Nesting and Abundance of the Osprey on the Territory of the Sayano-Shushenskij Reserve and in Its Protected Area

Abstract

The article contains data on the nesting of scopa on the coasts of the Sayano-Shushenskaya hydroelectric power station reservoir within the Sayano-Shushenskij Reserve. Before the formation of the largest artificial reservoir on the banks of the Yenisej River, 3–4 pairs of ospreys nested. The low number was probably determined by the unsuitable conditions associated with the lack of places for the construction of nests. Flooding of mountain areas contributed to the formation of loan areas, as well as an increase in the number of fish resources that the osprey feeds on. In 2022, 12 residential nests were registered in the protected area of the reservoir, in each of which breeding was noted. A significant role in the development of the osprey population, along with natural habitats, is played by the strict protection regime characteristic of biosphere reserves.
