Notes

  • S8481 - Jennings 2010. 69 pairs in Yemen. Aerial survey in Febr 1993 found 422 birds along the Red Sea coast between Jizan and Gulf of Aquaba.
  • S8912 - See CSR6 and Sheldon (2017).
  • T6837 - Dodman (2014) assumed that the population is stable in the absence of human impacts along the Red Sea coast. Reviewing of available IWC data and the formal trend analysis suggest that a steep decline might have taken place between 1990 and 2015 (Wetlands International 2017). This is probably driven by destruction of coastal wetlands and mangroves particularly along the northern coast of the Red Sea (Nagy et al. 2014).
