The distribution of prey birds helminths was studied in the territory of the Central region of Russia. According to the results of the study, the total extensiveness of invasion in two families of birds of prey was 96.8 % (93 out of 96 birds were infested), from them the family Falconidae the infection was 66.2 % (20 out of 30), Accipitridae - 95.4 % (63 out of 66). An important fact is that all studied birds were simultaneously infected with two or more types of helminths. Seventeen species of helminths have been identified, including four species of trematodes: Neodiplostomum attenuatum, Strigea falconis, Strigea vandenbrokae, Plagiorchis elegans, one species of cestodes: Cladotaenia globifera, ten species of nematodes: Cyathostoma americana Physaloptera alata, Physaloptera apivori Synhimantus laticeps Porrocaecum angusticolle Porrocaecum depressum Eucoleus dispar Baruscapillaria falconis Capillaria tenuissima Capillaria sp. and two species of acanthocephalus: Centrorhynchus aluconis, Centrorhynchus globocaudatus. The helminthic faunal complexes included two or more types of helminths in each infected bird. As a result of the work, new hosts for the following helminth species were noted for the first time: the trematodes Neodiplostomum attenuatum (Falco tinnunculus and Pernis apivorus), Strigea falconis (Falco tinnunculus), Strigea vandenbrokae (Pernis apivorus), nematodes: Cyathostoma americana (Circus aeruginosus and Accipiter gentilis) Physaloptera apivori (Accipiter gentilis), Porrocaecum angusticolle (Accipiter nisus), Baruscapillaria falconis (Pernis apivorus).
