The tail has three wide gray bands and is tipped with white, while the underwing and thighs are barred black and white. The head is light gray with a blackish crest that is raised when the bird feels threatened; it may also serve to focus sound, similar to an owl’s facial disc. The beak is dark gray with a paler cere and the eyes are gray-brown. Feet and legs are light yellow—the talons are black, and can be up to 7 cm long.
It also possesses the largest talons of any living eagle.
