Population justification: In Europe, the breeding population is estimated to number 1,900,000-4,600,000 breeding pairs, equating to 5,700,000-13,800,000 individuals (BirdLife International 2004). Europe forms 75-94% of the global range, so a very preliminary estimate of the global population size is 6,060,000-18,400,000 individuals, although further validation of this estimate is needed.
Trend justification: The population is suspected to be stable in the absence of evidence for any declines or substantial threats. In Europe, trends since 1982 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).
