Population justification: Gottshalck and Pomeroy (2010) estimated a minimum of 36-45 males in Bwindi Impenetrable National Park. Assuming that only a proportion of its mapped range is occupied by the species, the overall population size is likely to be small and is placed here in the range 2,500-9,999 mature individuals. It is tentatively assessed that the largest subpopulation contains >1,000 mature individuals. However, further study could reveal smaller population sizes.

Trend justification: The population is considered to be in decline owing to ongoing habitat destruction and fragmentation (del Hoyo et al. 2005).
