Resumo

The results of our study of the abundance dynamics of the great bustard population in the southern part of the Saratov Trans-Volga region for the period from 1998 to 2015 are presented on the basis of censuses carried out before the migration for wintering in the fall and on leks in the spring. The abundance dynamics was analyzed, and the factors causing it were identified. Data on the distribution of the great bustard population density over an account area of 12000 km2 are presented.
