Population justification: The species is described as scarce, but still widespread (Keith 1997). The population is estimated to number more than 1,000 mature individuals, though possibly not many more (H. Temple in litt. 2005). It is placed in the band 1,000-2,499 mature individuals, equating to 1,500-3,749 individuals in total, rounded here to 1,500-4,000 individuals.
Trend justification: The species has reportedly become less numerous and more local since 1935 (Keith 1997, Raffaele et al. 1998). During a comprehensive survey in 2009, the species had only been recorded in low numbers at few sites (Toussaint 2009). In recent years, evidence for declines has become prevalent as the species appears to be increasingly difficult to record (Aley 2018, J. Mortensen and A. Toussaint per G. Young in litt. 2020). From the declining number of observational records, it is tentatively inferred that the population is in continuing decline. The rate of decline has not been quantified. Given its small population size and the fact that the species is still observed, it is likely that declines are slow to moderate, rather than steep.
