摘要：
The results of our survey of bustards in the southern part of the Saratov Trans-Volga region over an area of 12000 sq. km in 1990-2010 are presented; analysis of the abundance dynamics is performed; and the factors causing it are revealed. Data on the distribution of bustards over their biotopes in the period of premigration roaming are studied, and the demographic and spatial structure of the population is analyzed.
