Population justification: Arabuko-Sokoke Forest in Kenya is believed to support c.7,500 pairs or around 15,000 mature individuals. Zanzibar is thought to host 100 pairs (L. Hansen in litt. 2021). Other subpopulations in Tanzania, Malawi and Mozambique are not thought to be large. Hence the global population is best treated as moderately small, at 10,000-19,999 mature individuals. This equates to 15,000-29,999 individuals in total.

Trend justification: The population is inferred to be in decline owing to ongoing habitat destruction. Remote-sensing data suggests that this species's range lost 9.7% of forest cover between 2010-2020 (Global Forest Watch 2021). Between 2017-2020, the range lost 4.2% of forest cover (Global Forest Watch 2021), equivalent to 10.2% when projected forward over 10 years. With the additional habitat degradation and the removal of dead logs and moss (P. Matiku in litt. 2021; J. John in litt. 2021), it is suspected that the species may experience declines in the range of 20-25% over three generations in the future.
