Population justification: Its population size has been estimated at c. 30,000–63,000 individuals based on habitat modelling (Gavashelishvili and Javakhishvili 2010) and c. 11,500–25,500 lekking males (i.e. c. 34,500–76,500 individuals) based on national estimates (BirdLife International 2015).

Trend justification: Population declines, suspected to be moderate over the last ten years, are expected to increase significantly in the near future, owing to increased hunting, habitat degradation and fragmentation brought about by the creation of new roads. Recently published data suggest that the European population may have declined by <20% over the last three generations (19.2 years, based on a generation length estimated by BirdLife to be 6.4 years) (BirdLife International 2015). Europe holds >95% of the global range of this species. In north-west Iran the population is thought to have increased in size from 215 individuals in 2001 to 350 individuals in 2009 (Khaleghizadeh et al. 2011) however it is now suggested that the population may have declined (N. Habibzadeh in litt. 2015). Its habitat in Azerbaijan is reported to be decreasing and under heavy grazing pressure (E. Sultanov in litt. 2015).
