Nisaetus bartelsi (Javan Hawk-Eagle)

Synonyms: Spizaetus bartelsi

Wikipedia Abstract

The Javan hawk-eagle (Nisaetus bartelsi) (earlier placed in Spizaetus) is a medium-sized, approximately 60 cm long, dark brown raptor in the family Accipitridae. Its head and neck are rufous and it is heavily barred black below. This majestic and intricately patterned eagle has a long, black crest on its head; this crest is held almost vertically and is tipped with white. The crown is black, topping a chestnut head and nape. The back and wings are dark brown, fading to a lighter brown tail which has wide cream stripes. The throat is creamy white with a black stripe, running to the whitish breast and underparts, which are heavily barred with chestnut. Juvenile birds are similar in colour, but have plainer underparts and a duller head. The sexes are similar.
