Javan Hawk Eagle (Nisaetus bartelsi) lives in tropical rainforest across Southeast Asia. It feeds on small mammals birds. Its conservation status is Endangered.
Fascinating facts about the Javan Hawk Eagle
- The Javan hawk-eagle is Indonesia's national bird and serves as the living model for the Garuda Pancasila emblem, which draws on the Garuda deity of Hindu and Buddhist tradition. It is a medium-sized, dark brown raptor that belongs to the Accipitridae family. Endemic to Java, it inhabits the island's humid tropical forests, linking the nation's cultural symbol to its native wildlife.
- In February 2012 only about 325 pairs of Javan hawk-eagles were counted in the wild, centred on Malangbong in West Java with a few additional pairs in East Java. As an Indonesian endemic, the species lives in the humid tropical forests of Java, often within protected areas such as Bromo Tengger Semeru and Meru Betiri National Parks. The bird is believed to be monogamous, with the female typically laying a single egg high in a forest-tree nest.
- Conservation models show the eagle needs roughly 1,450 breeding pairs to maintain a viable population, yet it is one of the rarest raptors and is listed as Endangered on the IUCN Red List because of habitat loss, a tiny population, limited range and hunting pressure. Without protective action, the species was forecast to become extinct by 2025. These figures highlight the urgent need for habitat preservation and anti-poaching measures.
- The Javan hawk-eagle sports a distinctive long black crest that rises almost vertically from its head, ending in a white tip that creates a striking visual contrast. This crest is a key part of its striking plumage, which also includes a rufous head and neck and heavily barred black underparts. Adults measure about 60 cm in length, giving the bird a compact yet powerful silhouette.
- As a medium-sized, dark brown raptor, the Javan hawk-eagle relies on a varied diet centred on other birds and lizards, but it also captures fruit bats and a range of small mammals. This prey selection reflects its hunting skill in the humid tropical forests of Java, where it perches high before swooping on unsuspecting victims. The diet's emphasis on vertebrate prey supports the eagle's energetic needs for breeding and territorial defence.

About the Javan Hawk Eagle
In the mist-shrouded forests of Java, the Javan Hawk Eagle soars with majestic precision, its broad wings beating powerful and slow as it scans the treetops for unsuspecting prey. With eyes as sharp as the crests of the volcanic peaks that pierce the island's sky, this regal raptor navigates the dense canopy with ease, its tawny feathers glistening like burnished gold in the dappled light. As it rides the thermals high above the forest floor, the Javan Hawk Eagle embodies a fierce and unyielding spirit, a true monarch of the dwindling wilds.
