Population justification: In Europe, the breeding population is estimated to number c.1,480,000-2,920,000 pairs, which equates to 2,950,000-5,830,000 mature individuals (BirdLife International 2015). Europe forms approximately 30% of the global range, so a very preliminary estimate of the global population size is c. 9,800,000-19,400,000 mature individuals although further validation of this estimate is needed. The population is therefore placed in the band 9,000,000-19,999,999 mature individuals. 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). Local extinctions have been recorded in parts of China and Mongolia as a result of forest loss (Madge and McGowan 2002). Within the species's European range the population is estimated to be stable (BirdLife International 2015, EBCC 2015).
