Population [top]
Population: In Europe, the breeding population is estimated to number 400,000-860,000 breeding pairs, equating to 1,200,000-2,580,000 individuals (BirdLife International 2004). Europe forms 25-49% of the global range, so a very preliminary estimate of the global population size is 2,450,000-10,300,000 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; c.100-10,000 breeding pairs in Korea; c.100-10,000 breeding pairs in Japan and c.10,000-100,000 breeding pairs in Russia (Brazil 2009).
Trend Justification: The population is suspected to be in decline, e.g. owing to forest destruction in Taiwan (Madge and Burn 1993). In Europe, trends since 1980 have been stable, 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).
Current Population Trend: Decreasing
Additional data:
? Continuing decline of mature individuals: Unknown
? Extreme fluctuations: No ? Population severely fragmented: No
? Continuing decline in subpopulations: Unknown
? Extreme fluctuations in subpopulations: No ? All individuals in one subpopulation: No
