【 摘 要 】

Montane open-habitats of southeastern Brazil are represented by the campos rupestres (principally in the Espinhaço Range) and by the campos de altitude (in the Serra do Mar and Serra da Mantiqueira). In spite of the occurrence of endemic species in both vegetation types, an analysis and synthesis of their bird communities have never been conducted. In this paper, we present an avifaunal survey of these areas, describe patterns of geographic distribution, and comment on the conservation of those open-habitats and their avifauna. A total of 231 bird species was recorded in the open-habitats of southeastern Brazilian mountaintops. In the campos rupestres, 205 species were recorded, while in the campos de altitude, the total was 123 species. Five patterns of distribution are recognizable among birds occurring in these habitats: non-endemic (191 species), Atlantic Forest endemics (26 species), Cerrado endemics (6 species), Caatinga endemic (1 species), and montane open-habitat endemics (7 species). In spite of the presence of several protected areas in those regions, the existing reserves do not guarantee the conservation of their important vegetation types and their avifaunas under current low levels of implementation. Since several endemic and threatened bird species live in the campos rupestres and campos de altitude, more efforts must be directed for their conservation.
