Spizaetus alboniger Blyth's hawk-eagle (Nisaetus alboniger) (earlier treated as Spizaetus)[2] is a medium-sized bird of prey.

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.

The common name commemorates Edward Blyth (1810–1873), English zoologist and Curator of the Museum of the Asiatic Society of Bengal.
