Role of river valleys in the existence of a large number of bird species is greater than in the breeding period and during seasonal migrations and movements. Total during the year they recorded 102 bird species, including 62 species of breeding period. Feature of the habitat of the valleys of small rivers is the combination in small areas of different habitats. This increases the patchiness of zonal steppe landscape, which allows the expansion of areas along the river beds of individual species. Flood regime of rivers is the determining factor for the birds: The most diverse species composition and abundance of avifauna of individual species in the high-water seasons.
