The Javan Hawk-Eagle, Nisaetus bartelsi (earlier placed in Spizaetus[2]) is a medium-sized, approximately 61 cm long, dark brown raptor in the family Accipitridae. Its head and neck are rufous and it is heavily barred black below. It has a long black crest with a white tip. The sexes are similar. The young is duller and has unmarked underparts.

An Indonesian endemic, the Javan Hawk-Eagle occurs in humid tropical forests of Java. Its range in East Java includes Sempu Island, Bromo Tengger Semeru National Park, Meru Betiri National Park and Alas Purwo National Park. It can also be seen in captivity in zoos like Kebun Binatang Bandung[3]

The Javan Hawk-Eagle is believed to be monogamous. The female usually lays one egg in a nest high on top of a forest tree. The diet consists mainly of birds, lizards, fruit bats and mammals.

The Javan Hawk-Eagle is the national bird of Indonesia, where it is commonly referred to as Garuda, from the bird-like creatures in Hindu and Buddhist myths. The scientific name commemorates Hans Bartels.

Because of the plumage variability of Spizaetus eagles, the Javan Hawk-Eagle was not recognised as a full species until 1953.

It is one of the rarest raptors. Due to ongoing habitat loss, small population size, limited range and hunting in some areas, it is evaluated as Endangered on the IUCN Red List of Threatened Species. It is listed on Appendix II of CITES.

In May 2011, there were only around 400 Javan Hawk-Eagles living in the wild.[3]
