Population justification: An estimate of 7,000-12,500 mature individuals was extrapolated from a number of regional estimates. This equates to 10,500-18,750 individuals in total, here rounded to 10,000-20,000 individuals.
Trend justification: The species has shown severe declines throughout its West African range (F. Dowsett-Lemaire in litt. 2006; J.M. Thiollay in litt. 2006) and also across southern Africa (Ferguson-Lees et al. 2001), thus its global population is estimated to be declining at a slow to moderate rate.
