RESUMO:
Anthropic action and destruction of rainforests can completely change terrestrial ecosystems, birds are very affected and consequently related parasitic faunas. The region of the Americas with the highest rate of endangered birds is the Atlantic Forest, with only 10% of native preserved areas suffering fragmentation effects. Parasitic diseases may influence nutrition, reproductive behavior and consequently the population decrease of wild birds
through secondary infections. The circadian rhythm when differentiated in coccidian species, naturally allow multiple infections in passerines, a careful morphological evaluation is necessary to recognize these species. From this perspective the objective of this work was identify and quantify coccidians of wild birds from different Thraupidae subfamilies in 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 half part of potassium dichromate 2.5% K2Cr2O7 solution were collected and sent to the laboratory and processed after sporulation period by centrifugal-flotation method, quantified, photomicrographed and morphologically characterized. Results demonstrate an adaptability of the birds to the coccidians in the wild environment. 13 new reports of coccidian species and 36 possible new species were identified in the Dacninae, Diglossinae, Tachyphoninae, Sporophilinae and Thraupinae subfamilies, as well as an ecological parallel for environmental evaluation by anthropization and altitude in birds of the INP.
