Population justification: In Europe (which covers c.85% of the breeding range), the breeding population is estimated to be 629,000-1,454,000 breeding pairs, based on 491,500-875,000 pairs in Spain, a new estimate of 25,000-50,000 pairs in France (Issa and Muller 2015), 100,000-500,000 pairs in Portugal, 10,000-30,000 pairs in Italy, c.20-30 pairs in Andorra and 2,900-3,600 pairs in the United Kingdom (BirdLife International 2015). This equates to approximately 1,255,000-2,910,000 mature individuals and 1,880,000-4,365,000 individuals.
Trend justification: Data from the Spanish common bird monitoring scheme (SACRE) suggest that the species may have declined by an average of 4.6% (95% CI: 6.2-3.1) per year during 1998-2011 (V. Escandell in litt. 2012), with declines occurring in all regions (and hence not simply attributable to a northwards shift in the species's range, as predicted under climate change scenarios). The European Red List of Birds estimated the population to be decreasing at a rate approaching 30% in 12.3 years or three generations (BirdLife International 2015). The population trend for the species produced by the Pan-European Common Bird Monitoring Scheme suggests that it declined by 32% over the period 1980-2012 and by 24% over the period 2003-2012 (EBCC 2016). Whilst populations in Portugal and the United Kingdom are increasing, declines have been reported for both France and Italy. The overall population trend is estimated to be decreasing at a rate of 20-29% over three generations.
