Notes

  • S3350 - Estimate includes Australian element of territori.
  • S6357 - Substantial occurrence in S New Guinea, possibly involves breeding and migrant populations. Data remain inadequate for developing a numerical estimate.
  • T5273 - Size of population fluctuates more widely than indicated by previous assessment.
