More valuable than ivory

That's the helmeted hornbill. It goes for about $6,150 per kilogram - three times more than elephant ivory. Part of its head (its helmet) has been used for centuries by Chinese and Japanese craftsmen to create artifacts for the rich and powerful. Many were bought by the Victorians as part of their netsuke collection.

Thousands of these birds are killed each year. Plus, their habitat in Asia's rainforests is being destroyed; researchers estimate that the habitat is shrinking 3% a year. The birds are now considered Near Threatened.
