PARASITES OF COMMON (STERNA HIRUNDO) AND ARCTIC (STERNA PARADISAEA) TERNS (CHARADRIIFORMES, LARIDAE) IN KARELIA

摘要

The parasite fauna of Common (Sterna hirundo) and Arctic terns (Sterna paradisaea) taken in the springs of 2013-2015 from the coast of Lake Ladoga was studied. Fithteen parasite species of different systematic groups were found: Cestoda (6 species), Trematoda (4 species), Nematoda (2 species), Acanthocephala (2 species), Crustacea (1 species). The Common tern revealed 11 species of parasites, the Arctic one had 7 species. All identified parasites are typical and widespread helminthes of fish-eating birds that are ubiquitous in the Palaearctic. The species Reighardia sternae was recorded in Karelia for the first time.
