Wild birds are hosts of a variety of parasites. Their migratory behavior increases the dispersion of parasites and consequently the occurrence of diseases in various locations around the world. To identify the parasitological fauna of wild birds in the Tinguá Biological Reserve in Rio de Janeiro state-Brazil, 43 birds belonging to the orders Passeriformes and Columbiformes were captured and stool samples collected. Four birds (9.3%) were positive for parasites. In the fecal samples, trematode eggs of the Tanaisia sp and oocysts of coccidia as Isospora sp were found. The low parasite prevalence in wild birds found in this study may be an environmental quality indicator,because the reserve is a preserved area that has little human interference. We emphasize also thatthe use of the technique of collecting stool samples with anal swabs was successful for diagnostic purposes.

The frequency of intestinal parasites was established in 5 species of bats of the family Phyllostomidae captured in three different areas of study, located in the Village of Tinguá located in the far northeast of the city of Nova Iguaçu and the southern limits Tinguá Biological Reserve, in the State of Rio de Janeiro, Brazil in April and July 2012. Each fecal sample was individually analyzed and processed by a modified centrifugal flotation procedure in sucrose solution. No eggs or cysts of endoparasites were detected in the 33 samples analyzed. This is the first study of the fauna endoparasites in bats using centrifugal flotation technique using only fecal samples. All surveys are based on necropsy of examined hosts.
