Notes

  • S3373 - 64: 36,250-42,350 pairs (108,750-127,050 individuals). Mostly 1996-2002.
  • T5283 - Wetlands International 2012. Trend: +4.8% for 1988-2007 ? Increase.
  • T2071 - 898. Trend: +4.8% for 1988-2007 – Increase.
  • T6466 - Bregnballe et al. (2014) reported a decline of 23% decline between two surveys in 2006 and 2012. European Topic Centre on Biological Diversity (in prep.) and BirdLife International et al. (in prep.) data suggests stable population trend during 2000-2012 (-0.16 - +0.13 p.a.) and a moderately increasing (+0.42-056% p.a.) one over 1980-2012.
  • S8836 - BirdLife International estimated the population size to be 33,973-34,386 pairs (i.e. 102,000-103,000 individuals) but this includes also outdated data from the UK. Therefore data from the most recent specialised census was retained (Begnballe et al. 2014).
  • T6800 - Bregnballe et al. (2014) reported 23% decline between two surveys in 2006 and 2012. This agrees with the short-term trend reported by BirdLife International (2015). However, the population has increased in the long-term (BirdLife International, 2015).
