Notes

  • S8429 - Estimate is based on Perennou et al. (1994) and there is insufficient information to improve on the estimate. On average, 1,600 individuals were counted on mid-winter counts in IR between 2004 and 2007. Average count total in SA was 664 individuals between 1992 and 1995, but only 143 along the Gulf and 218 along the 7% of the Red Sea coast was counted in Jan. 2014 (Nagy et al., in prep.). 558 at Bar al Hikman in Dec. 2013 (De Fouw in litt, 2014). Little information is available about breeding numbers. The entire population for European RU is 2,000-5,000 pairs, but that partly breeds along the Black Sea (BirdLife International, 2004). It is a common breeder in KZ (Gavrilov & Gavrilov, 2005). No more than 1,000 pairs in Arabia (Jennings 2010).
