Justification of Red List category
This hornbill faces the possibility of imminent extinction. It has a tiny population probably now confined to just one island. It is likely to be declining very rapidly owing to the continuing loss and degradation of the few remaining forest tracts in its range, and levels of exploitation. For these reasons, it is listed as Critically Endangered.
