Notes

  • S3764 - 289: Large numbers [130,000] estimated southern New Guinea but not known if migrants from Australia.
  • T2345 - 344: Trend in Australia declining.
  • S7653 - Numbers clearly between 100,000 and 1,000,000 either in Australia or S New Guinea; probable migration precludes summation. Additional birds in Indonesia (no information) or failure to confirm migration would raise possibility of estimate in excess of 1,000,000.
  • T5584 - In Australia, northern colonies secure but overall likely declining trend due to loss of southernmost colonies due to river regulation for irrigation.
