Abstract
Concerning that the cerrado region is one of the most threatened ecosystems and that the Ecological Station of Jatai shelters one of the greater remaining of this bioma in the northeast of Sao Paulo state, this work had two aims: characterize the structure of bird communities of the Jatai Ecological Station and surrounding area, as well as to create a geo-referenced database of local avifauna. Four areas within the city boundaries of Luiz Antonio (Sao Paulo) were studied: The Jatai Ecological Station and the Luiz Antonio Experimental Station (EEJ/EELA), Oitocentos Alqueires (OIT), a fragment of the Umuarama Farm (UMU) and a fragment of the Nossa Senhora da Aparecida Farm (NSA). The qualitative and quantitative survey resulted in the registration of 211 species at the EEJ/EELA, 55 species at the OIT, 41 at the UMU and 62 at the NSA. As far as species diversity, EEJ/EELA present an index of 3,81; the diversity index at OIT was found to be 3,31, and the index obtained at the fragments was 3,63 (UMU) e 3,45 (NSA). As for IPA, among the less abundant species found in the four areas, there are small frugivorous and nectarivorous represented mainly in the Thraupidae and Trochilidae families, as well as insetivorous represented by the Picidae and Dendrocolaptidae families. Despite the low density of these species, the presence of some frugivorous such as Penelope superciliaris and Trogon surrucura, possibly indicates that the study area is still relatively well conserved. Some species were deemed of Special Interest for Conservation (IECO); future studies were recommended on the population abundance and density, displacement, genetics and behavior. We underlined the need for monitoring and following these species over the years, by means of regular observations and annual population surveys. All information obtained through the surveys done in this research project was used to build the Geo-referenced Database Jatai-Aves (BD-JATAI-AVES). This tool enabled u
