Notes

  • S8335 - Only 107 counted at Bar al Hikman in Dec. 2013 (de Fouw, in litt) and they estimated a maximum of 1000. Recent maximum was 488 individuals in IR. 10 individuals in UAE Jan. 2013. None observed at the Tarut Bay and surrounding areas in Jan. 2014 (Nagy et al., in prep.).
  • T6335 - Decreasing counts from IR and OM (van Roomen & Amini, 2009, de Fouw, in litt.).
  • T7195 - The result of the IWC trend analysis is uncertain but count totals suggest a decreasing tendency. This is consistent with the references mentioned in CSR6.
