The results of original studies on the helminth fauna of the black-legged kittiwake ( Rissa tridactyla L.) (ten ad. and ten juv.) in the northern part of the Kara Sea (Severnaya Zemlya Archipelago and Wiese Island) carried out in the years 2019–2020 are presented. Eight species of helminths (one trematode, four cestodes, and three nematodes) have been registered. For the first time in seabirds in the high latitudes of the Arctic, the trematode Diplostomum sp. and the nematode Paracuaria adunca have been recorded. Adult birds have been established to be infected mainly with cestodes of the family Dilepididae while nestlings mainly have cestodes of the family Tetrabothriidae. The presence of five common species in the helminth fauna of kittiwakes in the northern part of the Kara Sea and in the northern part of Novaya Zemlya (Severnyi Island) has been noted due to the similarity of the feeding range of the birds in these areas. Possible causes for the features revealed in the infection of kittiwakes (food preferences, distribution of the foci of invasion, and the influence of abiotic factors) are analyzed.
