| Sumario: | The study of bird communities in urban green areas is of fundamental importance for understanding the impacts of urbanization on the environment. Thus, the objective of this study was to survey the assemblage of birds from fragmented remnants of the Atlantic Forest in the urban environment of the municipality of Santa Cruz do Sul. The survey was carried out between October 2021 and April 2022, with two surveys per season of the year, in each of the three sampling areas. A total of 104 bird species were recorded, distributed in 44 families. The most representative families were Tyrannidae, Thraupidae and Furnariidae groups whose species are more tolerant to urbanized environments. In total, 87 species (83.6%) were classified as resident, and the remaining 17 species (16.3%) as summer residents. As for the food structure of the sampled areas, the guild with the highest number of representatives was the omnivore (n=37), followed by the insectivore (n=35). Regarding species richness in the sampled areas, there was a greater number of records in area 2 (n=80). The season with the highest number of total species was spring (n=97). All areas had a high number of species classified as uncommon species (A1: 48, A2: 66, A3: 59). In all sampling areas, the sample sufficiency curve stabilized after the second summer survey. The great diversity of species found in the sampling areas corroborates the importance of green areas in the urban environment for local biodiversity. |
