The spectacular crest often blows in the breeze. This is an adult or near-adult. The eye is already yellow, which happens at about nine months. Juveniles also have a more finely barred tail and wing feathers than this bird. The mixture of brown and black body feathers and wing coverts may be caused in part, by retained older feathers having been bleached by the sun (fide Joost Brouwer).
Seemingly all dark when perched, large white patches appear in the wings when in flight. This unique bird is the only member of the genus Lophaetus. Some authors, (e.g. 2nd edition of Howard and Moore) placed this species in the genus Spizaetus, a name now reserved for a group of Hawk-Eagles found only in the American tropics.
