Population justification: A survey in 1999-2000 estimated the population at 1,200 pairs or 2,400 mature individuals, and repeat surveys in 2006, 2007 and 2015 found that it had not changed significantly (J. John in litt. 2016). This total roughly equates to 3,600 individuals in total.

Trend justification: Although available habitat is probably declining in extent and quality, repeat surveys have not revealed population declines (J. John in litt. 2007). Habitat has been lost from outside the northern end of the Uluguru Nature Reserve, but restoration in the 100 ha Bunduki gap is being conducted, hence the population may remain stable into the future.
