Notes

  • S2861 - 656: <25,000 counted in aerial surveys of Sahel zone from Atlantic to Chad Basin in Jan 2000.
  • S7476 - Trolliet, B. In litt. 2011.. Only 4,131 counted in near-simultaneous aerial counts of W African Sahel, Jan 2006 and concluded that the population has declined.
  • S2863 - 920. Only 4,131 counted in near-simultaneous aerial counts of W African Sahel, Jan 2006 and concluded that the population has declined.
  • S8676 - The population estimate was reduced based on Trolliet, B. In litt. (2011), but over 10,000 in Senegal Delta area in Jan 2014, and 31,694 in northern Nigeria (31,605 at Gashua/Gwayo) in July 2007, whilst there were also 3,920 at Lac Oursi, Burkina Faso in January 2007.
  • T6657 - Trolliet et al. (2008) found only 9,000 individuals on the main Sahelian wetlands in 2007. However, Dodman (2014) notes that over 30,000 were counted in Nigeria and c. 4,000 in Burkina Faso in the same year.
  • T6866 - The long-term trend suggests a statistically significant steep decline. This is mainly driven by the national trends of SN and TD and considered not being representative for the region.
