For the first time, the feeding stations, the number and the density of the species were determined in the region. The 98.09% of the number of it has inhabited in the Gizilaghaj State Nature Reserve, the 9.25% in the areas apart the reserve. In 1 km² its density was 4.74 individuals in the reserve, but 0.03 individual in the areas apart the reserve.The main reason of the few number of it were grazed a lot of large and small-cattle in the areas apart the reserve. But in the reserve the main reason of the ordinary number of it were the lack of negative impact of the anthropogenic factors, the rich of the feed resources of the open swamps and shallow water areas which were the feeding areas.
