Javan Hawk-Eagle

It faces a very high risk of extinction in the wild in the near future. See full glossary
The Javan hawk-eagle is a raptor endemic to the island, with a very long upright crest and a finely streaked breast. It is the national bird of Indonesia and was chosen as the symbol of Garuda, the mythical mount of Vishnu. Its habitat, the montane forest of Java, has been reduced to fragments on one of the most densely populated islands on the planet, and a few hundred birds remain, scattered among volcanoes and national parks.
