Notes

  • S4311 - There were ca. 3,000 individuals in the 1930s, 1,500 in 1940 and 250-380 in the early 1980s (627). Based on a survey in 1999, 69 estimates 220 and INC, whilst 65 gives 227 and DEC. In 1999, there were 85 breeding pairs (321).
  • S8610 - 350 (Franchimont et al. 2010); 443 post breeding in 2013. 113 breeding pairs laid eggs in 2013 (C. Bowden, in litt. 2014 based on information from Souss-Massa National Park, Oubrou & El Bekkay, 2014). A range is given to cater for inter-annual fluctuations and allow for potential winter mortality since 2013 post breeding figure.
  • T6500 - Major past declines, but trend in last 5-10 years has been overall increasing (eg 227 in WPE5) despite some fluctuations.
