Blyth's Hawk-eagle

Description:

From Wikipedia: The Blyth's Hawk-Eagle (Nisaetus alboniger) (earlier treated as Spizaetus) is a medium-sized bird of prey. Like all eagles, it is in the family Accipitridae. It breeds in Peninsula Malaysia, Singapore, Sumatra, Borneo. It is a bird of open woodland, although island forms prefer a higher tree density. It builds a stick nest in a tree and lays a single egg. It is a fairly small eagle at about 51–58 cm in length. Adult has a thick white band on uppertail and undertail, all black above, black spotted breast, barred below. It has a prominent crest like the bazas. Juvenile is dark brown above, and has a light brown head and underparts. The common name commemorates Edward Blyth (1810–1873), English zoologist and Curator of the Museum of the Asiatic Society of Bengal.

Habitat:

Seen in the foothills behind the village of Lempur, on the edge of the Kerinci Seblat National Park, Sumatra, Indonesia.

Notes:

I'm not 100% sure on the ID, especially since I never saw a crest. But I'm not sure what else it could be.
