Justification of Red List category
This species, the largest-plumed member of its family, is listed as Vulnerable based on an estimated small population which is believed to be declining owing to hunting. The overall rate of decline is unknown but is extrapolated from historic and recent data from the few study sites. However, it may be secure in the large areas of its range which are inaccessible and largely uninhabited. Should this species be found to be stable, or increasing, it would qualify for downlisting to a lower category of threat.
