Notes

  • T6090 - Wetlands International 2012. Trend 1988-2006: +1.9% p.a. ? Uncertain.
  • T3587 - 898. Trend 1988-2006: +1.9% p.a. – Uncertain.
  • S8544 - 478-2,436 pairs in RO and CY (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.). Further 6,963-13,036 pairs in HR, GR, MK, RU (25%), RS&ME, UA and TR (BirdLife International, 2004). This yields an estimate of 22,000-46,000 individuals (Wetlands International, 2014), which is close to the current estimate. However, recent peak count of 54,046 individuals in 2007 suggests that a higher upper limit might be more appropriate.
  • T6538 - IWC trend analysis results suggest large increase (2003-2012: 1.1002±SE 0.0436). However, this might be driven by the unusually high counts in 2007 and 2011 and might be caused by cold weather movements from neighbouring populations.
  • T6948 - 1992-2015: 1.1012 (SE 0.0313), but indication of decline between the end of the 1960s and 1980s (Wetlands International 2017). Short-term trends in breeding numbers mostly unknown. Long-term trend is reported as negative in TR, RO and UA (BirdLife International 2015), but it is difficult to explain in the light of the much better documented increases in wintering numbers.
