A total of 15 species of helminths (2 trematodes, 10 nematodes, 2 acanthocephalans, and 1 protozoan) were recovered from 21 crested goshawks (Accipiter trivirgatus formosae) from Taiwan. Sixteen of 21 birds (76.2%) were infected, and 6 of them had ≥4 species of parasites. Most of the parasites were in the gastrointestinal tract. Infection of other sites (e.g., liver, body cavity, air sac) was uncommon. Intensities of infection were low, and no lesions were attributed to the parasites. Most of the species appear to be generalists in raptors and remained generalists in other birds. Lutztrema monoteron, Ascaridia perspicillus, Dispharynx nasuta, Spirocerca sanguinolenta, Raphidascaris sp., and Caryospora sp. are reported here for the first time from Accip. t. formosae. Most of the parasites recovered from Accip. t. formosae require mammals, amphibians, and reptiles as paratenic or intermediate hosts. This article is the first to detail the endoparasites of Accip. t. formosae in Taiwan.
