Population justification: The global population size has not been quantified. In Europe, the breeding population is estimated to number 1,000-5,000 breeding pairs, equating to 3,000-15,000 individuals (BirdLife International 2004), but Europe forms <5% of the global range.

Trend justification: The population is suspected to be stable in the absence of evidence for any current declines or substantial threats.
