Population justification: The species is known to occur in three areas. Its population in the Brachystegia woodland of Arabuko-Sokoke Forest, Kenya, has been estimated at 2,818 individuals (95% CI: 1,739-4,565) in an area of 77 km2. The remaining occupied range in the East Usambara and Udzungwa Mountains, Tanzania, totals 420 km2, with the population in the Udzungwa Mountains probably numbering 'some hundred' individuals. Its population is therefore suspected to fall within the band 2,500-9,999 individuals. This equates to 1,667-6,666 mature individuals, rounded here to 1,500-7,000 mature individuals.
Trend justification: The comparison of transect survey data from the 1970s and 1999 suggests that the species has declined in Arabuko-Sokoke Forest, Kenya, over this period, despite differences in the survey methods (Davis 2005). This decline is suspected to be continuing, owing to the ongoing degradation of woodland in this area. The species is suspected to be declining in Tanzania, in line with the loss and degradation of forest. The likely overall rate of decline has not been estimated.
