An updated list of the birds recorded in Serra da Capivara National Park and environs, in the semi-arid caatinga of northeastern Brazil, includes 238 species, of which 193 were recorded in the park. The region has most of the taxa considered as caatinga endemics except for the macaw Anodorhynchus leari and a group mostly associated with the São Francisco valley (Hydropsalis vielliardi, Cranioleuca vulpina reiseri, Schoenophylax phryganophyla petersi and Saltator coerulescens superciliaris). Five species previously listed for the area were excluded due to local extinctions (Rhea americana, Cyanopsitta spixi, Sporophila maximiliani) or misidentifications (Synallaxis gr. ruficapilla, Formicivora grisea). Serra da Capivara, together with nearby Serra das Confusões National Park, forms one of the largest protected mosaics in the caatinga, a biome severally in need of better protection.

Excavation of Toca do Serrote das Moendas, in Piauí state, Brazil revealed a great quantity of fossil wild fauna associated with human remains. In particular, fossils of a cervid (. Blastocerus dichotomus) were found, an animal frequently pictured in ancient rock wall paintings. In a well-defined stratum, two loose teeth of this species were found in close proximity to human bones. The teeth were independently dated by electron spin resonance (ESR) in two laboratories. The ages obtained for the teeth were 29±3ka (thousands of years) and 24±1ka. The concretion layer capping this stratum was dated by optically stimulated luminescence (OSL) of the quartz grains to 21±3ka. As these values were derived independently in three different laboratories, using different methods and equipment, these results are compelling evidence of early habitation in this area. © 2014 Elsevier Ltd.
