This study was aimed at describing the community of arthropod ectoparasites associated with sympatric populations of Turdus amaurochalinus and Turdus rufiventris and analyzing the aggregation patterns of the chewing lice species, during reproductive and nonreproductive periods, of both Turdus species in three areas of the Atlantic forest in southern Rio Grande do Sul state (RS), Brazil. Altogether, we captured 36 specimens of T. amaurochalinus and 53 specimens of T. rufiventris. We identified two families of chewing lice, Menoponidae and Philopteridae, with Myrsidea and Brueelia as the most prevalent and abundant on both host birds. The lowest aggregation levels of chewing lice Myrsidea and Brueelia occurred during the reproductive period of both host species, suggesting a reproductive synchronization and a dispersion period. The most prevalent feather mite on T. amaurochalinus was Proctophyllodes weigoldi, and on T. rufiventris, Trouessartia serrana. Analges sp. and Pteronyssoides sp. were not observed on T. rufiventris. We identified three species of ticks; Ixodes auritulus was the most prevalent and abundant on the birds. Ornithoica vicina was the only hippoboscid fly collected, and only on T. amaurochalinus. The richness of ectoparasites was greater on T. amaurochalinus than on T. rufiventris. For T. amaurochalinus, the mean richness was lesser in winter compared to spring and autumn; however, we observed no variation in the mean richness of ectoparasites for T. rufiventris during the same seasons.
