Pesquisa do Estado do Rio de Janeiro CNPQ - Conselho Nacional de Desenvolvimento Cient?fico e Tecnol?gico Anthropic action and the destruction of tropical forests can completely change terrestrial ecosystems, birds are very affected and consequently related parasitic fauna, the parasitism can influence nutrition and favor the appearance of secondary infections in wild birds. A careful morphological evaluation is necessary to identify coccidian species, from this perspective, the objective of this work was to identify and quantify coccidia of wild birds from different subfamilies of Thraupidae in the Itatiaia National Park (INP), classifying as species, new descriptions and/or new hosts. Expeditions take place in and around the park, the passerines were collected through mist nets, examined and then released. Samples with carried to the laboratory and processed after sporulation by centrifugal-flotation method, quantified, photomicrographed and morphologically characterized. Results suggest the adaptability of birds to coccidia in the wild environment. Thirteen new reports of coccidian species and 36 possible new species were observed in the subfamilies Dacninae, Diglossinae, Tachyphoninae, Sporophilinae and Thraupinae A a??o antr?pica e a destrui??o das florestas tropicais pode alterar completamente os ecossistemas terrestres, as aves s?o grandes afetadas e consequentemente as faunas parasit?rias relacionadas a estas, as parasitoses podem influenciar na nutri??o e favorecer o aparecimento de infec??es secund?rias em aves silvestres. ? necess?ria uma avalia??o morfol?gica cuidadosa na identifica??o dessas esp?cies, sob esta ?tica o objetivo deste trabalho foi identificar e quantificar cocc?dios de aves silvestres de diferentes subfam?lias de Thraupidae no Parque Nacional de Itatiaia (PNI), identificando e classificando as esp?cies, atrav?s de novas descri??es e/ou novos hospedeiros. Expedi??es ocorreram no PNI e no seu entorno, os passeriformes foram capturados atrav?s de redes de neblina, caracterizados, examinados e soltos em seguida. Amostras com parte fezes e parte solu??o de dicromato de pot?sso (K2Cr2O7) a 2,5% foram coletadas e encaminhadas para o laborat?rio e processadas pelo m?todo de centr?fugo-flutua??o, quantificadas, fotomicrografadas e caracterizadas morfologicamente. Resultados sugerem a adaptabilidade das aves aos cocc?dios no ambiente silvestre. No total 13 novos relatos de esp?cies de cocc?dios e 36 poss?veis novas esp?cies foram observadas nas subfam?lias Dacninae, Diglossinae, Tachyphoninae, Sporophilinae e Thraupinae.
