Population justification: In Europe, the breeding population is estimated to number 460,000-1,000,000 breeding pairs, equating to 1,380,000-3,000,000 individuals (BirdLife International 2004). Europe forms 50-74% of the global range, so a very preliminary estimate of the global population size is 1,860,000-6,000,000 individuals, although further validation of this estimate is needed.
Trend justification: Marked annual fluctuations have been noted within this species's European breeding range (del Hoyo et al. 2006). In Europe, trends since 1996 are uncertain, 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).
