Spotted
The Helmeted Hornbill is a massive, critically endangered hornbill of Southeast Asian rainforests, distinguished by its unique solid casque, which extends from its bill to its forehead, and its long central tail feathers. Its plumage is primarily dark brown with a white belly and tail.
Where to spot
Found in the Malay Peninsula, Sumatra, Borneo, and parts of Thailand and Myanmar. Inhabits primary lowland evergreen forests.
How to spot
Look for its massive size, the unique solid casque, and very long central tail feathers. Listen for its remarkable, loud, resonant calls, which start as slow hoots and accelerate into a laughing chorus, often called 'laughing hornbill'.
When to spot
Resident year-round, but highly elusive due to poaching pressure. Active during the day, often heard more than seen, especially at dawn and dusk.

Unlike other hornbills whose casques are hollow, the Helmeted Hornbill's casque is solid keratin, making up about 10% of its body weight. This 'hornbill ivory' is highly prized for carving, leading to severe poaching.
