Notes

  • T5904 - BirdLife International 2004b: Decrease in all countries except Ukraine between 1990 and 2000.
  • T3139 - 898. Trend 1986-2007: +10.3% p.a. – Increase. 64: Decrease in all countries except Ukraine between 1990 and 2000.
  • S8520 - BirdLife International (2004) reported 14,425-23,385 pairs from AL, BG, GR, RO, RU (50%), TR and UA, ie. 43,000-70,000 individuals only in the European part of the range. This is a much higher number than estimated by Monval & Pirot (1989). However, count totals in TR show substantial increase since the early 1990s with count totals reaching 10,849 individuals in 2011 and 20,289 individuals in 2012 and 16,899 individuals in 2013.
  • S8892 - 13,470 - 20,523 pairs in AL, AM, BG, GE, GR, MD, RO, RU, TR, UA
  • T6903 - The trend assessment is based on the IWC trend analysis (Wetlands International 2017), which shows a strong increase from 1990 well supported also by the count totals. This agrees with the assessment by BirdLife International (2015). However, wintering data contradicts the small decline they reported both for the short- and the long-term trend, which based mainly on the assessment for TR which was reported as a poor trend estimate by the country itself.
