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 Biob\ío region and one specimen from the Valpara\íso 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 K\éler, 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 L\ühe, 1911. The species Colpocephalum turbinatum and the genera: Craspedorrhynchus sp., Procyrnea sp. and Centrorhynchus sp. are new records for the Variable hawk.

Resumo

No Chile, informa\ç\ões sobre parasitas associados a aves de rapina diurnas s\ão escassas. Entre os anos 2006 e 2017, um total de 15 esp\écimes do Falc\ão Vari\ável Geranoaetus polyosoma (Quoy \& Gaimard, 1824) mortos, foram examinados, 14 deles provenientes de diferentes localidades da regi\ão do Biob\ío e um esp\écime na regi\ão de Valpara\íso. 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 tr\ês esp\écies de piolhos (Phthiraptera): 97 esp\écimes de Degeeriella fulva (Giebel, 1874), seis esp\écimes de Colpocephalum turbinatum Denny, 1842 e nove esp\écimes n\ão identificados do g\ênero Craspedorrhynchus Keler, 1938. Endoparasitas foram encontrados em tr\ês aves (20\%), incluindo vermes redondos (Nematoda) do g\ênero Procyrnea Chabaud, 1958, e vermes achatados (Acanthocephala) do g\ênero Centrorhynchus L\ühe, 1911. As esp\écies Colpocephalum turbinatum e os dos g\êneros Craspedorrhynchus, Centrorhynchus e Procyrnea corresponderam a novos registros para o Falc\ão Vari\ável.
