Studies of parasitism in chinstrap penguins (Pygoscelis antarctica) are infrequent and mainly refer to the identification and description of its parasites, with little ecological data. In an attempt to address that lack of knowledge, we collected endo- and ecto-parasites from 326 live and four dead of chinstrap penguins, in three different localities of Antarctica not studied before. Three species of endoparasites and two of ectoparasites were found parasitizing birds: two tapeworms, Tetrabothrius pauliani (Cestoda: Tetrabothriidae) and Parorchites zederi (Cestoda: Dilepididae); one roundworm, Stegophorus macronectes (Nematoda: Acuariidae), and one feather louse: Austrogoniodes gressitti (Insecta: Phthiraptera: Philopteridae). Ticks (Ixodes uriae—Acari: Ixodidae) were collected from the ground near the penguin nesting colonies at two localities, Shirreff Cape and Narebsky Point. New ecological data are given for the two species of ectoparasites. No parasites were found in the blood collected from 300 live penguin

Abstract

The Neotropic cormorant Nannopterum (Phalacrocorax) brasilianus (Suliformes: Phalacrocoracidae) is widely distributed in Central and South America. In Chile, information about parasites for this species is limited to helminths and nematodes, and little is known about other parasite groups. This study documents the parasitic fauna present in 80 Neotropic cormorants’ carcasses collected from 2001 to 2008 in Antofagasta, Biobío, and Ñuble regions. Birds were externally inspected for ectoparasites and necropsies were performed to examine digestive and respiratory organs in search of endoparasites. Ectoparasites collected were cleared and mounted for identification under a microscope. Fecal samples were also evaluated to determine the presence of protozoan parasites employing a flotation technique. A total of 44 (42.5%) of birds were infested with at least one ectoparasite species, while 77 (96.25%) were carrying endoparasites. No protozoan forms were found after examination. Most prevalent endoparasite species found were Contracaecum rudolphii s. l. (72/80, 90%), followed by Pectinopygus gyroceras (33/80, 41.25%), and Profilicollis altmani (26/80, 32.5%). This is the first report of P. altmani, Baruscapillaria carbonis, Avioserpens sp., Cyathostoma (Cyathostoma) phenisci, and Eidmaniella pelucida in the Neotropic cormorant. These findings also expand the distributional range of Andracantha phalacrocoracis, Paradilepis caballeroi, Hysteromorpha triloba, and P. gyroceras to Chile.

Resumo

O Biguá Nannopterum (Phalacrocorax) brasilianus (Suliformes: Phalacrocoracidae) é amplamente distribuído na América Central e na do Sul. No Chile, as informações sobre parasitos para essa espécie são limitadas a helmintos e nematoides, e pouco se sabe sobre outros grupos de parasitos. Este estudo documenta a fauna parasitária presente em 80 biguás coletados de 2001 a 2008, nas regiões de Antofagasta, Biobío e Ñuble. As aves foram inspecionadas externamente em busca de ectoparasitas; adicionalmente, foram realizadas necropsias para examinar os órgãos digestivos e respiratórios em busca de endoparasitos. Os ectoparasitos coletados foram limpos e montados para identificação ao microscópio. As amostras de fezes também foram avaliadas para determinar a presença de parasitos protozoários, empregando-se uma técnica de flutuação. Um total de 44 (42,5%) aves estavam infectadas com pelo menos um ectoparasito, enquanto 77 (96,25%) estavam portando endoparasito. Nenhuma forma de protozoário foi encontrada após o exame. As espécies de endoparasitos mais prevalentes encontradas foram Contracaecum rudolphii (72/80, 90%), Pectinopygus gyroceras (33/80, 41.25%) e Profilicollis altmani (26/80, 32.5%). Este é o primeiro registro de P. altmani, Baruscapillaria carbonis, Avioserpens sp., Cyathostoma (Cyathostoma) phenisci e Eidmaniella pelucida no biguá. Esses resultados também expandem a distribuição de Andracantha phalacrocoracis, Paradilepis caballeroi, Ascocotyle felippei, Hysteromorpha triloba e P. gyroceras no Chile.

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.

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.

Despite being a bird with a broad and extensive distribution in Chile, the black-chinned siskin, Spinus barbatus Molina, 1782 is not well studied in relation to its parasites. This paper aims to describe the ectoparasite fauna of S. barbatus in central and southern Chile. A total of 125 individuals caught with mist nets were examined alive; a total of 22 parasites were found dead and were exposed to parasitic autopsy. The extracted parasites were preserved in 70% alcohol for subsequent mounting and identification. Ectoparasites were found in 56 black-chinned siskins (38%); 48 of them (33%) had 870 mites – 680 feather mites (Astigmata: Analgoidea) were identified as Proctophyllodes spini, 167 as Knemidokoptes jamaicensis, 19 as Strelkoviacarus critesi, and one as Analges passerinus. Moreover, three mites were chiggers belonging to the tribe Schoengastiini (Prostigmata: Trombiculidae). In 21 birds (14%), 54 lice were found, 21 of which were identified as Philopterus roehreri, 18 as Myrsidea serini, and 15 as Ricinus carolynae. Endoparasites were not found in the necropsied individuals. All of the parasites that were found represent new records for Chile, and they also serve as new records of host–parasite associations for S. barbatus.

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.
