Range DescriptionTetrao mlokosiewiczi is endemic to the Greater and Lesser Caucasus mountains, where there are thought to be some 68,000-84,300 individuals spread between Russia (15,000-50,000 individuals), Georgia (40,000-50,000 individuals), Turkey (3,000-4,500 individuals), Armenia (400-800 individuals), Azerbaijan (1,000-1,500 breeding individuals) and Iran (less than 500 individuals)(Gokhelashvili et al. 2003; T. Sviridova in litt. 2000; BirdLife International 2004; S. Klaus in litt. 2005; Khosravifard in litt. 2007; Sultanov 2006; Storch in press). Population estimates have been very variable and data are patchy, partially due to political unrest which has hampered data collection on populations, trends and threats. Spatial modelling has led to considerably lower population estimates: the global population has recently been estimated at 30,203-63,034 individuals based on extent of suitable habitat in range countries (Gavashelishvili and Javakhishvili 2010); conversely, in Turkey the population was thought to perhaps be as low as 1,000 individuals, but based on spatial modelling, may comprise over 4,800 individuals (Gottschalk et al. 2007). Where trend estimates for 1990-2000 are available they tend to show that the population is in decline (Armenia, 10-19%, Azerbaijan, 20-29% and Turkey, 0-19%) and although in Russia the population is apparently stable, rates of decline are widely predicted to increase.
