The changeable hawk-eagle (Nisaetus cirrhatus) is named because it shows a wide range of variation in plumage from pale to dark, varying with moult and age. Also known as the crested hawk-eagle, it is a medium-sized eagle with massive rounded wings. The pale-morph adult is dark brown above with a white breast overlaid with dark streaks. The juvenile is much paler, with cleaner white underparts and less extensive striping and barring anywhere on the body. The dark morph is dark all over with paler outer wing feathers. It is found in much of the Indian subcontinent and southeast Asia.
