It is presented a bird survey of Rio Cipó valley from May 1998 to November 2002. The region is within the premises of 'Parque Nacional da Serra do Cipó', one of the most important conservation units of southeastern Brazil. Bird census were carried out through transect, mist-net captures and recording bird vocalizations. Species richness was estimated by jackknife method. It was recorded 226 species, belonging to 43 families. This represents 27% of all 837 bird species recorded at the Cerrado (a Savannah-like biome) region of central Brazil. A total of 2,249 bird individuals were captured with 4,486.82 net-hours. This represented 119 bird species of 23 families. Species richness was estimated at 239 ± 5 species. Six species are considered endemic to this biome: Augastes scutatus (Temminck, 1824) (Trochilidae), Hylocryptus rectirostris (Wied-NeuWied, 1821) (Furnariidae), Antilophia galeata (Lichtenstein, 1832) (Pipridae), Cyanocorax cristatellus (Temminck, 1823) (Corvidae), Charitospiza eucosma (Oberholser, 1905), Saltator atricollis (Vieillot, 1817), and Porphyrospiza caerulescens (Wied-Neuwied, 1830) (Emberizidae). Three species are considered near-threatened to extinction: Sarcoramphus papa (Linnaeus, 1758) (Cathartidae), Cypsnagra hirundinacea (Lesson, 1831), and Charitospiza eucosma (Emberizidae). The Rio Cipó valley holds a significant number of the Cerrado bird species. Some habitats within this biome are becoming rare in the Cerrado region such as gallery forests, and the temporary lagoons along the rivers. Even waterfalls are disappearing in other regions of Brazil. In this sense, the 'Parque Nacional da Serra do Cipó' is achieving one of its aims, which is biodiversity conservation.
