Population justification: Combined totals from across the whole range estimate the number of pairs at 31,372 (26,014-36,731), which equates to 62,744 (52,028-73,462) mature individuals or 94,116 (78,042-110,193) individuals (I. Karyakin in litt. 2015). The global population is hence below 37,000 pairs (Karyakin et al. 2016).

Trend justification: The population is declining owing to habitat destruction (especially conversion of steppe into agricultural land), persecution, and collisions with power lines. Locally populations are declining owing to heavy predation of chicks (Ferguson-Lees and Christie 2001). In Europe the population size is estimated to be decreasing by 80% or more in 42.06 years (three generations [Bird et al. 2020]) (BirdLife International in prep.) however the European population represents only a small proportion of the global population. Combined totals from across the species's range suggest a decline of 58.6% between 1997-2011 and 2013-2015 (I. Karyakin in litt. 2015), however counts of birds passing through the migration bottleneck of Eilat, Israel have not recorded a significant decline in a comparison of data from 1977-1988 and 2015-2018, although the mean number of birds counted had reduced (19,540 to 15,192) (Weiss et al. 2019). Overall, the rate of population reduction is suspected to be very rapid, exceeding 50% over the past and current three-generation periods, and in the absence of evidence that the threats impacting the species have been adequately addressed this reduction is suspected to continue at this rate over the next three generations.
