  • S8486 - Estimated by Scott (2002) as 25,000-1,000,000. However, count totals in the ppotential wintering range never exceeded 10,000 individuals and after accounting for missing counts from the network of sites 20,000 individuals (Wetlands International, unpublished IWC data). The new estimate takes into account the low coverage of the wintering range.
