Justification of Red List category
This spectacular hornbill has been uplisted from Near Threatened to Critically Endangered owing to severe hunting pressure for its casque and as a result of habitat loss from logging and agricultural conversion. Hunting pressure is expected to increase and spread across the species's range given the value that is placed on the species's 'ivory' casque in illegal trade.
