Abstract:

To describe the parasitic community of the Magellanic Horned Owl, Bubo magellanicus (Aves, Strigiformes), 19 carcasses from central Chile were analyzed. Ectoparasites were collected through plumage inspection, while endoparasites were collected through traditional techniques of parasitological necropsy. Sixteen owls were infected with at least one species of ectoparasite (84.21%) or endoparasite (31.58%). Eleven of 19 birds (57.89%) harbored feather mites of the three species Pandalura cirrata (42.11%), Glaucalges attenuatus (47.37%), and Kramerella sp. (10.53%), whereas 16 individuals (84.21%) harbored the chewing louse Strigiphilus chilensis. Only six birds (31.58%) were infected with helminths; the nematodes Capillaria tenuissima (26.32%) and Dispharynx nasuta (5.26%); the acanthocephalan Centrorhynchus spinosus (5.26%); and the trematode Neodiplostomum sp. (5.26%). Apart from S. chilensis, all parasites comprised new records for B. magellanicus.

Resumo: Para descrever a comunidade parasitária de coruja-orelhuda Bubo magellanicus (Aves, Strigiformes), foram analisados 19 carcaças das aves do centro do Chile. Os ectoparasitos foram coletados inspecionando-se a plumagem e os endoparasitas extraídos por meio de técnicas tradicionais de necropsia parasitaria. Dezesseis corujas estavam infectadas com pelo menos uma espécie de ectoparasito (84,21%) ou endoparasito (31,58%). Onze de 19 aves (57,89%) abrigavam nas penas ácaros de três espécies: Pandalura cirrata (42,11%), Glaucalges attenuatus (47,37%) e Kramerella sp. (10,53%), enquanto que 16 indivíduos (84,21%) estavam parasitados pelo piolho Strigiphilus chilensis. Apenas seis aves (31,58%) estavam infectadas com helmintos; os nematoides Capillaria tenuissima (26,32%) e Dispharynx nasuta (5,26%); o acantocéfalo Centrorhynchus spinosus (5,26%); e o trematódeo Neodiplostomum sp. (5,26%). Excetuando-se S. chilensis, todos os parasitos incluíam novos registros para B. magellanicus.
