The relationship between the paleogeographic events of the Neogene and the Quaternary period on Lake Baikal with the formation of the faunistic complexes of fish, birds, and their parasites is analyzed in the article. The composition of fish parasites confirms that the representatives of endemic Baikal Cottoidei passed the most prolonged isolation in Baikal, and the fish of the boreal lowland complex settled the lake relatively recently and may have penetrated here repeatedly. The current composition of aquatic birds indicates the tense conditions of their habitat in the Baikal region in the Quaternary and the significant variability of their fauna in the Pleistocene climatic cycles due to the periodic colonization of Baikal by birds.
