Population justification: Otieno et al. (2007) estimated the population density of the Kereita forest block in the Kikuyu escarpment forest, Kenya, to be 1 bird/3 km2. This species is described as locally scarce (Zimmerman et al. 1996) to locally common (Bennun and Njoroge 1999). The area of mapped range is 3,909 km2 (BirdLife International 2021). Assuming that it inhabits the range at the same population densities observed by Otieno et al. (2007), then the total population may be estimated at 1,303 individuals. This is roughly equivalent to 873 mature individuals, hence it is placed here in the band 250-999 mature individuals.

This species has a small range. There is some evidence to suggest that this species may make substantial movements between the different forest blocks in which it occurs (Zimmerman et al. 1996; J. Bradley in litt. 2021). Therefore, in the absence of other data, it is assumed that the species functions as one subpopulation.

Trend justification: The species's population is inferred to be declining in line with the clearance and degradation of highland forest within its range (Otieno et al. 2007; Global Forest Watch 2020), and reports of a reduction of observation records at monitored sites (P. Gacheru in litt. 2021). The likely rate of decline is tentatively suspected to fall in the band of 1-10% over three generations.
