Notes

  • S2723 - 192 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 population estimate for this species is of 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. [13] who estimated some populations to be increasing while others decreased, in numbers, but most trends remain unknown.
