Population justification: In Kenya, Arabuko-Sokoke Forest has been estimated to support c.13,000 individuals, but this number has now decreased and possibly only c. 5,500 individuals are present in Brachystegia woodland (Otieno et al. 2014). There are no estimates for Tanzanian populations, but the sites where the bird occurs are small, and most are very heavily degraded (N. Burgess in litt. 2007). The total population is therefore placed in the range band for 2,500-9,999 individuals. This equates to 1,667-3,333 mature individuals, rounded here to 1,600-3,400 mature individuals.

Trend justification: The population is suspected to be in decline owing to the clearance and degradation of the species's forest habitat, mainly through charcoal burning, agricultural encroachment, logging and pole cutting. The likely rate of decline has not been estimated.
