Population justification: In Europe, the breeding population is estimated to number c.2,500,000-3,100,000 breeding pairs, equating to c.7,500,000-9,300,000 individuals (BirdLife International 2004). Europe forms 25-49% of the global range, so a very preliminary estimate of the global population size is c.15,000,000-40,000,000 individuals, although further validation of this estimate is needed. In addition, national population estimates include: c.10,000-100,000 breeding pairs in China; c.100-10,000 breeding pairs in Korea; c.100-10,000 breeding pairs in Japan and c.100,000-1 million breeding pairs in Russia (Brazil 2009).
Trend justification: The population is suspected to be declining owing to habitat destruction (del Hoyo et al. 1994). In Europe, trends since 1980 show that populations have undergone a moderate decline (p<0.01), based on provisional data for 21 countries from the Pan-European Common Bird Monitoring Scheme (EBCC/RSPB/BirdLife/Statistics Netherlands; P. Vorisek in litt. 2008).
