The current state of the ornithological fauna of the Krasnoyarsk Reservoir

This paper discusses the current state of the avifauna on the territory of the Krasnoyarsk Reservoir. To date, the species composition of birds in the study area has not been studied, although it is worth noting the need to study the distribution of birds in this area. The construction of the Krasnoyarsk hydroelectric power station led to changes in the hydrological regime of the Yenisei River with subsequent flooding of the surrounding territory, as a result of which various geological processes of collapse of the Krasnoyarsk Reservoir banks are observed. Bank metamorphoses can also influence the spatial distribution of birds and creation of new ornithocomplexes. Our ecological and faunal analysis was carried out over two years (2018–2019) at nine key points along the bank lines of the Krasnoyarsk Reservoir within a radius of one kilometer from the water to identify the impact of geological changes in the banks on the nature of bird placement. The key areas of the study were determined, taking into account various biotopic habitat conditions that attract birds. Monitoring of avifauna on the territory of the Krasnoyarsk Reservoir will allow us to assess the degree of influence of changes in the geological processes of the banks on the spatial and biotopic distribution of birds, and it is also possible to forecast the disappearance or movement of some species and subspecies on this territory.
