Population justification: In Europe, the breeding population is estimated to number 30,500,000-44,200,000 pairs, which equates to 61,100,000-88,400,000 mature individuals (BirdLife International 2015). Europe forms c.35% of the global range, so a very preliminary estimate of the global population size is 174,600,000-252,600,000 mature 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 Japan and c.10,000-100,000 breeding pairs in Russia and (for the subspecies songara) c.100-10,000 breeding pairs in China (Brazil 2009).

Trend justification: Both increases and decreases in regional populations have been noted in the second half of the 20th century (del Hoyo et al. 2007), but in Europe, trends since 1980 show that populations have undergone a moderate decline (EBCC 2015).
