Population justification: The global population size has not been quantified, but the species is described as common to abundant in Central Asia and local in Arabia (del Hoyo et al. 2006). The European population is estimated at 1,000-10,000 pairs, which equates to 2,000-20,000 mature individuals (BirdLife International 2015). However 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 small European population is estimated to be increasing (BirdLife International 2015).
