Justification of Red List category
This species has suffered rapid population reductions across most of its range owing to the loss, degradation and fragmentation of its habitat, as well as hunting. Some populations in its Iberian stronghold have been suggested to have stabilised and possibly increased, although there is now some evidence for at least local declines in some areas in this region. Additionally, hunting in Central and East Asia results in high rates of adult mortality, and land-use changes in eastern Europe, Russia, Central Asia and Morocco may have a significant impact on this species's population and the extent of its remaining habitat, such that it is likely to decline at a rapid rate over the next three generations. It therefore qualifies as Vulnerable. Should research show the species to be declining at a more moderate rate, it would warrant downlisting to a lower category of threat.
