Notes

  • T5355 - Wetlands International 2012. Trend 1990-2007: +7.9% p.a. ? Increase.
  • T2189 - 898. Trend 1990-2007: +7.9% p.a. – Increase.
  • S8478 - Total of national breeding population estimates from BE, ES, Canary Islands, FR, IE, IT, NL, PT, UK is 34,668-34,472 pairs, i.e. 102,000-103,000 individuals (European Topic Centre on Biological Diversity, in prep.). 1500-3500 resident birds can be also added for NW Africa (Dodman, 2014).
  • T6475 - Based on the breeding numbers, 9-16% decline in the last decade. However, the long-term trend from 1980 to 2012 still represents 81-89% increase (European Topic Centre on Biological Diversity, in prep.).
  • S8850 - 34,668-34,472 pairs in BE, ES, ESIC, FR, IE, IT, NL, PT & UK (BirdLife International 2015). 1500-3500 resident birds can be also added for NW Africa (Dodman, 2014).
  • T6833 - Declines in the short-term but increased in the long one.
  • S9358 - The size of the breeding population is estimated at 31,326-33,997 pairs in BE, ES, ESIC, FR, IE, IT, NL, PT, GB (BirdLife International, in prep.) based on data from the period of 2003-2018. Dodman (2014) estimated another 1,500 – 3500 individuals in NW Africa. This result in an estimate of 95,000-105,000 individuals.
  • T7459 - Based on BirdLife International (in prep.), it is estimated that the breeding population has decreased by 12-15% in BE, FR, IE, IT, NL, GB between 2009 and 2018. No quantitative trend information is available from ES, ESIC, PT and NW Africa. However, the population in ES is thought to be stable. Hence, this short-term trend is not fully representative of the population. It has also increased by 142-142% in BE, ES, ESIC, FR, IE, NL, GB between 1980 and 2018. No quantitative trend information is available from IT, PT and NW Africa. Based on breeding bird data from the Pan-European Common Bird Monitoring Scheme from FR, ES and PT, Nagy et al. (2020) reported moderate decrease for 1998-2017 (0.9819), stable trend for 2005-2017 (1.0037) and uncertain trend for 2008-2017 (1.0221).
