The lesser fish eagle is similar in plumage but smaller and the Pallas's fish eagle shares the same habitat and feeding behaviour but is larger with longer wings and darker underparts.

As juveniles mature subterminal band becomes more prominent, head becomes greyer and loses streaking becoming uniformly brown.
