Birds of Serra de Santo Antônio State Park, Campo Maior, Piauí, Brazil

This study was motivated by the need to understand the diversity, structure and conservation of the bird community in the Serra de Santo Antônio State Park, contributing to scientific knowledge, the elaboration of the Management Plan and the formulation of management strategies conservation. Its objectives were to identify which bird species are present in the area, what the structure and diversity of this community is like and how the species are distributed in the different trophic guilds. This study is aimed at researchers, managers of Conservation Units, ornithologists, and professionals involved in biodiversity conservation strategies in Caatinga, providing relevant information for decision-making. Two sampling campaigns were conducted during the dry and rainy seasons, using the Point Abundance Index (IPA) method, covering 105 sampling points, recording 161 birds species, of which six species are endemic to the Caatinga and one to the Cerrado. The bird community was characterized by high diversity, with a predominance of insectivorous species. No species were classified as threatened at the national level, but two were categorized as near-threatened globally. The results indicate the importance of the Serra de Santo Antônio State Park for the conservation of local avifauna and the presence of endemic species emphasizes the need for specific conservation measures, especially in the face of threats associated with deforestation, habitat loss, hunting, and illegal trade. The study contributes to the understanding of biodiversity in the region and provides support for effective preservation strategies.
