Resumo: | The Cerrado domain is a mosaic of vegetation types at the local scale, and this environmental heterogeneity leads to high regional bird diversity. Therefore, we aimed to survey quantitative and qualitatively the bird fauna of two fragments of Cerrado and to compare them with an adjacent protected area (Estação Ecológica de Itirapina), in order to assess the heterogeneity of bird diversity in the region. The present study was conducted during 12 months from October 2006 to September 2007 in the municipality of Itirapina, Southeastern Brazil. Altogether we recorded 210 bird species. Fifty-six of them had never been detected in Estação Ecológica de Itirapina, and eleven species are new records for the whole Itirapina region. The list also includes six species that are endangered in Sao Paulo State and five endemic species of the Cerrado domain. Most species were recorded in less than 50% of the visits and exhibited low relative abundance. Primarily insectivorous species were the most common, followed by omnivores. Frugivorous birds were poorly represented. Carnivores were more abundant than usually observed in fragments. The similarity among fragments was higher than between fragments and the protected area. Considering the vegetation heterogeneity in the Cerrado domain, our results reinforce the importance of conserving fragments in order to sample this diversity. |
