The purpose of the research is to study the infection of diurnal birds of prey of the order Falconiformes with helminths and to determine the helminth species composition by the example of the Noyev Kovcheg Conservation Nature’s Nursery in the Altai Territory.Materials and methods. We studied diurnal birds of prey of the order Falconiformes for helminthosis in the Altai Territory, in the Noyev Kovcheg Conservation Nature’s Nursery, in 2022. For the parasitological study of birds, we used laboratory methods of helminthocoprological studies: helminthoovoscopy and helminthoscopy. Species identification was determined by characteristic morphological features of helminth eggs, larvae and fragments. To assess the infeсtion with certain types of helminths, we used standard indicators for parasitological research, namely, infection prevalence and infection intensity amplitude.Results and discussion. In 58 studied diurnal birds of prey of the order Falconiformes, 8 helminth species were identified of which 6 nematode species, namely, Ascaridia galli, Tetrameres sobolevi, Capillaria caudinflata, Heterakis gallinarum, Trichostrongylus spp., and Singamus trachea; 1 trematode species, Strigea spp.; and 1 cestode species, Raillietina echinobothrida. These species occurred throughout all seasons of 2022.
