A total of 277 rufous-collared sparrows, Zonotrichia capensis Müller, 1776 (Emberizidae), were examined for external parasites. The birds were captured using mist nets in seven locations in northern and central Chile. Additionally, seven carcasses from central Chile (the Biobío region) were necropsied to evaluate the presence of endoparasite infection. Ectoparasites were found on 35.8% (99/277) of the examined birds and they were represented by the following arthropods: feather mites Amerodectes zonotrichiae Mironov and González-Acuña, 2014 (Analgoidea: Proctophyllodidae), Proctophyllodes polyxenus Atyeo and Braasch, 1966 (Analgoidea: Proctophyllodidae), and Trouessartia capensis Berla, 1959 (Analgoidea: Trouessartiidae); a louse Philopterus sp. (Phthiraptera: Ischnocera); and ticks Amblyomma tigrinum Koch, 1844 (Acari: Ixodidae) and Ixodes auritulus Neumann, 1904 (Acari: Ixodidae). Two of the seven necropsied carcasses were infected with the acanthocephalan Mediorhynchus papillosus Van Cleave, 1916 (Gigantorhynchida: Gigantorhynchidae). To our knowledge, this study reports P. polyxenus, Philopterus sp., A. tigrinum, and M. papillosus for the first time for Z. capensis and expands the distributional range for T. capensis to Chile.

Resumo

Um total de 277 tico-tico Zonotrichia capensis Müller, 1776 (Emberizidae) foram examinados em busca de ectoparasitos. As aves foram capturadas com redes em sete localidades do norte e centro do Chile. Além disso, sete carcaças do centro Chile (Região de Biobío) foram examinadas para avaliar a infecção por endoparasitos. Ectoparasitos foram encontrados em 35,8% (99/277) das aves examinadas com a identificação dos ácaros Amerodectes zonotrichiae Mironov and González-Acuña, 2014 (Analgoidea: Proctophyllodidae), Proctophyllodes polyxenus Atyeo and Braasch, 1966 (Analgoidea: Proctophyllodidae) e Trouessartia capensis Berla, 1959 (Analgoidea: Trouessartiidae), piolho Philopterus sp. (Phthiraptera: Ischnocera) e carrapatos Amblyomma tigrinum Koch, 1844 (Acari: Ixodidea) e Ixodes auritulus Neumann, 1904 (Acari: Ixodidea). Duas das sete carcaças examinadas foram infectadas com o Acantocephala Mediorhynchus papillosus Van Cleave, 1916 (Gigantorhynchida: Gigantorhynchidae). Para o nosso conhecimento, este é o primeiro estudo para descrever P. polyxenus, Philopterus sp., A. tigrinum e M. papillosus em Z. capensis e expande a distribuição de T. capensis ao Chile.

A total of 97 southern silvery grebes (Podiceps occipitalis), which died as the result of an oil spill on the coast of central Chile, were examined for ecto- and endoparasites. Two lice species including Aquanirmus rollandii (Philopteridae) and Pseudomenopon dolium (Menoponidae) were found from 6.2% (6/97) of birds. In 91.7% (89/97) of cases, grebes were infected with some kind of helminths. Three species of gastrointestinal helminths were detected: Eucoleus contortus (Nematoda), Profilicollis bullocki (Acanthocephala), and Confluaria sp. (Cestoda). In addition, Pelecitus fulicaeatrae (Nematoda) was removed from the tibiotarsal-tarsometatarsal articulation in 13.4% (13/97) of the specimens examined. To our knowledge, these are the first records of A. rollandii, E. contortus, and Confluaria sp. as parasites of P. occipitalis. In addition, these findings expand the distributional range of A. rollandii, E. contortus, P. fulicaeatrae, and Confluaria sp. to Chile.

Resumo

Um total de 97 mergulhões-de-orelha-amarela (Podiceps occipitalis), que morreram devido a um derramamento de óleo na costa do Chile central, foram examinados em busca de parasitos internos e externos. Parasitos externos foram encontrados em 6,2% (6/97) das aves, com a identificação de duas espécies de piolhos: Aquanirmus rollandii (Philopteridae) e Pseudomenopon dolium (Menoponidae). Em 91,7% (89/97) dos casos, os mergulhões apresentaram algum tipo de parasito interno. Foram detectadas três espécies de parasitos gastrointestinais: Eucoleus contortus (Nematoda), Profilicollis bullocki (Acanthocephala) e Confluaria sp. (Cestoda). Além disso, Pelecitus fulicaeatrae (Nematoda) foi isolado das articulação tibiotársica e tarsometatarsal em 13,4% (13/97) das aves examinados. Estes resultados correspondem ao primeiro relato de A. rollandii, E. contortus e Confluaria sp. associados com P. occipitalis, e expandem a distribuição destes parasitos e P. fulicaeatrae para o Chile.
