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 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. (Wikipedia)
