Gastrointestinal and external parasites of the variable hawk geranoaetus polyosoma (Accipitriformes: Accipitridae) in chile Parasitas gastrointestinais e externos do Falcão Variável Geranoaetus polyosoma (Accipitriformes: Accipitridae) de Chile

Abstract

Information about parasites associated with diurnal raptors from Chile is scarce. Between 2006 and 2017, a total of 15 specimens of the Variable hawk, Geranoaetus polyosoma (Quoy & Gaimard, 1824) were collected, 14 of them from different localities in the Biobío region and one specimen from the Valparaíso region. An external examination of the plumage was made to collect ectoparasites, and necropsies were performed, focusing primarily on the gastrointestinal tract. Chewing lice (Phthiraptera) were found on five (33.3%) of the birds corresponding to three species: 97 specimens of Degeeriella fulva (Giebel, 1874), six specimens of Colpocephalum turbinatum Denny, 1842 and nine belonging to an unidentified species of the genus Craspedorrhynchus Kéler, 1938. Endoparasites found in three (20%) of the birds included round worms (Nematoda) of the genus Procyrnea Chabaud, 1958, and spiny-headed worms (Acanthocephala) of the genus Centrorhynchus Lühe, 1911. The species Colpocephalum turbinatum and the genera: Craspedorrhynchus sp., Procyrnea sp. and Centrorhynchus sp. are new records for the Variable hawk.

No Chile, informações sobre parasitas associados a aves de rapina diurnas são escassas. Entre os anos 2006 e 2017, um total de 15 espécimes do Falcão Variável Geranoaetus polyosoma (Quoy & Gaimard, 1824) mortos, foram examinados, 14 deles provenientes de diferentes localidades da região do Biobío e um espécime na região de Valparaíso. Um exame externo da plumagem foi feito para coletar os ectoparasitas e necropsias do tracto gastrointestinal para coleta de endoparasitas. Cinco aves (33,3%) foram positivas para três espécies de piolhos (Phthiraptera): 97 espécimes de Degeeriella fulva (Giebel, 1874), seis espécimes de Colpocephalum turbinatum Denny, 1842 e nove espécimes não identificados do gênero Craspedorrhynchus Keler, 1938. Endoparasitas foram encontrados em três aves (20%), incluindo vermes redondos (Nematoda) do gênero Procyrnea Chabaud, 1958, e vermes achatados (Acanthocephala) do gênero Centrorhynchus Lühe, 1911. As espécies Colpocephalum turbinatum e os dos gêneros Craspedorrhynchus, Centrorhynchus e Procyrnea corresponderam a novos registros para o Falcão Variável.
