Population justification: The global population is estimated to number c.315,000 individuals (Wetlands International 2015) of which c. 270,000 reach Australia during the non-breeding season.
Trend justification: The overall population trend is thought to be declining, based on monitoring data from Australia and New Zealand which reported a population decline of 29% over three generations (Studds et al. in prep). Further research is needed to ascertain whether this is entirely due to a genuine global decline or whether it can partly be accounted for by a shift in the wintering range.
