Its been a while since people ask me regarding the difference in plumage for this species. The other name would suggest it's plumage well which is Black and White Hawk Eagle. In black and white I would say this is one of the most spectacular Hawk Eagle in Malaysia. So here is some basic point to show their difference. To began with the sorting out of male and female were based on 5 nest. At least 4 nest show very consistency in this plumage. Though there is a need to have more documentation this would remain the best clue for us for the time being. The female bird which usually show streaking which extend lower, much more well arrange breast marking and much browner tail compare to greyer tail. Some individual especially older female would show reddish yellow eye but this is not seen in many individual. This feature require more research but for nest which was confirmed to be more then 8 years this feature was seen. Face always look sharper and flatter compare to male.

Male on the other hand show less well arrange marking and also streaking remain on upper breast and less continue to lower underpart of the body. Head are much rounder and typical bill appear somewhat smaller compare to female. See this picture

here. Another difference is sometimes male show darker and blacker upperpart compare to female where show more brownish.
