Migration and Nesting of Eagles in the Upper Reaches of Angara River

The work was carried out in 2009–2018 in the sources of Angara river and adjacent areas, using commonly accepted methods of recording birds, adapted to local conditions (Ravkin, Chelintsev, 1990; Melnikov, 2016). All birds noted on walking routes were recorded. The total length of routes is more than 4300 km. Systematics and the order of species descriptions are according to the latest Russian bird report (Koblik et al., 2006). A preliminary analysis of materials on birds of prey is in a previous publication (Melnikov, 2016). Of the birds of prey featured in the upcoming conference, there is Osprey (Pandion haliaetus), Greater Spotted Eagle (Aquila clanga), Golden Eagle (Aquila chrysaetos) and White-Tailed Eagle (Haliaeetus albicilla)
