Hornbills are iconic birds of tropical forests threatened by habitat loss and — for helmeted hornbills — a brutal trade in their solid casques carved as "red ivory," driving a conservation and welfare crisis.
Helmeted hornbills killed for their casques are typically shot — their solid casques, unlike hollow horn, make them easy targets because they are heavy-headed and slow. Birds killed for their casques die through shooting, with welfare outcomes depending on kill shot accuracy. The rapid population decline from this trade means individual welfare harms aggregate to a conservation emergency. Other hornbill species losing habitat through deforestation face progressive restriction of their forest territory — large birds with large home range requirements cannot persist in forest fragments inadequate for their foraging and nesting needs. The captive breeding challenges that limit ex-situ conservation mean that in-situ habitat protection is the primary welfare and conservation intervention for hornbills.
