[Parasites of Austrian birds of prey (Falconiformes)]

During the examination of 158 birds of prey -- Buteo buteo (85), Falco tinnunculus (30), Accipiter gentilis (19), Accipiter nisus (18), Circus aeruginosus (2), Circus pygargus (1), Pandion haliaetus (1), Pernis apivorus (1), Falco subbuteo (1) and faeces samples of Falco tinnunculus 4 protozoan species, 1 trematode species, 2 cestode species, 13 nematode species, 2 acanthocephalan species and 5 mallophaga species could be detected. In the buzzard, kestrel and goshawk a new species of Capillaria could be found and described as Eucoleus suppereri spec. nov. A new species of Synhimantus, Synhimantus (Dispharynx) falconis spec. nov. was diagnosed. The infestation frequency of endo- and ectoparasites was relatively high, whereas the infestation intensity was small or mediocre on an average. The highest rate of infestation was found with trematodes and cestodes. The significance of the analysis of crop- and stomach-cntents as a guarantee of diagnosis "psuedoparasitism" was pointed out.
