It builds a stick nest in a tree and lays a single egg.

It is a fairly small eagle at about {{Convert|50–60|cm|in|abbr=on}} in length. The 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.
