 	abstract = "Ecological mechanisms that allow the coexistence of five species of the genus Turdus (Turdidae) in an urban fragment in souther Brazil seem to be not easily explained. In this context, the present work tried to comprehend how the birds community is structured as well as to investigate possible patterns and mechanisms that make possible the coexistence of two related and relatively similar species (T. leucomelas and T. rufiventris). Mist nets were used for sampling, which made possible to describe the structure of the community with ecological and morphological data of five species of the genus. For the coexistence analysis between T. leucomelas and T. rufiventris, we surveyed parameters as average abundance per sampled environment in comparison to seasons, forest stratum used by birds, morphological aspects, and diet. Results indicated that Turdus rufiventris is the most abundant thrush that occurs in the area and is the most constant throughout this study, present in 66% of captures. Turdus leucomelas comes next with occurrence on 55% of captures. Turdus amaurochalinus, with 84% of occurrence in spring (57% yearly), may present overlap of migrant populations over resident ones along the same season. On its turn, Turdus albicollis was considered supplementary with maximum frequency of 30% in winter. As for its dominance, Turdus subalaris was regarded as recessive and occasional in its Constance in captures. Comparisons made between T. leucomelas and T. rufiventris show great resemblance of body mass, while in other variables, such as length, there was significant difference. However, T. rufiventris presents higher extents of variation and thinner and longer beaks. Both species were also very similar in occurrence on the surveyed environments - exposed border, transition, and inner forest. The species exhibited a generalist diet with trophic niche amplitude higher for T. rufiventris with overlap of some food resources. Certain segregation in regards to occupied forest strata was detected, mainly in the fragments border, though this must not be the key factor for coexistence.",
