Population justification: The global population size has not been quantified, but the species is still recorded relatively commonly and appears to have a large overall population. The subspecies macgillivrayi is believed to have a stable population of c.3,000 individuals.

Trend justification: The population is suspected to be in decline owing to ongoing habitat destruction and unsustainable levels of exploitation.
