Population justification: Rich et al. (2004) estimated the global population to number 40,000,000 individuals. In Europe, the breeding population is estimated to number 23,000,000-40,000,000 breeding pairs, equating to 69,000,000-120,000,000 individuals (BirdLife International 2004). Europe forms 5-24% of the global range, so a very preliminary estimate of the global population size is 288,000,000-2,400,000,000 individuals, although further validation of this estimate is needed. National population estimates include: c.10,000-100,000 breeding pairs in China; c.100-100,000 breeding pairs in Taiwan; possibly c.10,000-100,000 breeding pairs in Korea; c.100-100,000 breeding pairs in Japan and possibly c.10,000-100,000 breeding pairs and c.1,000-10,000 individuals on migration in Russia (Brazil 2009).
Trend justification: The population trend is difficult to determine because of uncertainty over the impacts of habitat modification on population sizes. In Europe, trends since 1980 show that populations have undergone a moderate increase (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).
