Population justification: Alonso (2014) estimates the global population to number 43,847 – 56,695 individuals, rounded here to 44,000-57,000 individuals.

Trend justification: The species is suspected to have historically undergone a rapid population decline, owing to habitat loss and fragmentation for agricultural intensification, as well as hunting and collision with power lines. There is a lack of accurate data on current trends in several countries with important populations (e.g. parts of Russia, Mongolia, China), although declines have continued in some range states especially in eastern and central Europe, Morocco, as well as throughout the eastern part of the global distribution (Chan and Goroshko 1998, Barati and Amerifar 2008, Palacín and Alonso 2008, Oparin et al. 2013, BirdLife International 2015, Alonso et al. 2016b, M. Karataş in litt. 2016). In other areas (notably Hungary, Germany, Austria and the Iberian Peninsula) the population has been increasing or potentially stable since the 1990s (see Nagy 2009, Martín et al. 2012, BirdLife International 2015, J. Garrido in litt. 2017). Therefore, declines in the recent past are not thought to be significant (see Alonso 2014, Palacín and Alonso 2008, Alonso and Palacín 2010). However, the population in the Iberian Peninsula may now (at least in some local areas) be starting to decline or have very low productivity (J. C. Alonso in litt. 2017, Y. Perlman in litt. 2017). With continued agricultural expansion and climate change likely to impact the species even more into the future, the species is precautionarily considered to be undergoing a moderately rapid decline over a 3 generation period (30 years), which will continue or potentially increase into the future. Should research show the species to be declining at a more moderate rate, it would warrant downlisting to a lower category of threat.
