Population justification: In Europe, the breeding population is estimated to number 150000-300000 breeding pairs, equating to 450000-900000 individuals (BirdLife International 2004). Europe forms 25-49% of the global range, so a very preliminary estimate of the global population size is 918000-3600000 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 (del Hoyo et al. 2006).
