthward at tremendous speed. When it cannot dive, it uses its powerful talons and slashing beak to strike at its target's head and eyes.
A solitary giant eagle is typically hunting or patrolling in the vicinity of its nest and generally ignores creatures that do not appear threatening. A mated pair will attack in concert, making repeated diving attacks to drive away intruders, and will fight to the death to defend their nests or hatchlings.
Skills: Giant eagles receive a +4 racial bonus to Spot checks during daylight hours.
