Population justification: In Europe, the breeding population is estimated to number 480,000-1,000,000 breeding pairs, equating to 1,440,000-3,000,000 individuals (BirdLife International 2004). Europe forms 50-74% of the global range, so a very preliminary estimate of the global population size is 2,000,000-6,000,000 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.
