Notes

  • S553 - Population size probably close to 1 million (Jaensch 2005).
  • S6290 - Estimate based on national survey at end of major drought as well as consideration of high counts from key sites during wetter periods.
  • T4736 - Numbers fluctuate naturally but trend is possibly decreasing due to reduced availability of some important breeding habitat due to river regulation; dives to feed so does use artificial habitats such as reservoirs.
