Ijen is not just about the beautiful crater-lake; it is surrounded by a lush belt of forest, which is a great place to observe flora and fauna. If you are lucky, you could spot some of the rare endemic birds of Java, such as the majestic Javan Hawk Eagle, which can be found nowhere else in the world. Catching a glimpse of this rare and endangered bird of prey is something special, as it is now rarely seen due to habitat loss. The Javan Hawk Eagle can be seen soaring low, just over the forest canopy where it hunts for its prey. Another spectacular bird is the Yellow-throated Hanging Parrot; this is the only parrot to be found in Java, and quite rare at that. Look for it high in the trees, possibly feeding on fruiting fig trees or other flowering trees. Flowering and fruiting trees are the best place to stop and wait; this is nature’s buffet for birds and other animals.
