The southern part of Central Siberia is an attractive and promising region for ornithologists. This region is distinguished by biodiversity, uniqueness of natural landscapes, minimal anthropogenic changes. It is known that at different time intervals the number, diversity, knowledge of the representatives of these families was unequal. Significant changes have occurred due to climate change. A distinctive feature of global warming occurring in the XX-XXI centuries is that it occurs under conditions of intense anthropogenic impact on nature. The economic development of the southern part of Central Siberia led to a change in the zoogeographic barrier, as a result of which many European species spread widely both in the eastern and northern directions. The most intense changes are characteristic of the Corvidae family. They are considered birds that spread northward. Representatives of the Vranov family (Corvidae) in the southern part of Central Siberia in the early 1900s were considered rare birds. Around the beginning of the twentieth century, representatives of the Vranov family occupied a space of at least 200 km. In recent years, there has been a wide distribution of representatives of the Vranov family to the subtaiga regions of Central Siberia. The family Thrush (Turdidae) is described as birds forming supraspecific complexes. They are characterized by such features as significant morphological differences; a certain level of reproductive isolation; independence; traits of a polytypic species (communication in areas of secondary contact through certain zones of hybridization).

Keywords:Central Siberia, Corvids (Corvidae), Blackbirds (Turdidae), dispersal, supraspecific complexes, warming, biodiversity.
