Population justification: In Europe, the breeding population is estimated to number 32,700,000-56,500,000 pairs, which equates to 65,300,000-113,000,000 mature individuals (BirdLife International 2015). 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). It is likely that the global population is within the range 10,000,000-500,000,000 mature individuals.

Trend justification: In Europe the overall trend from 1980-2013 was increasing (EBCC 2015).
