Notes

  • S3124 - 64: Breeding population in relevant countries 193,322-290,850 pairs (579,960-872,550 individuals).
  • T1909 - 914. Increasing in W Mediterranean, decreasing in E Mediterranean/Black Sea.
  • S8457 - 18,900-35,800 pairs in SK, HU, RO and BG (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.). Further 113,422-176,950 pairs in RU (90%) , BY, UA, MD, GE, AM, GR, MK, AL, RS&ME, BA and HR (BirdLife International, 2004). This yields a population estimate of 397,000-638,000 individuals after rounding. Difference in estimate is caused by allocating FI, EE, LT, LV and PL to the NW & W European wintering population following the delineation on the Critical Site Network Tool.
  • T6455 - Decreased only in HR and TR, increased in BY and UA, stable or unknown in the rest of the breeding range (BirdLife International, 2004). Stable in SK, BG and SI, unknown in HU and RO (European Topic Centre on Biological Diversity, in prep.).
  • S8828 - 156,645-238,670 pairs in AL, AM, BA, BG, BY, GE, GR, HR, HU, MD, ME, MK, RO, RS, RU, SI, SK, TR, UA and XK (BirdLife International 2015).
  • T6784 - The breeding population appears to be stable in all range states except MD in the short-term. In the long-term, trends are often unknow. Decline was reported from TR, increase from BY (BirdLife International 2015). The IWC trend analyses indicate continued increase both in the long- and the short-term although the latter is statistically not significant (Wetlands International 2017).
