Notes

  • S2335 - BirdLife International (2005) gives estimate of 12,000 individuals (<10,000 mature adults).
  • S7271 - BirdLife International (2005) gives estimate of 12,000 individuals (<10,000 mature adults).
  • T7715 - No information available for a new assessment; previous estimate from 2006 (Wetlands International, 2006). The species breeds in remote lakes across Central Asia and are not properly censused. Water level changes over time result in shrinkage and loss of breeding islands. On long term study at Hongjian Lake, a major breeding site in CN indicated the population increased from 174 in 2001 to the maximum value of 15,494 in 2010, and the population decreased from 15,412 in 2011 to 4,000 in 2015 (Liang & Yan 2017). Breeding numbers have declined in the last years at Ordos, another major site, due to lake shrinkage (Yan et al. 2017).
