Notes

  • S2723 - Dodman (2002) presents details of an estimate totalling 13,500,000 in the W Indian Ocean islands and E African coast alone. For populations over 2 million birds, Ramsar Convention criterion 5 (20,000 or more waterbirds) applies.
  • S2724 - Close to 3,000,000 pairs in Seychelles, and large colonies also at several other sites.
  • S8250 - The overall estimate for this population is 18,223,468 - 18,227,968 individuals.
  • T6250 - New data inadequate to revise trend. There has been no recent overview of the subspecies in the western Indian Ocean since Feare et al. who estimated some populations to be increasing while others decreased, in numbers, but most trends remain unknown.
  • T7954 - No information available for a new assessment. There has been no recent overview of the subspecies in the western Indian Ocean since Feare et al. who estimated some populations to be increasing while others decreased, in numbers, but most trends remain unknown.
