  • S7856 - Trolliet, B. In litt 2011. Considers former estimate unlikely.
  • S4189 - 920. Considers old estimate unlikely.
  • S8611 - Recent analysis that discounts the extremely high estimate of Range Ecology Survey (1983) from the Sudd.
  • T6604 - Hockey et al. (2005). Has been steadily increasing in Southern Africa for decades; in need of up-to-date confirmation however.
