Impact of the functioning of a thermeletry in the bird fauna of the brazilian semiarid

Abstract

The thermoelectric generate a large amount of pollutants, due to the type of fuel used for electric power generation, damaging in this way, the environment, human health, as well as the surrounding biodiversity. Based on this premise, the objective of this work was to identify the bird species present in the surroundings of a thermoelectric. The study was carried out in the surroundings of the Borborema Energética SA Thermoelectric, in the region of the northeast of Brazil, from January to December 2016, where used the technique of observation by transects and use of mist net to capture images of the birds fauna. In the study area, 29 bird species belonging to 10 orders and 21 families were registered. The order with the most representatives was the Passeriformes, and the families were Tyrannidae, followed by Furnariidae. Of the total number of journeys performed during the daytime of the research, the species with the highest observation frequency was Crotophaga ani. On the abundance, more representatives were the species Crotophaga ani, Coragyps atratus and Thlypopsis sordida. In this context, there was a low abundance and diversity of birds fauna in the region, demonstrating a precarious state of conservation and ecological integrity, which may reflect the impacts of industrialization, installation and operation of the thermoelectric in the area.
