Notes

  • S5208 - 344 gives estimate of 100,000 - 1,000,000, for Australia, and suggests that real total is 400,000-800,000. "Local in New Guinea" (181), indicating that overall population probably below 1,000,000.
  • S8008 - Estimated population size in Australia derived from the 2008 National Survey of Waterbirds, which confirms previous estimate, and evidence from subsequent post-drought recovery.
  • T6015 - Trend not clear and species is well adapted to urban and farm areas but habitat loss due to inland river regulation and coastal development possibly has inflicted some long-term decline.
