Population justification: The population is estimated to number 107,000 individuals, roughly equating to 71,000 mature individuals. Numbers are suspected to fluctuate, but with a stable trend over the longer term (Wetlands International 2023).
Trend justification: The population is suspected to be fluctuating owing to fluctuations in the amount of suitable breeding habitat (del Hoyo et al. 1996).
