Spizaetus alboniger

The Blyth's hawk-eagle (Nisaetus alboniger) (earlier treated as Spizaetus)[2] is a medium-sized bird of prey. Like all eagles, it is in the family Accipitridae.

It can be found in the Malay Peninsula, Singapore, Sumatra and Borneo.[3] 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 50–60 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.
