Abstract: Birds of prey harbor a wide spectrum of various parasites, mostly with a heteroxenous life cycle. However, most reports on their parasites come from Europe. Although the Harris’s hawk (Parabuteo unicinctus) is a widespread species in America, parasitological surveys on this hawk are mostly focused on coprological findings and ectoparasites, with poor attention paid to helminths. The aim of this study was to gather new and additional data on host-parasite associations for the Harris’s hawk. Twenty-nine birds from central and southern Chile were necropsied. Further, nine birds from a rehabilitation center and 22 museum specimens were inspected for ectoparasites. Sixty-eight percent of birds hosted at least one parasite species. Four lice species, one mite species and eight helminth species (five nematodes, two platyhelminthes and one acanthocephalan) were recorded. Parasitic lice Colpocephalum nanum and Nosopon chanabense, and a nematode Cyathostoma (Hovorkonema) americana were recorded for the first time in raptors from the Neotropics. A feather mite, Pseudalloptinus sp., nematodes, Physaloptera alata and Microtetrameres sp., and a trematode Neodiplostomim travassosi, were recorded for the first time in Chile. The presence of diverse heteroxenous helminths reported here in the Harris’s hawk could be explained by the generalist diet of this raptor.

Spanish title: Helmintos e ectoparasitas do gavião-asa-de-telha (Accipitriformes: Parabuteo unicinctus) no Chile: novas associações parasita-hospedeiro para os rapinantes neotropicais

Resumo: As aves de rapina representam uma fonte importante de parasitas heteroxenos. Porém, a maioria dos relatos são da Europa. O gavião-asa-de-telha (Parabuteo unicinctus) é uma espécie amplamente distribuída no continente Americano, porém estudos parasitológicos nessas aves têm documentado achados coprológicos e ectoparasitas, com poucos relatos sobre endoparasitas como helmintos. Por essa razão, o objetivo deste estudo foi descrever novas associações parasita-hospedeiro para o gavião-asa-de-telha e rapinantes neotropicais. Vinte nove aves provenientes do centro e sul do Chile foram submetidas à necropsia. Por outro lado, nove aves de um centro de reabilitação e 22 espécimes de museu foram inspecionados em busca de ectoparasitas. Do total de aves, 68,3% foram identificadas como portadoras de pelo menos uma espécie de parasita. Quatro espécies de piolhos, um ácaro e oito helmintos (cinco nematoides, dois platelmintos e um acantocéfalo) foram registrados. Os piolhos Colpocephalum nanum, Nosopon chanabense e o nematóide Cyathostoma (Hovorkonema) americana são reportados pela primeira vez em rapinantes neotropicais. Colpocephalum nanum, N. chanabense, Pseudalloptinus sp., Physaloptera alata, Microtetrameres sp., C. (H.) americana e Neodiplostomim travassosi, são reportados pela primeira vez no Chile. A diversidade de helmintos heteróxenos, identificados neste trabalho, poderia ser explicada devido à dieta geralista do gavião-asa-de-telha.

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.

Resumo

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.

We describe species of lice collected from 12 species of Chilean diurnal raptors. Sampled raptors were obtained from wildlife rehabilitation centers and zoos, as carcasses found along highways, and from the avian collection of the National Museum of Natural History. Fourteen species of lice were isolated from all raptor hosts, with genus Degeeriella Neumann, 1906 (Philopteridae) and Colpocephalum Nitzsch, 1818 (Menoponidae) the most frequently found (60% and 26% of all lice, respectively). Degeeriella leucopleura (Nitzsch in Giebel, 1874) from Cinereous Harrier (Circus cinereus), D. carruthi Emerson, 1953 from American Kestrel (Falco sparverius) and Colpocephalum maculatum Piaget, 1880 from Southern Caracara (Caracara plancus) were the lice most commonly collected. Including data from previous studies, we found that in Chilean Falconiformes (1) Colpocephalum turbinatum Denny, 1842 is the louse species associated with the greatest number of raptor species, (2) Degeeriella fulva and Laemobothrion tinnunculi are characteristic of the genera of Buteo and Falco, respectively, and (3) the degree of host-specificity is high (76% of all louse species were associated with only one species host). Thus, our results are similar to those observed for other raptor hosts worldwide.

ESPECIES DE PIOJOS EN AVES RAPACES DIURNAS DE CHILE

RESUMEN.—Describimos las especies de piojos encontradas en 12 especies de rapaces diurnas chilenas. Los especı´menes muestreados fueron obtenidos de centros de rescate de fauna silvestre y zoolo´gicos, de aves atropelladas encontradas en carreteras y de colecciones de aves del Museo Nacional de Historia Natural. Catorce especies de piojos fueron aisladas de todas las especies hospederas, siendo los ge´neros Degeeriella Neumann, 1906 (Philopteridae) y Colpocephalum Nitzsch, 1818 (Menoponidae) los ma´s frecuentemente encontrados (60% y 26% de todos los piojos, respectivamente). Las especies de piojos ma´s comunes fueron Degeeriella leucopleura (Nitzsch in Giebel, 1874), encontrada en Circus cinereus, D. carruthi Emerson, 1953, encontrada en Falco sparverius y Colpocephalum maculatum Piaget, 1880, encontrada en Caracara plancus. Incluyendo estudios anteriores, encontramos que en los Falconiformes chilenos (1), Colpocephalum turbinatum Denny, es la especie de piojo asociada con el mayor nu´mero de especies de rapaces, (2) Degeeriella fulva (Giebel, 1874) y Laemobothrion tinnunculi (Linnaeus, 1758) son caracterı´sticos de los ge´neros Buteo y Falco, respectivamente, y (3) el grado de especificidad de hospedero es alto (76% de todas las especies de piojos estuvieron asociadas so´ lo a una especie de hospedero). Ası´, nuestros resultados son similares a los observados para otros hospederos rapaces de otras regiones del mundo.
