- Аннотация: Aerial surveys of an area of 7360 km2 comprising both public hunting lands and regional specially protected territories of the Nenets Autonomous Okrug were carried out on 3–14 September 2019. Three species of swans, seven species of geese, and 19 species of ducks were recorded. The counted numbers of birds were extrapolated to the area of the NAO as a whole (171 032 km2), taking into account the suitability of the various habitats for each species. The Greylag Goose Anser anser rubrirostris, Common Pochard Aythya ferina, King Eider Somateria spectabilis, and Steller’s Eider Polysticta stelleri were encountered in the region during the autumn migration for the fi rst time. The dominant waterfowl species were theWhooper Swan Cygnus cygnus (4839 individuals counted; extrapolated number 97 400), Tundra Bean Goose Anser fabalis rossicus (39 828; 472 450), White-fronted Goose A. albifrons (126 220; 207 490), and Barnacle Goose Branta leucopsis (103 180; 1 293 300). The most abundant ducks were Eurasian Wigeon Anas penelope (53 140; 395 880), Northern Pintail A. acuta (11 176; 81 780), and Eurasian Teal A. crecca (10 645; 74 640).
