The species included in the analysis are the following: Anas acuta, Anser albifrons, Anser anser, Anser brachyrhynchus, Anas clypeata, Anas crecca, Anser erythropus, Anser fabalis, Aythya ferina, Aythya fuligula, Aythya marila, Aythya nyroca, Anas penelope, Anas platyrhynchos, Anas querquedula, Anas strepera, Branta bernicla, Bucephala clangula, Branta leucopsis, Branta ruficollis, Cygnus columbianus, Cygnus cygnus, Clangula hyemalis, Cygnus olor, Mergellus albellus, Marmaronetta angustirostris, Melanitta fusca, Mergus merganser, Melanitta nigra, Mergus serrator
, Netta rufina, Oxyura leucocephala, Polysticta stelleri, Somateria mollissima, Tadorna ferruginea, Tadorna tadorna.
Low numbers of northern pintails (Anas acuta) and red-breasted mergansers (Mergus serrator) were also observed along the mainland coastline and the shorelines of barrier islands from Barrow to Demarcation Point.

They are joined in July by long-tailed ducks, surf scoters (Melanitta perspicillata), and more white-winged scoters, as well as by some scaup (Aythya) and red-breasted mergansers (Mergus serrator
) (Barry and Barry, 1982; Alexander et al., 1988; Cornish and Dickson, 1994).
The larger number of Anseriformes appears to result from the greater number of European flyway species (e.g., Cygnus cygnus) and boreal species (e.g., Melanitta nigra and Mergus serrator) that occur because certain habitat features extend farther north along the Lena River toward the delta.
