The distribution of the ornithological localities in the cerrado region of South America is analysed. When plotted out, the distribution of total sampling localities appears to be even. However, when only those localities at which birds have been sampled in any depth (> 80 specimens collected or >100 species recorded) are considered a different pattern emerges: c.70% of the cerrado region has never been satisfactorily sampled for birds, and similar or worse situations have been reported for other groups of organisms. Priority areas for future ornithological exploration in the cerrado region are most of the states of Tocantins, Maranhão, and Mato Grosso do Sul, southern Goiás, and western Minas Gerais. In these areas, inventory efforts could be focused mainly on the avifaunas of tropical dry forests, gallery forests and “campos rupestres”. Because the biological diversity in the cerrado region is poorly known and most of this region has already been modified by human activity, it is suggested that the most feasible way to define both a set of priority areas for conservation and a coherent reserve system is to focus analyses on ecosystems and landscapes rather than on species, subspecies or populations.
