Helmeted hornbill
Rhinoplax vigil
The strangest of the eight — a hornbill with a solid casque, a maniacal laughing call, and the grim distinction of being hunted for that very casque.
The bird
Field notes
Unlike its relatives' hollow casques, the helmeted hornbill's is solid keratin — "hornbill ivory" — which is exactly why it has been hunted to the edge across its range. In intact forest like Danum it hangs on, and hearing one is unforgettable: a long series of hoots that accelerates into a burst of manic laughter rolling across the valley.
Males fight in mid-air, casque to casque, over the fig trees they prize. Seeing that is a lifetime's luck; hearing the laugh and glimpsing the long tail-streamers over the canopy is reward enough, and Danum is one of the better places left to try.
Seen in Danum
The tallest emergents and fruiting figs, viewed from the canopy walkway and the Study Centre's tower. Listen first — the call carries far.
Best site & season
Resident year-round; fruiting figs pull them in. Fewer and shyer than the commoner hornbills, so budget more mornings.
