CHECK-LIST OF BIRD SPECIES FROM PIAUÍ STATE, BRAZIL

Abstract

Piauí is inserted between two important biomes, the Cerrado and the Caatinga. The transition areas, demonstrate unique characteristics and derived from adjacent biomes, thus presenting a high number of species of different types of habitats. Studies that have specific data on the occurrence of species are essential for the knowledge and conservation of the biodiversity of a region. The article aims to present the species of birds recorded in the state of Piauí, analysing the conservation status of the species. For this survey a systematic review is being used through indexers such as Google Scholar, Scielo and virtual libraries of Higher Education Institutions. A single table with all the species found in the surveys and maps was made to help visualize the municipalities that have scientific publications. The state of Piauí has 224 municipalities, of these only 35 have a survey of the avifauna with 143 publications between 1982 and 2022, which recorded 487 species of birds in the territory of Piauí. Of these records 36 species (7.4%) are classified with some degree of threat according to the IUCN and MMA. The studies are concentrated in the north and south, with few studies in the center of the state. Analyzing the map of the state of Piauí it was possible to observe that the Conservation Units are also concentrated in the northern and southern regions of the state. Thus, most of the studies were carried out in Conservation Units, and the surveys found outside Conservation Units are within Priority Areas for Conservation.
