Population justification: In Europe, the breeding population is estimated to number 76,100-124,000 pairs, which equates to 152,000-249,000 mature individuals (BirdLife International 2015). Europe forms c.35% of the global range, so a very preliminary estimate of the global population size is 434,000-712,000 mature 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). The European population trend is unknown (BirdLife International 2015); however, there may have been at least localised declines in some areas (P. Villányi in litt. 2018
