Abstract

The Caatinga harbors 548 species 24of birds, of which 67 species or subspecies originated within the region. The regional avifauna has been assembled over time as a consequence of speciation in situ and biotic exchanges with the adjacent regions. The role played by regional mass extinction remains unknown. Local assemblages range from 90 to 259 species. The richest local assemblages are found in heterogeneous and well-protected landscapes. Both regional and local assemblages exhibit strong seasonality associated with rainfall as bird species are always tracking humid and thus more productive spots. As a consequence, they move within landscapes, between landscapes, and between regions. Although several species are able to cope with the disturbance of their habitats by humans, we predict that no more than 162 species will be able to survive in a degraded Caatinga under a more unpredictable climate regime.
