Population justification: The global population size has not been quantified. In Europe, the breeding population is estimated to number 5,000-20,000 pairs, which equates to 10,000-40,000 mature individuals (BirdLife International 2015), but Europe forms <5% of the global range.

Trend justification: The population is suspected to be stable in the absence of evidence for any declines or substantial threats. The European population trend is unknown (BirdLife International 2015).
