Population justification: The species is described as not common (Clement et al. 1999), but the global population size has not been quantified directly. Based on density estimates from Turkmenistan (4-7 individuals/km² in the Repetek Reserve and 0.4 individuals/km² in central Kara Kun; Atamuradov 1999) and assuming that only 10% of the Extent of Occurrence are occupied, the global population may number 7,000-125,000 mature individuals.

Trend justification: The species is assumed to be undergoing a decline and range contraction (del Hoyo et al. 2019), but the reasons for the decline are unclear. It is now extinct in Iran.
