This work includes additions to the existing annotated list of birds of the Shushensky Bor National Park, given in the book by ornithologist S.Yu. Petrov and senior state inspector S.V. Chumakov Birds of the Shushensky Bor National Park, published in 2020 in an electronic form. The paper provides general data on the avifauna of the national park, as well as the results of recent studies as of early 2021. The paper provides information on the sightings of 11 bird species that were not previously recorded in the park as a whole: Ptyonoprogne rupestris (Scopoli, 1769); Turdus merula (Linnaeus, 1758); Monticola saxatilis (Linnaeus, 1766); Ficedula hypoleuca (Pallas, 1764) аnd on individual cluster sites Mountain forestry: Podiceps cristatus (Linnaeus, 1758); Crex crex (Linnaeus, 1758); Charadrius dubius (Scopoli, 1786); Turdus obscurus J.F. Gmelin, 1789; Turdus iliacus (Linnaeus, 1766) and Perovsky forestry: Lanius borealis [excubitor] (Vieillot, 1807); Chloris chloris (Linnaeus, 1758), indicating the nature of their stay and biotopic distribution. The paper is illustrated with photographs taken on the territory of both clusters of the national park by employees of the Shushensky Bor National Park and by local birdwatchers.
This paper presents the inventory results of bird species diversity in the area of the Sayano-Shushenskaya Dam. The territory covers the mountainous area of the National Park Shushensky Bor, urban-type settlement Cheryomushki and its surroundings, including a section of the Sayano-Shushensky reservoir in the upper head water of the Sayano-Shushenskaya Dam and the Yenisei channel below the dam. A list of 216 species has been compiled, for 195 there is reliable confirmation of their habitat. The share of migratory-nesting species is 41%, sedentary 14%, migratory species about 31%, wintering and partially wintering 34%. Three species of waterfowl spend winter in the non-freezing areas of the reservoir. Within various high-altitude complexes 10 types of habitats have been identified, where on the basis of quantitative surveys numerous and common bird species have been identified. The maximum species richness was observed for the ornithocoenosis of the floodplain-valley complex. A cluster analysis of the lists of bird species for the selected habitats has been carried out. The analysis showed a high -diversity along the gradient of heights: forest communities of different altitude levels are similar in species lists by no more than 45%, intrazonal and alpine habitats have unique sets of species and are similar to the others by 29%. The lists of birds in subalpine meadows and high-mountain tundras were found to be identical. In winter there is a high correlation of the bird population between the floodplain-valley complex and anthropogenically disturbed territories. Three bird species were found outside the main range and 5 species within the main range, but not previously noted in this area by other researchers.
The paper deals with the dynamics of nesting of the osprey ( Pandion haliaetus Linnaeus, 1758) in the Shushensky Bor National Park and on adjacent sites in the valley of the Yenisei River, associated with the emergence of the Sayano-Shushenskaya hydroelectric power station reservoir. The paper contains data on the nesting of the osprey directly on the territory of the Mountain Forestry of the National Park. Special attention is paid to one of the discovered nests. To build nests, the osprey in the Siberian region usually chooses high-stemmed dry or semi-dry trees with broken tops, and one of the tricks when choosing a nesting site is the elevation above the general level of the surrounding forest to provide a circular view. In this case, the nest was located on the broken top of a live cedar growing on a steep slope in a fir-cedar forest. There were taller trees nearby, i.e. the nest did not dominate in height. During observations of osprey nests, it was found out that they reacted very negatively to the appearance of any watercraft in the bay. If the adult birds were in or near the nest, they flew from a great distance and did not fly close until the boat or motorboat was removed, which, of course, threatened the eggs (when incubating) or chicks during the first weeks after hatching, hypothermia and possibly death. Recommendations are given for the conservation and study of the biology of this rare red book species in the habitat conditions on the mountain-taiga coast of the Sayano-Shushenskaya hydroelectric power station reservoir within the national Park.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
