| Population justification: In Europe, the breeding population is estimated to number 260,000-460,000 breeding pairs, equating to 780,000-1,380,000 individuals (BirdLife International 2004). Europe forms 5-24% of the global range, so a very preliminary estimate of the global population size is 3,250,000-27,600,000 individuals, although further validation of this estimate is needed. National population estimates include: c.10,000-100,000 breeding pairs in China; < c.100 introduced breeding pairs in Taiwan; c.10,000-100,000 breeding pairs in Korea; c.100-10,000 breeding pairs in Japan and possibly c.100-10,000 breeding pairs in Russia (Brazil 2009). | ||||
| Trend justification: The population is estimated to be increasing following noted increases in parts of the species's range (Madge and Burn 1993). In Europe, trends since 1996 show that populations have undergone a moderate increase (p<0.05), 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). | ||||
