The Volcano Swiftlet is an Indonesian endemic, named for its affinity for volcanic environments. It is a sleek, dark swiftlet that spends its days gracefully maneuvering through the air in pursuit of insects.
Where to spot
Endemic to the island of Java, Indonesia, particularly found near volcanic mountains and their associated caves or fumaroles. They forage over montane forests and open areas.
How to spot
Look for rapid-flying, dark swiftlets in the vicinity of volcanic peaks. Their association with such specific habitats can be a key identification clue. Observing them near cave entrances or high cliffs is ideal.
When to spot
Can be observed year-round during daylight hours. They are most active during the cooler parts of the day, such as morning and late afternoon.
This swiftlet is known to nest and roost in the sulfurous, often dark, environments within volcanic craters or lava tubes, utilizing its echolocation for navigation.
