Abstract

The savannas of Roraima-Rupununi region represent the largest savanna enclave in Amazonia. They are distributed across northern Brazil (state of Roraima) and southern Guyana (Rupununi). The avifauna of the Rupununi savannas is well-know, but no synthesis is available yet on birds recorded in the savannas of Roraima. This paper aims to present a systematic list of birds recorded to date on the savannas of the Brazilian state of Roraima. A total of 306 species of birds distributed in 60 families occur in the Roraima savannas, 93.7% of which are resident and only 19 species are migratory. Three species of the Roraima/Rupununi savannas are considered endemic to this area (Aratinga solstitialis, Synallaxis kollari and Campylorhynchus griseus), while two are regarded as globally threatened (Synallaxis kollari and Cercomacra carbonaria). A gap-analysis contrasting the distribution of the savannas with that of the network of protected areas in Roraima revealed that only 1.41% of the savannas distributed in the state are protected by reserves. We recommend an urgent increase in the number of protected areas within Roraima, with priority for the establishment of new conservation units protecting extensive areas of savannas.
