Sumatran Frogmouth: Night Guardian of the Sumatran Forest

The forests of Sumatra, renowned for their biodiversity, are home to a number of unique species, including the mysterious nocturnal bird, the Sumatran Frogmouth (Batrachostomus poliolophus). This bird is one of Sumatra’s rarely seen endemics, making it a hidden icon that captivates birdwatchers and researchers.

The Sumatran Frogmouth has a distinctive appearance, with patterned brown feathers, making it difficult to distinguish from the dry twigs and leaves on which it rests. This species measures around 20-23 cm, and has a wide, frog-like beak that gives it its name. This bird is active at night (nocturnal) and is often found in the highland forests of Sumatra.

This bird prefers intact primary forest, but is also found in fairly dense secondary forest. It hunts small insects and other prey by lying in wait, relying on its camouflage to ambush its prey. During the day, the Sumatran Frogmouth usually rests on low branches, often undetected except by keen observers.

As a rare and little-studied species, the Sumatran Frogmouth is an indicator of forest health. Its presence reflects the good quality of the forest ecosystem and still supports the life of very specific species such as birds

For birdwatchers visiting Sumatra, finding the Sumatran Frogmouth is an unforgettable experience. With an experienced local guide, such as from Letsbirding Sumatra, Birding Tour for Conservation, you can explore the forests of Leuser or other areas to try your luck.
