Population justification: The global population size has not been quantified, but the species is reported to be relatively common on Grande Comore and rare on Anjouan (Louette 2008, K. Green in litt. 2014, M. Louette in litt. 2014, G. Rocamora in litt. 2014). During intensive point count surveys on Anjouan in 2010-2011, only 81 records of this species were obtained in 13 sites (K. Green in litt. 2014). 
It is suspected that the population numbers less than 2,500 mature individuals in total, including over 1,000 mature individuals in the population on Grande Comore. It is therefore placed in the band of 1,000-2,499 mature individuals, which is assumed to equate to c.1,500-3,800 individuals in total.

Trend justification: The population is suspected to be in slow decline owing to on-going habitat loss. Tree cover loss within the range is currently estimated at approximately 6% across the past three generations (16 years; Global Forest Watch 2023, using Hansen et al. [2013] data and methods disclosed therein), likely accelerating to 7% between 2013 and 2028, and considering this habitat loss is ongoing, it is also suspected to continue at a similar, albeit slightly lower, rate over the next three generations, based on the average annual rate of decline of the past five years. However, the species does also occur in agroforests and other degraded woodlands (G. Rocamora in litt. 2014), so forest loss alone is unlikely to drive any major declines. Population declines are overall therefore suspected to not exceed 10% over three generations.
