Notes

  • S8437 - Little information on population size is actually available. Del Hoyo (1996) mentions an estimate of c. 40,000 breeding pairs atthe Caspian Sea alone. Jennings (2010) mentions a count of 45,000 at Bar al-Hikman in 1991. There is insufficient information available to improve on the estimate although the current estimate for European RU is only 15,000-20,000 (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.) and IWC count totals only go up to 13 thousands since then.
