Notes

  • S8658 - No update to estimate in AEWA SSAP (Tyler 2013)
  • T6638 - The population is suspected to be in decline owing to the effects of habitat conversion and degradation, and human disturbance. The likely rate of decline, however, has not been estimated (BirdLife International, 2014). Based on this, significant long-term decline maintained.
  • T6830 - The population is suspected to be in decline owing to the effects of habitat conversion and degradation, and human disturbance. The likely rate of decline, however, has not been estimated (BirdLife International, 2017). recent IWC trend analysis provides some week support to this assumption (Wetlands International 2017). Significant long-term decline maintained.
